Aim: To evaluate applicability and efficacy CT vurtual cystoscopy in detection of urinary bladder tumors. Material and methods: During the period of 14 months, 17 patients with suspicion or present of some urinary bladder lesions has undergone CT virtual and conventional cystoscopy. After examination, all data were moved to the workstation for interactive endoluminal navigation. After that, radiologist analyzed transversal and virtual images without results of conventional cystoscopy and made conclusion. Results: Results were divided according to their basic clinical application. By using this method, all lesions over 5 mm in size were revealed. In the group of patients that were followed up for urinary bladder tumors, three patients with carcinomatous lesion were revealed. Two tumors of bladder vault that were missed on transversal scan were visualized by virtual cystoscopy. Useful additional information about tumor spread was given in two patient. One tumor inside the bladder diverticulum was detected, that was not seen by conventional cystoscopy. In two patients, endoluminal origin of mass that could not be confirmed by conventional radiologic methods, was determined. Conclusion: CT virtual cystoscopy is useful method and technique that promise a lot, especially in following situations: a) follow up of bladder tumors; b) supplemental estimation of endoscopically hardly accessible regions; c) differential diagnosis between intravesical and exravesical lesions. Optimal estimation offers adequate bladder distension with patient positioned on the back and on the belly and interpretation as well as on transversal and virtual images. .

Pheochromocytoma of the bladder is a rare bladder tumor. We report a case of an 80-year-old female who presents with recurrent bladder tumors consistent with pheochromocytoma of the bladder, discovered 10 years post-resection of a prior pheochromocytoma of the urinary bladder. She was treated with partial cystectomy and was found to be symp tom free at 6-month follow-up.

Introduction. Although conventional cystoscopy is considered to be the gold standard for diagnosis and follow-up of bladder tumors, it remains an invasive and costly procedure. With the advent of the multidetector CT (MDCT) scanners supported by specialized software virtual cystoscopy (VC) is possible. We assess the role of VC in diagnosing and evaluating bladder lesions.Materials and Methods. Between September 2010 and October 2011, 25 consecutive patients with cystoscopically confirmed bladder tumor underwent VC. The radiologists involved in this prospective study were blinded to the exact findings. After draining any residual urine with a catheter, the bladder was retrogradely insufflated with 200–600 cc of air. No intravenous or intravesical contrast was used. MDCT scan was performed in supine and prone positions and three-dimensional reconstruction of the urinary bladder was performed.Results. The examination was well tolerated by all patients with no complications. In total, 43 lesions were detected both with conventional cystoscopy and VC. Tumor size measured by CT ranged from 3 to 80 mm in diameter. The pathological report revealed noninvasive transitional cell carcinomas in all cases.Conclusion. VC has promising results in detecting exophytic bladder lesions. In the future it could be part of the diagnostic algorithm for bladder tumors.

Background.Retinoblastoma (RB) is a life threatening cancer disease. A breakthrough in the treatment of children with RB is associated with the improvement of conservative treatment that was administered in at least one of the two tumor-affected eyes in most bilateral cases, that was chemotherapy both systemic and local (selective intra-arterial and intravitreal) in most cases combined with laser therapy, cryotherapy, or brachytherapy. The development of such techniques as local chemotherapy is focused on preservation of visual functions, reducing the number of enucleations and radiotherapy (RT) course. The success of the healing of RB is closely associated with a multidisciplinary approach to diagnosis and treatment, as well as specialized longterm follow-up clinical examination.Objective.eye and vision preservation against large intraocular tumors with different growth types and localization without the course of remote radiation therapy was the main purpose.Methods.In the period from September 2012 to January 2016, the study enrolled 45 patients with RB when at least one eye had intraocular tumor spread corresponding to the group C or D. According to the ABC international classification, patients have a relatively good prognosis for organ-preserving treatment. 4 of 18 children with bilateral RB had undergone primary enucleation of worse eye the worst eye, group E; 49 (77.8%) of the 63 affected eyes had features for groups C and D. In this study, no patient received local chemotherapy initially, only after prior systemic chemotherapy. Selective intra-arterial chemotherapy (SIAC) was applied to 41 patients (45 eyes; mean course number was 2), and 32 patients (34 eyes) had undergone intravitreal chemo therapy (IViC) (mean course number was 2). Focal therapy and local chemotherapy were the main methods of treatment for progression (new lesions on the retina) in 8 (16.3%) of 49 eyes with tumors of group C (n=1) and D (n=7); the relapse in 14 of 49 (new lesions on the retina) in eyes with tumors of group C (n=5) and D (n=6) and (new lesions on the retina and the vitreous) in eyes with tumors of group D (n=3) (28.5%), and stabilization of disease n=23 (46.9%). We should note that 2 patients underwent repeated course of in case of systemic chemotherapy, 1 patient — a Gamma Knife procedure due to registered disease stabilization, progression or relapse.Results.10 (20.4%) of 49 eyes saved due to the combined chemotherapy. In 45 patients diseasefree survival rate was 56.1±8.9 % (with mean follow-up period 26.9±2.5 months). 1 of 45 patients died from leukemia. 44 of 45 patients are alive without metastasis. The mean follow-up was 20 months (3 to 43 months). Eye salvage rate in group C — 14 (93.3%) of 15, in group D — 31 (91.2%) of 34.Conclusion.These methods: second line of systemic chemotherapy, RT, and a Gamma Knife procedure should be considered as a failure of primary treatment. Our study demonstrated a high efficacy of local chemotherapy with promissing techniques of conservation therapy, which safety increases due to experience.

