Intrabiliary metastasis from colorectal carcinoma (CRC) growing within or invading bile ducts is not a very common pattern. However, accurate diagnosis of metastatic lesions is very important for selection of adjuvant therapy and prognosis. We report a case of 71-year-old male who developed painless jaundice due to hepatobiliary obstruction. MRI demonstrated 1.4 cm intraductal mass at hepatic h...

OBJECTIVE to report on the first liver resection performed on a human being by a transvaginal NOTES approach combined with minilaparoscopy. PATIENTS AND METHODS a sixty-one-year-old woman with a history of Wertheim s hysterectomy for endometrial carcinoma 10 years ago, and malignant melanoma correctly treated in 2006, had suspected segment-V liver metastasis near the gallbladder by CT-scan an...

The renal arteries are a pair of lateral branches arising from the abdominal aorta below the level of superior mesenteric artery at the upper lumbar level (L1–L3). These arteries carry about 20% of the cardiac output to supply the organ that is about 1/100 of the total body weight. The right renal artery is longer in its course owing to the location of the abdominal aorta more towards the left ...

BACKGROUND Whether sonography is an appropriate imaging modality for cervical lymph nodes in patients with papillary thyroid microcarcinoma (PTMC) remains unclear. Hence, this study aimed to evaluate the diagnostic value of ultrasonography (US) features for lymph node metastasis in PTMC. METHODS Seven hundred twelve patients with PTMC who underwent conventional ultrasonography examinations of...

The presence of pancreatic islets alone in the peripancreatic region and splenic hilum is an uncommon occurrence. Herein, we describe their presence in this rare location.

BACKGROUND Preoperative determination of the aetiology of bile duct strictures at the hilum is difficult. We evaluated the diagnostic accuracy of laboratory parameters and imaging modalities in differentiating between benign and malignant causes of hilar biliary obstruction. PATIENTS AND METHODS Fifty-eight patients (26 men) with a history of obstructive jaundice and liver function tests (LFT...

Radiol Bras. 2015 Nov/Dez;48(6):399–403 401 http://dx.doi.org/10.1590/0100-3984.2015.0119 ing from sequelae, generally associated with tuberculosis. The occurrence of lung cancer in cavities mimicking fungus ball or air crescent sign is quite rare. The tumor tends to infiltrate in the adjacent pulmonary parenchyma causing a paracicatricial effect, and may lead to emphysematous or cystic changes...

Introduction A single renal artery to each kidney is present in approximately 70% of individuals. Renal arteries take origin from the aorta bilaterally just below the superior mesenteric artery. The arteries vary in their level of origin and obliquity. Near the renal hilum each artery divides into an anterior and a posterior division which divide into segmental arteries supplying the renal vasc...

A 33-year-old man with chronic alcoholism presented with recurrent episodes of hematemesis and melena over an 18-month period. He had received about 20 units of packed red blood cells (PRBC). Upper gastrointestinal (GI) endoscopy performed elsewhere showed large esophageal varices and gastric varices (GOV2F2) for which three sessions of endoscopic sclerotherapy and glue injection had been perfo...

Hemangiomas are slowly growing benign vascular tumours which rarely involve the kidney. They usually occur in the mucosa or subepithelial tissue of the pelvis, in the pyramid of the kidney and in the cortex. We report a case of cavernous hemangioma presenting as a solid, paradoxically avascular mass of the right renal hilum.
