Surgical resection for accessory spleen torsion: A case report.

Introduction: Accessory spleen torsion is extremely rare, and surgery is often the emergency or elective treatment of choice.

Presentation Of Case: A 20-year-old female with no specific medical history presented to our outpatient clinic with a chief complaint of abdominal pain. The patient was diagnosed with accessory spleen torsion by computed tomography.

A case report of follicular lymphoma arising from the extrahepatic bile duct: interesting contrast-enhanced ultrasonographic findings.

We report a case of follicular lymphoma of the extrahepatic bile duct and the associated characteristic findings of contrast-enhanced ultrasonography (CEUS). A 60-year-old man with jaundice was scheduled to undergo surgical treatment because of a suspected diagnosis of biliary adenocarcinoma. CEUS in the high-resolution power Doppler mode showed early pulsatile enhancement of the inner layer of the thickened bile duct wall.

Portal blood flow via the peribiliary vascular plexus demonstrated by contrast-enhanced ultrasonography with Sonazoid.

Purpose: We report two cases in which portal blood flow via the peribiliary vascular plexus (PBP) was clearly demonstrated using contrast-enhanced intra-operative ultrasonography (CE-IOUS).

Methods: Two patients who underwent hemihepatectomies were investigated using CE-IOUS. Before injection of the contrast medium, both the hepatic arterial and portal venous flows of the hemiliver to be resected were interrupted by ligating those corresponding vessels at the hepatic hilum.

[Two cases of advanced hepatocellular carcinoma (HCC) effectively treated by oral UFT administration].

Case 1 was operated for HCC in September, 2002. After then TAE was performed two times for remnant liver recurrence. A year later, huge recurrence of left liver and tumor thrombus in IVC and PV were detected.

Primary colonic signet ring cell carcinoma presenting carcinocythemia: an autopsy case.

Primary colorectal signet ring cell carcinoma (SRCC) is a rare but distinctive type of mucin-producing adenocarcinoma of the large intestine with still controversial clinicopathological features and prognosis. We encountered primary colonic SRCC in a 51-year-old Japanese man with extensive bone metastasis ultimately leading to carcinocythemia before the initiation of chemotherapy and surgical intervention. Three days before death, besides progressive disseminated intravascular coagulation that had been present on admission, hematological examination showed sudden leukocytosis with nonhematopoietic cells that subsequently turned out to be signet ring cells (SRCs).
