Teratomas are rare germline tumors that originate from embryonic germ cell layers. Teratoma of the kidney is extremely rare. We report the main radiologic features of an unusual case of mature cystic teratoma arising from the right kidney in a two-year-old boy. A left-sided abdominal mass was detected on physical examination and B-Mod Ultrasound (US) examination revealed a heterogeneous mass with central cystic component. Nephrectomy was performed and a large, fatty mass arising from the right kidney was excised. The final pathologic diagnosis was confirmed as cystic-solid renal teratoma.

Isolated iliac aneurysms are rare, and their management becomes complex when accompanied by ectopic pelvic kidneys due to altered vascular anatomy. We report a 58-year-old male with an incidentally discovered 53.5 mm left common iliac artery (CIA) aneurysm and an ectopic pelvic kidney.

Malignant rhabdoid tumor is a rare highly aggressive neoplasm that affects young children. It is composed of stromal and epithelial components and commonly arises from the kidney. The clinical presentation is usually nonspecific, and the common signs are palpable abdominal mass, hematuria, fever, anemia, and hypercalcemia.

Recently, new findings have been clarified concerning both pathogenesis and treatment of IgA nephritis. The four hits theory has been confirmed but several genetic wide association studies have allowed finding several genes connected with the pathogenesis of the disease. All these new genes apply to each of the four hits.

Hyperchloremic metabolic acidosis is a known complication following ileal conduit urinary diversion, often arising from urinary reabsorption in the ileum, which leads to chloride retention and bicarbonate loss and, though often asymptomatic, can produce clinically significant symptoms, particularly in patients with underlying renal impairment. A 75-year-old woman with a history of bladder cancer underwent cystectomy with ileal conduit diversion and presented on postoperative day 47 with anorexia, hypotension, and weight loss; laboratory findings revealed hyperchloremic metabolic acidosis with elevated serum chloride. The patient's acidosis gradually improved with sodium bicarbonate and Ringer's solution, stabilizing her blood pressure, creatinine, and acid-base balance, and she was discharged with outpatient follow-up.

Autosomal dominant polycystic kidney disease (ADPKD) is a common genetic disorder leading to end-stage renal disease. ADPKD arises from mutations in the and genes, which encode polycystin 1 (PC1) and polycystin 2 (PC2), respectively. PC2 is a non-selective cation channel, and disease-linked mutations disrupt normal cellular processes, including signaling and fluid secretion.
