Primary and metastatic tumors of the liver can be treated successfully with transcatheter chemoembolization (TACE) during selective arterial catheterism. Arteritis is a possible referred side effect which can lead to tortuosity of the arteries, stenosis and occlusion of vessels. In our hospitals 117 consecutive patients were treated with TACE from January 1990 to December 1992; 61 patients were affected by hepatocellular carcinoma (HCC) and 56 were affected by metastases from colorectal carcinoma. Each patient received from 1 to 4 treatments at monthly intervals using epirubicin/Lipiodol ultrafluid (E/LUF) or a mixture of epirubicin and mitomicin C (MC)/LUF and followed by gelatine sponge injection in the hepatic artery. Selective angiography performed 30-62 days after the first chemoembolization showed artery stenosis in 7 patients and thrombosis in 2 cases related to toxic arteritis due to chemoembolization. Reports about arteritis during TACE treatments are discussed.

Tropical pyomyositis is an infection of muscles mainly presenting in black people, occurring in the trunk and limbs. At Hoima Hospital, Uganda, 58 patients (30 men and 28 women) with a mean age of 21 years have been investigated by ultrasound; a total of 81 lesions were present. Two different characteristic images were found; abscess was present in 65 cases while 16 patients showed a diffuse infiltration among the muscular fibers. These two different images correspond to the two stages of histologic and clinical progression described by other authors. Ultrasound is useful to demonstrate the progression of pyomyositis and to determine when and where to drain any abscess.
