Cystic Renal Lesions

Introduction. Cystic renal lesions are very heterogeneous lesions which differ in ethiopathogenesis, morphological and clinical manifestations, and also in evolution and therapy. Classification of cystic lesions is complex, symptomatology is poor, and diagnosis is based on complete radiological diagnostic procedures. Case report. We presented a 20-year old patient with mild subjective symptoms. Objectively, he was without positive clinical signs and changes in biochemistry of blood. Using ultrasonography (US) multiple serous simple cysts were found in both kidneys. Using computed tomography (CT) multiple serous cysts were found, without changes in cystic walls, with preserved renal parenchyma and without cystic changes on other parenchymatous organs. Conclusion. Although renal cystic lesions are frequent in adult population, this is a rare example of a young adult man with simple, gigantic, serous cysts which do not produce clinical manifestations nor functional renal difficulty so far.

Context.—Cystic lesions of the kidney may be accompanied by a range of neoplasms with distinct prognoses and future risks of developing additional tumors. In addition, some renal tumors, with or without accompanying renal cysts, may show a prominent cystic component. In the adult population, neoplasms occurring in a background of renal cystic diseases and cystic renal neoplasms often pose diagnostic challenges because of their many overlapping features. Objective.—To review the clinicopathologic characteristics of common entities in the spectrum of neoplastic and potential preneoplastic cystic lesions encountered in adults, with an emphasis on renal cystic diseases associated with tumor development and on renal neoplasms with predominantly cystic morphology. Data Sources.—The relevant English-language literature was reviewed, accompanied by the authors' experience at their practicing institution. Conclusions.—The presence of multiple renal cysts, both acquired and syndromic, can be associated with a variety of renal tumors. The morphology of the cysts and associated tumor types can help predict the genetic or acquired basis of the lesions, and particularly in specimens with no accompanying pertinent clinical history, such potential associations should be suggested in surgical pathology reports.

Renal cystic lesions are usually diagnosed in the radiologists' practice and therefore their characterization is crucial to determine the clinical approach to be adopted and prognosis. The Bosniak classification based on computed tomography findings has allowed for standardization and categorization of lesions in increasing order of malignancy (I, II, IIF, III and IV) in a simple and accurate way. The present iconographic essay developed with multidetector computed tomography images of selected cases from the archives of the authors' institution, is aimed at describing imaging findings that can help in the diagnosis of renal cysts.

Lung Cancer Diagnosis

Background: Lung cancer diagnosis has been a challenge in western Kenya due to the technicalities related to screening and diagnostic procedures. The burden in the adult population is largely unknown, as most patients are managed for Pulmonary Tuberculosis, since both have similar clinical manifestations. The Eldoret Cancer Registry (ECR) provides statistics and epidemiologic profile across western region of Kenya. Aim: The aim of this study is to establish lung cancer incidences in relation to year of diagnosis, age, gender and stage at diagnosis across western Kenya region. Methods: A retrospective review of all cases of lung cancer disease diagnosed at Moi Teaching and Referral Hospital from 2012 to 2016 were identified from the ECR. Data on year of incidence, age, gender, stage at diagnosis and county of origin was analyzed Results: Out of the 60 patients diagnosed with lung cancer, the findings were as follows: In 2012 there were 11 cases representing 18.3%, 2013 10 cases (16.7%), 2014, 12 cases (20%), 2015 12 cases (20%) and 2016, 15 cases (25%). Incidences by age were in the following cohorts; 0-27 years 1 case representing 1.7%, 30-39 years (4) 6.7%, 40-49 years (8) 13.3%, 50-59 years (17) 28.3%, 60-69 years (12) 20%, 70-79 years (15) 25%, above 80 years (3) 5%. Incidences by gender: male had 38 cases at 63.3% and female had 22 cases at 36.7%. Incidence by stage at diagnosis; stage iv (6) 10%, unknown stage (54) 90%. Conclusion: 2016 had the highest incidence and may be associated with the increased awareness on screening services at MTRH. Most cases were between 50-79 years and could be attributed to the slow disease progression and delays in early diagnosis. Higher incidences were in males and may be related to susceptibilities to risks factors such as smoking and industrial fumes respectively. There's need for early diagnosis and disease staging as most cases were at stage 4 and unknown.

