Small bowel stricture caused by rheumatoid vasculitis.
Small bowel involvement in rheumatoid arthritis is rare and is caused by vasculitis, which results in ulceration, perforation, and necrosis of the small bowel. The authors present a case of rheumatoid vasculitis associated with a small bowel stricture. The patient had a 3-week history of daily postprandial bloating, abdominal cramping, and vomiting. Barium study demonstrated partial small bowel obstruction. Pathologic examination of a resected segment of the small bowel proved that the stricture was caused by rheumatoid vasculitis. To the authors' knowledge, this is the first reported case of such an association in the radiology literature.

Intracardiac extension of intravenous leiomyomatosis.
A 42-year-old woman was found to have intravenous leiomyomatosis of the uterus with extension into the inferior vena cava and right atrium. Intravenous leiomyomatosis is a rare neoplastic disease characterized by invasion of venous channels by a benign smooth muscle tumor arising either from the wall of a vessel or from a uterine myoma. Intracardiac extension is often initially misdiagnosed as a right atrial myxoma and may cause death by mechanical obstruction. The diagnosis of intravenous leiomyomatosis should be considered in young women with cardiac symptoms associated with a right atrial mass who also have a pelvic mass or who have previously undergone hysterectomy because of leiomyoma uteri.

Herpetic esophagitis.
Four patients with herpetic esophagitis were examined. In three of them, the presenting symptom was odynophagia. Early in the course of herpetic esophagitis, shallow round and oval ulcers were seen on barium esophagograms. Later, the ulcers filled with fibrinous exudate, forming nodular plaques that projected into the esophageal lumen. Although these findings are diagnostic of esophagitis, they are not specific for a herpes virus infection. The definitive diagnosis must be established by histologic examination, which demonstrates the cytopathic effect of the herpes virus infection within the squamous epithelium.
