title: A case report of atypical magnetic resonance images of the hindfoot following cocaine injection in the foot and a review of osteonecrosis in calcaneus.
abstract: Osteonecrosis in bones with a rich vascular supply, such as the calcaneus, is uncommon. The magnetic resonance imaging (MRI) showed an isolated lesion in the calcaneus in the few cases of calcaneal osteonecrosis reported in the literature. Presented here is a hitherto unreported pattern of multiple serpigenous osteonecrotic lesions in the hindfoot on MRI, in a patient who injected cocaine in his foot.