PURPOSE: Contrast-enhanced-ultrasound (CEUS) has been frequently used in assessment of cystic renal lesions. OBJECTIVE: The aim of this study was to investigate the Bosniak classification in CEUS compared to CT and MRI in a multi-center setting. METHODS: Bosniak classification in CEUS examinations of cystic renal lesions were compared to imaging findings in computed-tomography (ceCT) and magnetic-resonance-imaging (ceMRI). Imaging results were correlated to histopathological reports. All examinations were performed by experts (EFSUMB level 3) using up-to-date CEUS examination-protocols. RESULTS: Overall, 173 cystic renal lesions were compared to subgroups CT (n = 87) and MRI (n = 86). Using Bosniak-classification 64/87 renal cysts (73.6%) were rated equal compared to CT with upgrade of four lesions (4.6%) and downgrade of 19 lesions (21.8%) by CT (Intra-class-correlation [ICC] coefficient of 0.824 [p < 0.001]). CEUS compared to MRI, presenting different scoring especially in classes Bosniak IIF (n = 16/31) and Bosniak III (n = 16/28) with an ICC coefficient of 0.651 (p < 0.001). CONCLUSION: CEUS can visualize even finest septal and small nodular wall enhancement, which may result in an upgrade of cystic lesions into a higher Bosniak class compared to CT or MRI. Thus, a modification of the Bosniak classification on CEUS may reduce unnecessary biopsies and surgery.

– The authors describe a case of voluminous multilocular cysts of the left kidney in a 41-year-old woman. Potter's dysplatic, Friedman's congenital, Arey's hamartomatose theories have all been put forward regarding the histopathogenesis of this disease. The lack of renal tissue in the septa, the presence of non-communicating compartments containing liquid and the normality of the surrounding parenchyma distinguish this pathology from other cystic lesions of the kidney. Although imaging techniques show the presence of renal lesions, they are not pathognomonic for multilocular renal cysts. The patient underwent left nephrectomy and the histological exam confirmed the diagnosis.

Introduction: Currently, the methods of integrated assessment of patient’s condition based on scoring of separate multidirectional changes in subjective clinical and objective laboratory parameters are used in medical science more and more often. The aim: Based on the identified differences in clinical manifestations and immunological indicators of patients of different age with chronic tonsillitis and patients with no signs of ENT pathology, to develop an integral scoring scale as a basis for an objective assessment of the state of patients with CT and the effectiveness of their treatment. Materials and methods: The clinical signs and immunological factors were evaluated. Patient’s general information, such as age, the presence of allergies, was also taken into account. Based on the analysis of the data array, a scoring system for assessing the clinical and immunological state of patients was proposed. Results: The abnormalities in clinical and immunological assessment in adult population with no signs of ENT pathology (control group) are 2.75 times higher than in healthy children, while in case of chronic tonsillitis the differences between children and adults in terms of integral abnormalities are 1.66 (p<0.05). Conclusions: Integral scoring assessment of clinical and immunological tests makes it possible to provide more objective evaluation of the state of lymphoid tissue of tonsils and the immunity in patients with chronic tonsillitis, which may become an objective basis for choosing patient management strategy, as well as for estimating treatment efficacy.

ABSTRACT: Eleven cases of renal cystadenoma/cystadenocarcinoma-nodular dermatofibrosis syndrome (RCND) are described in German Shepherd dogs diagnosed from January 1994 to January 2018 at the Veterinary Pathology Laboratory of the “Universidade Federal de Santa Maria” (LPV-UFSM). The study sample was composed of eight male and three female dogs at a ratio of 2.67:1. Age ranged from six to 12 years (mean=8.7 years). The main clinical signs reported in descending order of frequency were multiple cutaneous nodules (nodular dermatofibrosis), dyspnea, anorexia, weight loss, recurrent hematuria, vomiting, and polydipsia. Results demonstrated that it is not always easy to clinically recognize this syndrome, but its peculiar anatomical-pathological characteristics allow safe diagnosis. Histologically, it was possible to detect all phases (cysts, papillary intratubular hyperplasia, and cystadenomas or cystadenocarcinomas) of a possible pathological continuum of the renal lesions. Uterine leiomyomas were observed in only one of the cases. Through histochemical techniques, it was possible to identify the presence of type I collagen in both cutaneous and renal lesions and consider its possible involvement in the pathogenesis of renal cystadenocarcinoma. Immunohistochemistry (IHC) showed partially satisfactory results in the staining of epithelial cells of renal cysts and neoplasms for pan-cytokeratin.

