Mycotic aneurysm--a rare complication of acute osteomyelitis in a child. A case report.

A case of mycotic aneurysm formation of the right iliac artery is described. This unusual complication developed as a result of acute osteitis of the left tibia which was initiated by a kick on the lower leg. One month after treatment for osteitis of the tibia, the patient was readmitted because of unequivocal evidence of ischaemia of the right leg and a large pulsatile mass in the right iliac fossa, confirming the clinical diagnosis of mycotic aneurysm. The aneurysm was excised but because the wall of the artery was extremely friable simultaneous revascularization was deferred for fear of uncontrollable haemorrhage from the anastomotic line.
