title: Uremic leontiasis ossea.
abstract: Uremic leontiasis ossea is a rare manifestation of renal osteodystrophy clinically characterized by jaw enlargement, widening of the nares, flattening of the nasal bridge, and increased interdental spacing. Computed tomography (CT) findings are particular characteristic and include serpiginous tunneling within the maxillofacial bones and cortical bone resorption. Nuclear medicine scans are also useful for demonstrating hyperplasia of the parathyroid glands. Ultimately, the diagnosis of uremic leontiasis ossea can be made non-invasively through a combination of clinical parameters and imaging findings, as described in this article.
