The many faces of intraosseous haemangioma: a diagnostic headache.

Intraosseous haemangioma constitutes less than ten percent of all primary bone neoplasms. Approximately 75 percent occur in the calvarium or vertebrae, with long bones, short tubular bones and ribs constituting the rest. We describe a 52-year-old woman who presented with left knee pain for 4-5 years and loss of weight over one week. An initial radiograph of the knee showed several well circumscribed isodense lesions with sclerotic rims in the medullary cavity of the distal femur and diaphysis of the left tibia. There were also lucent lesions with a slightly sclerotic rim in the diaphysis of the left tibia and proximal left fibula. In view of the clinical presentation and radiological findings, extensive investigations were made to rule out metastases and multiple myeloma. An open biopsy with segmental osteotomy of the left mid fibular lesion revealed an intraosseous haemangioma.
