Large papillary thyroid cancer bed recurrence causing overlying skin ulceration and bleeding.

Undifferentiated shock in a cirrhotic patient: Ascites matters.

In cirrhotic patients with undifferentiated shock, early CT with emphasis in ascitic fluid density should be performed to exclude rare causes of shock such as secondary peritonitis or hemoperitoneum.

Difficult diagnosis of an air-containing, abscess-like, and mass-like pancreatic head lesion.

Duodenal diverticulosis can be a difficult CT diagnosis and should be considered in the differential diagnosis when a periduodenal mass-like structure that may contain air, air-fluid level, or oral contrast material is depicted.

Procedure of choice in a patient initially operated for a suspected epithelial appendiceal neoplasm.

In patients operated for a suspected appendiceal neoplasm, radical appendectomy is the procedure of choice because it provides definitive treatment in most of appendiceal neoplasms, except from mucinous or colonic-type adenocarcinoma and NET>2 cm.
