Case Reports
Emphysematous pyelonephritis with resultant emphysematous cholecystitis secondary to hematogenous dissemination.
Both emphysematous pyelonephritis and emphysematous cholecystitis are uncommon, but potentially fatal, clinical entities. The simultaneous diagnosis of these two entities in the same patient has not previously been reported. ⋯ Additionally, the unique circumstances of this case offer support for the proposal that emphysematous cholecystitis may often be secondary to hematogenous seeding/embolic phenomena rather than obstruction of the cystic duct. Prompt diagnosis is essential, as prompt intervention can minimize mortality and morbidity.

Case Reports
Nonpalpable rectus sheath hematoma clinically masquerading as appendicitis: US and CT diagnosis.
Within a period of 5 years, we encountered three patients with a small rectus sheath hematoma, presenting with clinical signs of appendicitis. The rectus sheath hematoma was diagnosed by ultrasound (US) in all three cases and confirmed by computed tomography (CT) in two. ⋯ In patients who are sonographically examined for suspected appendicitis, the abdominal wall should be studied as well, to exclude a nonpalpable rectus sheath hematoma. In cases in which a hematoma is found, an unnecessary appendectomy can be prevented.

The purpose of this study was to determine the magnetic resonance (MR) features of intrahepatic cholangiocarcinoma. ⋯ The typical MR appearance of intrahepatic cholangiocarcinoma is a large well-delineated nonencapsulated tumor associated with intrahepatic venous encasement.
