ABSTRACT: Tarsal navicular stress fractures are injuries more commonly observed in athletes involved in sprinting and jumping sports. Known risk factors for the development of navicular stress fractures include pes cavus, metatarsus adductus, limited subtalar or ankle motion, medial narrowing of the talonavicular joint, as well as a short first metatarsal. The presence of an os supranaviculare has yet to be described as a predisposing factor in the occurrence of navicular stress fractures. We present two cases of navicular stress fractures in patients with an os supranaviculare and discuss possible reasons for such an association.

ABSTRACT: Lead poisoning from gunshot wounds is unusual. Awareness of this rare but serious complication can guide the physician in making a prompt diagnosis. We present a case of a 30-year-old male who had a remote history of a gunshot wound in the right knee and presented with right knee pain. Plain film showed intrarticular invasion of the bullet fragments. He was also found to have microcytic anemia with high blood lead levels. Chelation therapy was immediately started, followed with surgical removal of the bullet fragments. Lead intoxication is a rare but fatal complication of gunshot wounds. After a timely diagnosis, chelation therapy should be immediately started.

ABSTRACT: Intraosseous lipoma is an uncommon entity that presents almost exclusively as a solitary lesion. Multiple intraosseous lipomas are exceedingly rare with only a few cases being reported in the literature.
We present a case of 43-year-old African American female who presented with left leg and left wrist pain. The initial radiographs revealed well-defined radiolucent lesions in multiple bones involving the left wrist and the left lower limb. The magnetic resonance demonstrated multiple lesions, which showed high signal on the T1 and low signal on the fat suppressed T2 images. This favored the diagnosis of intraosseous lipomatosis that was confirmed by biopsy.
Multiple intraosseous lipomatosis is an uncommon but important differential for multiple radiolucent lesions on the plain radiographs. This condition can lead to pathological fractures. Magnetic resonance imaging can aid in providing an accurate diagnosis. The awareness of this condition can help the clinician in guiding the correct diagnosis and management.
