Rare cause of intestinal obstruction, Ascaris lumbricoides infestation: two case reports.

Ascaris lumbricoides is common resident of intestine especially low socioeconomic areas in the world. Complication of Ascaris lumbricoides has been reported include obstruction of the small intestine, intestinal volvulus and intussusception. We report two children with severe sequelae of intestinal obstruction.

Unusual cause of gastric outlet obstruction: giant gastric trichobezoar: a case report.

Background: Trichobezoars are caused by hair ingestion. The usual presentation of a trichobezoar is with early satiety and malnutrition. Obstructive symptoms and manifestations of gastric outlet obstruction may occur.

[Diffusion-weighted imaging of acute vertebral compression: Differential diagnosis of benign versus malignant pathologic fractures].

Purpose: Our purpose was to assess the value of diffusion-weighted steady-state free precession (SSFP) sequence for differentiating between benign and pathologic compression fractures.

Materials And Methods: Forty-nine patients with 63 acute vertebral compression fractures caused by osteoporosis (n = 23), trauma (n = 7), malignancy (n = 30), infection (n = 3) were examined with a diffusion-weighted SSFP sequence (diffusion gradient strength; 23 mT/m, diffusion pulse length 5 ms), T1-weighted turbo spin-echo sequence, and short-inversion-time (TI 150 ms) T2-weighted turbo inversion recovery sequence. The signal intensity characteristics were analyzed qualitatively and quantitatively for all sequences.