Background: This study aims to evaluate the potential benefits of structured reporting (SR) compared to conventional free-text reporting (FTR) in contrast-enhanced ultrasound (CEUS) of cystic renal lesions, based on the Bosniak classification. Methods: Fifty patients with cystic renal lesions who underwent CEUS were included in this single-center study. FTR created in clinical routine were compared to SR retrospectively generated by using a structured reporting template. Two experienced urologists evaluated the reports regarding integrity, effort for information extraction, linguistic quality, and overall quality. Results: The required information could easily be extracted by the reviewers in 100% of SR vs. 82% of FTR (p < 0.001). The reviewers trusted the information given by SR significantly more with a mean of 5.99 vs. 5.52 for FTR (p < 0.001). SR significantly improved the linguistic quality (6.0 for SR vs. 5.68 for FTR (p < 0.001)) and the overall report quality (5.98 for SR vs. 5.58 for FTR (p < 0.001)). Conclusions: SR significantly increases the quality of radiologic reports in CEUS examinations of cystic renal lesions compared to conventional FTR and represents a promising approach to facilitate interdisciplinary communication in the future.

Comparative Review

SummaryCases of cystic bone lesions in horses and humans were reviewed in the literature. These lesions are radiolucent areas of bone, recognized as subchondral cystic lesions in the horse (SCL), intra-osseous ganglia (IOG), subchondral bone cysts secondary to osteoarthrosis (OAC), and unicameral bone cysts (UCB) in humans. Their morphology is quite similar, consisting of lesions with a distinct cyst wall, and a cavity filled with fibrous tissue and yellowish mucoid fluid. The lesions are surrounded by sclerotic bone and can be easily diagnosed radiographically. SCL, IOG and OAC occur in the subchondral bone close to the adjacent joint, whereas UCB occur in the metaphysis of long bones. Their aetiology and pathogenesis is still unknown, although primary damage to the subchondral bone, cartilage or local blood supply and growth disturbances are discussed. In this review 703 lesions of SCL in horses, 289 lesions of IOG and 1460 lesions of UCB in humans were compared in their anatomical location and clinical signs. SCL and OAC resembled each other with respect to anatomical location. A correlation of affected bones could not be found for all four groups. Clinical presentation concerning age was most similar for SCL and UCB with both lesions mainly occurring in young individuals. Gender predominance of males was present in SCL, IOG and UCB. Clinical diagnosis was either incidental, or connected with intermittent pain in all lesions except for OAC. Additionally, the lesions were also found in conjunction with degenerative joint disease (SCL, OAC) or pathological fractures (UCB). Cystic bone lesions were either treated conservatively, surgically with curettage alone, curettage in combination with grafting procedures, or intra-lesional application of corticosteroids. SCL and UCB were similar in their biological behaviour concerning their slow response to the therapy and relatively high recurrence rate. None of the cystic bone lesions were comparable, and a common aetiology and pathogenesis could not be found.In a literature review cases of cystic bone lesions in horses and humans were compared with the goal to find a common aetiology and pathogenesis. Cystic bone lesions occur in horses as subchondral cystic lesions (SCL), and in humans as either intra-osseous ganglia (IOG), subchondral cystic lesions secondary to osteoarthrosis (OAC) or unicameral bone cysts (UCB). IOG and OAC compare with SCL mainly in the anatomical location. IOG and SCL resemble each other in size, clinical signs and histology, whereas UCB and SCL show a similar biological behaviour regarding their therapeutic response and recurrence rate. None of the cystic bone lesions in humans were comparable to the SCL in horses in all aspects. A common aetiology and pathogenesis could not be established.
