[Ciliated Muconodular Papillary Tumor of the Lung].

A ciliated muconodular papillary tumor (CMPT) has been reported to be a low-grade malignant tumor or benign tumor, consisting of ciliated columnar cells and goblet cells with basaloid cell proliferation, occur in the peripheral lung. We present a case of CMPT in this report. A 42-year-old male was referred to our department due to a nodule detected in the peripheral left lower lobe of lung.

Management of Ureterolithiasis in a Patient with Crossed Unfused Renal Ectopia.

Crossed renal ectopia is a rare congenital anomaly in which both kidneys are situated on one side and fused together in 85%-90% of cases. The management of urinary calculi in patients with crossed renal ectopia continues to pose challenges to urologists because the aberrant anatomy may make access and clearance of the calculi more difficult to accomplish. Here, we report a case of inferior crossed renal ectopia, without fusion, and a ureteral stone in which the patient was treated successfully by extracorporeal shock wave lithotripsy.

Laparoscopic Management of a Complex Adrenal Cyst.

Adrenal cysts are rare, and their clinical management remains controversial. We report a case involving an adrenal cyst with a complicated appearance on radiological studies. Unenhanced computed tomography revealed a unilocular, noncalcified, hypoattenuating mass with a thin wall in the left adrenal gland.

Inferior vena cava thrombosis associated with a distended ileal neobladder.

Venous stasis is generally accepted to be a predisposing factor for venous thrombosis. However, benign causes of inferior vena cava (IVC) obstruction with associated thrombus formation have not been well described. We herein present a case of IVC compression caused by a distended ileal neobladder measuring 2,000 mL in capacity that led to IVC thrombosis.

Dynamic CT of acute cholangitis: early inhomogeneous enhancement of the liver.

Objective: Our objective was to describe the dynamic CT findings of acute cholangitis, especially early inhomogeneous enhancement of hepatic parenchyma.

Materials And Methods: Inhomogeneous enhancement of hepatic parenchyma was retrospectively evaluated on dynamic CT in 406 consecutive patients without irregular fatty liver or multiple hepatic tumors. Dynamic CT scans were obtained 30 sec (early phase) and 90 sec (late phase) after starting the contrast material injection.