Abstract Background Peutz-Jeghers syndrome is an autosomal dominant disease characterized by mucocutaneous pigmentation and hamartomatous polyps in the gastrointestinal tract (GIT). There have also been cases of extra GIT polyps such as the renal pelvis, urinary bladder, lungs and nares. Bladder hamartoma is an extremely rare finding, with only 12 cases described in the literature up to now. The rarity of the condition necessitates a comprehensive compilation of managements up to now so as to provide a better tool for the treatment of such conditions in the future. Case presentation A twenty-year-old male, known to have Peutz-Jeghers syndrome, presented to us complaining of obstructive urinary symptoms. A urethrogram done showed a filling defect at the base of the urinary bladder. The mass was resected transurethrally, and histopathology revealed a hamartoma of the bladder. The patient has since remained tumor-free on follow-up. Conclusions Transurethral resection of the bladder mass proved to be an effective therapy in this patient with no recurrence on the patient’s follow-up till now. There is still, however, a dearth of knowledge regarding the management of bladder hamartomas owing to the extreme rarity of the case.

OBJECT Perineural spread along pelvic autonomie nerves has emerged as a logical, anatomical explanation for selected cases of neoplastic lumbosacral plexopathy (LSP) in patients with prostate, bladder, rectal, and cervical cancer. The authors wondered whether common radiological and clinical patterns shared by various types of pelvic cancer exist. METHODS The authors retrospectively reviewed their institutional series of 17 cases concluded as perineural tumor spread. All available history, physical examination, electrodiagnostic studies, biopsy data and imaging studies, evidence of other metastatic disease, and follow-up were recorded in detail. The series was divided into 2 groups: cases with neoplastic lumbosacral plexopathy confirmed by biopsy (Group A) and cases included based on imaging characteristics despite the lack of biopsy or negative biopsy results (Group B). RESULTS Group A comprised 10 patients (mean age 69 years); 9 patients were symptomatic and 1 was asymptomatic. The L5–S1 spinal nerves and sciatic nerve were most frequently involved. Three patients had intradural extension. Seven patients were alive at last follow-up. Group B consisted of 7 patients (mean age 64 years); 4 patients were symptomatic, 2 were asymptomatic, and 1 had only imaging available. The L5–S1 spinal nerves and the sciatic nerve were most frequently involved. No patients had intradural extension. Four patients were alive at last follow-up. CONCLUSIONS The authors provide a unifying theory to explain lumbosacral plexopathy in select cases of various pelvic neoplasms. The tumor cells can use splanchnic nerves as conduits and spread from the end organ to the lumbosacral plexus. Tumor can continue to spread along osseous and muscle nerve branches, resulting in muscle and bone “metastases.” Radiological studies show a reproducible, although nonspecific pattern, and the same applies to clinical presentation.

Abstract Background: Static 18 F-FDopa PET images are currently used for identifying patients with glioma recurrence/progression after treatment, although the additional diagnostic value of dynamic parameters remains unknown in this setting. The aim of the present study was to evaluate the performances of static and dynamic 18 F-FDopa PET parameters for detecting patients with glioma recurrence/progression as well as to assess further relationships with patient outcome. Fifty-one consecutive patients who underwent an 18 F-FDopa PET for a suspected glioma recurrence/progression at post-resection MRI, were retrospectively included. Static parameters including mean and maximum tumor-to-normal-brain (TBR), tumor-to-striatum (TSR) ratios, and metabolic tumor volume (MTV), as well as dynamic parameters with time-to-peak (TTP) values and curve slope, were tested for predicting: 1) glioma recurrence/progression at 6-months after the PET exam and 2) survival on longer follow-up. Results: All static parameters were significant predictors of a glioma recurrence/progression (accuracy≥94%) with all parameters also associated with mean progression-free survival (PFS) in the overall population (all p<0.001, 29.7 vs. 0.4 months for TBR max , TSR max and MTV). The curve slope was the sole dynamic PET predictor of glioma recurrence/progression (accuracy=76.5%) and was also associated with the mean PFS (p<0.001, 18.0 vs. 0.4 months). However, no additional information was provided relative to static parameters in multivariate analysis. Conclusion: Although patients with glioma recurrence/progression can be detected by both static and dynamic 18 F-FDopa PET parameters, most of this diagnostic information can be achieved by conventional static parameters.
