SO Annu Conf Australas Soc HIV Med. 1993 Oct 28-30;5:56 (abstract no. FCP3). Unique Identifier : AIDSLINE ASHM5/94349002 AB Skeletal muscle abscesses (pyomyositis) are an uncommon but well recognised problem in human immunodeficiency virus (HIV) patients. This report discusses a case of an ileopsoas abscess in an HIV patient and reviews the experience with HIV associated pyomyositis in patients attending the Royal Melbourne & Fairfield Hospitals. A 29 year old man, with a CD4 count of 110 and extensive bilateral lower extremity Kaposis Sarcoma, (previously treated with radiotherapy and chemotherapy), presented with fever and right hip pain. On CT scanning he was discovered to have a large ileopsoas abscess which was drained percutaneously. Staphylococcus aureus was isolated. There was also evidence of pelvic osteomyelitis. He was treated with a long course of intravenous flucloxacillin. Four other HIV patients presenting to the above mentioned hospitals have had pyomyositis. Staphylococcus aureus was the organism in all cases. All patients had CD4 counts of less than 200. They responded well to drainage and antibiotics. Pyomyositis is uncommon but needs to be considered in HIV +ve patients with unexplained fever and focal pain or swelling.
