Pseudothrombosis of the right ovarian vein. Pitfall of abdominal spiral CT.

We present the computed tomography (CT) findings of pseudothrombosis of the right ovarian vein. In two young multiparous women, pseudothrombosis was detected on early-phase spiral CT scans by the presence of retrograde flow of contrast medium down the left ovarian veins. Asymmetry of density seen in the ovarian veins in the early phase of spiral CT scanning related to reflux in the left ovarian vein should not be mistaken for right ovarian vein thrombosis.

Intracranial bullet migration--a sign of brain abscess: case report.

An unusual case of migration of an intracranial bullet fragment within a brain abscess is reported. Movement of the bullet was first detected on skull films, and the significance of this finding on plain radiographs is emphasized.

Chronic venous insufficiency: assessment with descending venography.

Six hundred forty-four legs were examined by means of descending venography in patients with chronic venous insufficiency. Three patient positions (supine, 30 degrees semierect, and 60 degrees semierect) were used with a standard angiographic technique. Patients were also studied during either normal respiration or a Valsalva maneuver. The deep venous valvular system was incompetent more often than the superficial (saphenous) venous system. Positive venograms revealed that reflux occurred into the deep venous system alone in 82%, the superficial venous system alone in only 2%, and a combination of deep and superficial systems in 16%. The authors conclude that descending venography is best performed at the more physiologic 60 degrees semierect position and with the Valsalva maneuver, which enables evaluation of the competence of valves in the closed position.

Radiological seminar CCXLXIII: percutaneous gastrojejunostomy--a interventional radiologic procedure.

The authors describe the recent emergence of an interventional radiologic procedure, percutaneous gastrostomy and gastroenterostomy. They present a case report, and discuss indications, methods, and advantages of the procedure for some patients.

Radiological seminar CCXLXII: CT of adrenal gland pheochromocytoma.

Herein, we have described our experience with CT and pheochromocytomas arising from the adrenal gland over a recent six year period. In all of our patients who underwent CT scanning, localization of the tumor was successful. CT remains an accurate means for localization of adrenal pheochromocytomas.

CT of adult adrenal cortical carcinoma: six years experience.

During 1980 and through 1985, a total of three adult patients with adrenal cortical carcinoma were patients at the University of Mississippi Medical Center. All three of these patients with large tumors were evaluated with CT abdominal scans. The CT findings are described in each case. One patient had the unique findings of four separate tumors at the left upper quadrant, i.e. an adrenal cortical carcinoma, an ipsilateral renal cell carcinoma, an adjacent para-aortic neurofibroma, and a gastric leiomyoma. The only known cure for adrenal cortical carcinoma is complete excision. CT scanning should be utilized in all cases for diagnosis, for characterizing the tumor, for showing the presence of metastatic disease, for determining the overall extent of disease, and for determining the relationship to other organs. CT should be utilized in the follow-up with these patients after treatment, i.e. surgery and/or chemotherapy.

Bilateral popliteal arteriovenous fistulas.

An unusual case of bilateral popliteal arteriovenous fistulas is reported. The patient reported right leg discomfort and swelling 1 month after multiple gunshot wounds to both legs; the left leg was asymptomatic. Arteriography demonstrated AV fistulas in both popliteal arteries. The importance of a high index of suspicion in making the diagnosis is emphasized.

An alternative method for repair of a leaking arterial chemotherapy infusion catheter.

Regional chemotherapy infusion via selective arterial catheterization is frequently complicated by the development of cracks or leaks within the catheter. This frequently necessitates a catheter exchange. Herein, we report an alternative, simpler method for dealing with a defect within an infusion catheter.
