Cervical spinal arteriovenous malformation.

Cervical spinal arteriovenous malformations and fistulas are rare but important entities because they are potentially curable. MRI and angiography are the most useful imaging modalities for the diagnosis. On contrast-enhanced CT imaging, they can mimic a tumor.

Transition of renal arteriovenous fistula to arteriocalyceal fistula during embolization.

Selective and superselective renal embolization is a generally accepted technique for treating traumatic or iatrogenic renal arteriovenous fistulas or arteriocalyceal fistulas. Only a minority are pure arteriocalyceal fistulas. During embolization, an arteriovenous fistula may become a frankly bleeding arteriocalyceal fistula, causing massive haematuria and necessitating further embolization.

Esophageal cancer.

The authors invited eminent Belgian specialists to report on their experience in esophageal cancer. A summary is given of the most striking features of their reports.

Fibrous mesothelioma. Case report.

A case of fibrous mesothelioma is presented. Chest films suggested an elevation of the left diaphragm and a limited pleural effusion, which was confirmed on computed tomography. Percutaneous needle biopsy showed mesothelial cells.

Rectal cancer: a summary.

The authors summarize the most important conclusions of a multicentric multidisciplinary review on rectal cancer in Belgium.

Transluminal angioplasty: late results sustained by digital intravenous subtraction angiography.

Digital intravenous subtraction angiography (DIVSA) appears to be a technique of minimal invasiveness and high accuracy in the follow-up of patients after percutaneous angioplasty (PTA) allowing correct angiographic evaluation in more than 96% of the cases. Correlation between clinical and angiographic findings seems to be excellent. Of the controlled intravenous examinations performed in 54 successful PTA procedures 75% appeared patent after 10 to 30 months, constituting 52% of the original attempts.

Computed tomography of muscle.

Computed tomography (CT) scans of skeletal muscles of 3 patients with pseudohypertrophic muscular dystrophy are presented. Different patterns of muscle alterations and particularly of pseudohypertrophy are described. The significance of the radiological findings for clinical examination, electromyography, and needle biopsy is discussed.

Computed tomography of the normal and pathologic muscular system.

A standard program of computed tomographic (CT) scanning of the human skeletal muscular system was developed. Scans were obtained on five levels: the neck, the shoulder girdle, the pelvic girdle, the thigh, and the lower leg. The normal size and density of several muscles were determined.
