Introduction. Teratomas are tumours derived from pluripotent germ cells. They appear most frequently on ovaries. However, other locations are also possible: testicles, retroperitoneum, stomach, neck, and bottom of the mouth cavity. It is not very common to find teratomas in two different body cavities. Case report. A 51-year-old patient visited her doctor complaining of an intensive pain which suddenly appeared in her low back. The computed tomography scan of the abdomen was performed, which revealed cystic formation, 12.5 x 18 cm in size, with remarkable capsule visualization. It had paraaortic, subdiaphragmatic, retropancreatic and suprarenal left localisation with signs of compression and pancreatic dislocation. The cystic formation had a septated appearance filled with clear fluid in all its parts except at the bottom, where it was dense. The intra-operative finding was left retroperitoneal mass placed above the left kidney, dislocating surrounding structures and their infiltration could not be excluded for sure. A tumour mass passed through the diaphragmatic hiatus and continued in the left thoracic space. The cyst was only drained and the fenestration was performed. Three months later, the second operation was performed-splenectomy, left suprarenaladenectomy, left nephrectomy, aortic deliberalisation, the left diaphragmatic crus was opened and tumour mass was completely removed from the thoracic space. The histological examination showed mature teratoma with morphological characterisations of the skin, so the definite diagnosis was dermoid cyst. Conclusion. The patient presented with thoracoabdominal teratoma. Although without malignant transformation, the teratoma required splenectomy, supraadrenalectomy and nefrectomy due to its position and size.

This case represents an incidental splenic cyst misinterpreted as a supernumerary kidney, resulting in a computed tomography scan to confirm the ultrasound (US) findings. A 55-year-old man presenting with renal failure had an US examination which showed a mass adjacent to the left kidney. It resembled a kidney with a dilated collecting system rather than a spleen. Supernumerary kidneys are extremely rare in the published literature. Splenic cysts are more common, but are still relatively unusual. The possible diagnoses and US findings in splenic cysts are discussed.

Study Design: Diagnostic study, level of evidence III. Objectives: Low back pain is a common cause of disability among elderly patients. Percutaneous discoplasty has been developed as a tool to treat degenerative disease when conservative management is not successful. Indications for this procedure include low back pain and the presence of vacuum phenomenon. The objective of this study was to describe a new classification of vacuum phenomenon based on computed tomography scan in order to improve the indications for percutaneous discoplasty. Methods: We developed a classification of vacuum phenomenon based on computed tomography scan images. We describe 3 types of vacuum based on the relationship between vacuum and the superior/inferior endplates and 2 subtypes based on the presence of significant subchondral sclerosis. A validation study was conducted selecting 10 orthopedic residents with spine surgery training to analyze 25 vacuum scenarios. Inter- and intraobserver reliabilities were assessed through the Fleiss’s and Cohen’s kappa statistics, respectively. Results: The overall Fleiss’s κ value for interobserver reliability was 0.85 (95% CI 0.82-0.86) in the first reading and 0.93 (95% CI 0.92-0.95) in the second reading. Cohen’s κ for intraobserver reliability was 0.88 (95% CI 0.77-0.99). Conclusion: The new classification has shown almost perfect inter- and intraobserver reliabilities for grading the vacuum phenomenon and could be an important tool to improve the indications for percutaneous cement discoplasty.

Fibrous dysplasia is a bone disease characterized by an osteoblastic dysfunction resulting in a fibrous replacement of the normal medullary bone. We describe the case of a 33-year-old who presented with low back pain irradiating to her right leg. Both the computed tomography scan and magnetic resonance imaging showed an osteolytic, multicystic lesion of the right hemi-sacrum with invasion of the right S1 foramen. She underwent foraminotomy and curettage of the lesion. Histological diagnosis was fibrous dysplasia, without features of malignant transformation. Three years after surgery the patient is asymptomatic and imaging is stable. This is the fifth known case of monostotic fibrous dysplasia involving the sacrum, a rare entity that must be considered in the differential diagnosis when approaching patients with sacral lesions.

