Ascariasis Presenting as Hematoma in the Sigmoid Mesocolon: A Case Report.

Ascariasis is an intestinal disease caused by Ascaris lumbricoides. Most patients with ascariasis are asymptomatic; however, the presence of many larvae in the bowel can cause gastrointestinal complications, such as intestinal obstruction, obstructive jaundice, cholangitis, cholecystitis, and pancreatitis. Herein, we report a case of ascariasis presenting as hematoma and active bleeding in the sigmoid mesocolon of a 74-year-old man on computed tomography (CT). Sigmoid colon perforation was also detected on follow-up CT. Laparoscopic low anterior resection was performed; there was a large hematoma in the sigmoid mesocolon. Roundworms were microscopically identified in the mesenteric adipose tissue. The clinical and CT findings of this unusual presentation of ascariasis revealed serial complications during parasite migration from the intestinal lumen to the peritoneal cavity.

Unusual meandering right upper lobe pulmonary vein draining into right middle lobe pulmonary vein: a case report.

Meandering right pulmonary vein is a rare vascular anomaly that requires accurate diagnosis to avoid unnecessary procedures and unintended vascular injury during operation. We describe an unusual meandering right upper lobe pulmonary vein draining into the left atrium via the right middle lobe pulmonary vein.

Assessment of hepatic function with Gd-EOB-DTPA-enhanced hepatic MRI.

Assessment of hepatic function is essential in determining the prognosis and clinical management of a patient who has chronic liver disease or undergoes liver surgery. For a patient with locally varying hepatic parenchymal abnormalities, a regional assessment of hepatic function mapped onto hepatic anatomy is clinically more meaningful than conventional global metrics of hepatic function. Of late, hepatic magnetic resonance imaging has been increasingly used because of its superb tissue contrast and delineation of hepatic morphology and underlying abnormalities. The introduction of hepatocyte-specific contrast agents such as Gd-EOB-DTPA allows us to view not only the hepatic anatomy but also assess regional hepatic function. In this article, we review and discuss recently published studies that used Gd-EOB-DTPA-enhanced magnetic resonance imaging to evaluate hepatic function.

Bilateral accessory inferior turbinates and secondary middle turbinates.

Bifid inferior nasal turbinates-two inferior turbinates with a single root observed in the nasal cavity-are an extremely rare anatomical variation, especially when they are observed bilaterally and exist with other variations. We report a case of bilateral bifid inferior nasal turbinates with bilateral secondary middle turbinates. We discuss the findings of this rare condition and suggest an appropriate term-accessory inferior turbinate-to replace bilateral inferior turbinate by reason of its embryology.
