Abstract
IntroductionIntra-articular osteochondroma and acoustic neuroma are rare entities.Case presentationWe report the rare occurrence of a para-articular osteochondroma of the knee developing over short duration, 5 months, following minor injury.ConclusionPredisposition to heterotrophic ossification after previous neurosurgery and a second acoustic neuroma may have accelerated the growth of this benign tumour. The development of these two rare entities suggests they may be associated.

Summary
Anterior knee pain is a common symptom and may be caused by pathology found in the patellofemoral joint or the infrapatella fat pad. A sixty-one year old gentleman complained of two-day history of increased pain and swelling of his right knee. Five months earlier he had sustained a twisting injury to his knee while playing golf. Following the injury he was able to complete his game and there was minimal swelling He was aware of a continued dull ache to the front of his knee which was worse on going up and down stairs. The increased bright signal on T2 shows the cartilage within the osteochondroma and oedema within the fat pad. The lesion was 45 mm in diameter, and had been completely excised On microscopic examination it was composed of acellular dense hyalinised fibrocollagenous tissue with evidence of focal ossification, cartilaginous metaplasia and calcification. The fat pad has high signal on the T1 image