Nephroblastomatosis is a rare preneoplastic lesion defined as the presence of diffuse or multifocal nephrogenic rests. They are divided into 4 categories: perilobar, intralobar, combined, and universal. The aim of this report is to describe a case of diffuse hyperplastic perilobar nephroblastomatosis. A 1-year-old boy presented with an abdominal mass on the left side. Computed tomography scan showed a homogeneous, isointense enlarged left kidney. A fine needle aspiration cytology was reported as Wilms tumor. After chemotherapy, the left kidney was excised. Nephrectomy specimen presented a thick cortical rim of hyperplastic nephrogenic tissue, well delineated from preserved renal parenchyma without pseudocapsule. Nephroblastomatosis is a rare condition affecting renal parenchyma. Diagnosis is based on imaging studies, such as ultrasound, computed tomography scan, and magnetic resonance imaging. Fine needle aspiration cytology is of limited value. Therapeutic management is controversial. Chemotherapy is used preoperatively, and surgical excision may be an alternative for refractory cases.

Abstract Background Teratoma is a tumor derived from fetal germ cells with aberrant differentiation. Case Description A 3-month-old infant with a mediastinal tumor was referred to our heart center. She presented with progressive dyspnea, cyanosis, and the need to be manually ventilated. The computed tomography scan displayed a huge tumor restricting the distal trachea including the bifurcation. An emergent operation was performed and the tumor was completely removed. Histological examination confirmed a mature teratoma. Conclusion In such life-threatening situation, the early detection and the immediate operation are very important for the management of rapidly-progressing mediastinal teratomas compressing the respiratory tract.

Introduction: We present the management of the second reported case of carcinosarcoma of the kidney parenchyma with malignant degeneration of both epithelial and mesenchymal components. Case report: A 36-year-old woman came to our attention for an incidental sonographic finding of a lesion in the lower pole of the left kidney. A contrasted computed tomography scan confirmed the presence of a 50 × 52 mm2 contrasted lesion in the left lower kidney pole. The patient underwent a challenging laparoscopic left partial nephrectomy and para-aortic lymphadenectomy. The histological examination led to the diagnosis of a carcinosarcoma of the kidney parenchyma with malignant degeneration of both epithelial and mesenchymal components. The patient underwent adjuvant chemotherapy with paclitaxel at 175 mg/m2 plus carboplatin area under the curve 6 intravenously for six cycles. At a follow-up of 42 months, the patient is alive and does not show any local recurrences or distant metastases. Conclusion: A multi-disciplinary therapeutic approach, combined with an adequate doctor–patient relationship and a close and detailed follow-up, is of fundamental importance in obtaining good outcomes in such rare and challenging cases.

Hydatid disease is a condition affecting mainly the liver or, to a lesser extent, the lungs. We present an uncommon case of a primary renal echinococcosis in a young man complaining of intermittent hematuria, dull flank pain, and palpable mass in the left lumbar and lateral abdominal area which increases its size over time. After initial self-treatment with painkillers and antibiotics, the patient was referred to a urological clinic, where the physical examination revealed a large tumour mass in the left kidney. Ultrasound showed a large multilocular renal cyst, with a CT highly suspicious for renal echinococcosis (15×12.8×24.2 cm). Serological tests confirmed presence of IgG against Echinococcus. The patient was operated using the lumbar approach and nephrectomy was performed. The man recovered completely after surgery without the need for further treatment.

AbstractCongenital diaphragmatic herniae (CDH) with associated intrathoracic ectopic kidneys are rare congenital anomalies, with a reported incidence of only 0.25%. The authors report a case of a 24-day-old baby girl who was diagnosed with a left-sided CDH on a chest X-ray taken for pneumonia. Computed tomography scan showed CDH hernia, containing small and large bowel and whole left kidney with adrenal gland. Thoracoscopic reduction in the bowel, kidney, and adrenal gland into the abdomen and primary closure of the defect was achieved with no complications. During investigation of the child, it was discovered that her maternal aunt had also had a left-sided congenital diaphragmatic hernia containing the kidney, which was treated via open surgery after birth; she subsequently developed renal cell carcinoma and required radical nephrectomy of that kidney during her third decade.

Adenoid cystic carcinoma (ACC) is a malignancy affecting the salivary glands and rarely involving the lung. Due to its rarity, primary lung ACC remains incompletely understood. We herein report the case of a 57-year-old female patient who was initially diagnosed with primary lung ACC and was treated by lobectomy. Seven years later, an abdominal computed tomography scan performed in the context of surveillance revealed the presence of a solid lesion arising from the lower pole of the left kidney. The patient underwent left partial nephrectomy, and histopathology confirmed a completely excised metastatic ACC.
