Sports ankle injuries are very common worldwide. In the United States, it is estimated that 2 million acute ankle sprains occur each year, averaging to $318 to $914 per sprain. Magnetic resonance imaging is excellent for depicting normal ankle anatomy and can elegantly demonstrate ligamentous injuries of the ankle and associated conditions after ankle sprain. This article encompasses epidemiology, biomechanics, normal anatomy, and pathologic conditions of the ankle and foot ligaments. The specific ligaments discussed include the syndesmotic ligaments, lateral ligament complex of the ankle, deltoid ligament, spring ligament, ligaments of the sinus tarsi, and the Lisfranc ligament.

Hemorrhage from ectopic gastric mucosa is the most common presenting symptom of Meckel's diverticulum. Diverticular perforation, although rare, is a potentially life-threatening complication. Various imaging modalities can aid in the preoperative detection of Meckel's diverticulum. We report the sonographic findings of a hematocele as the heralding sequela of a perforated Meckel's diverticulum in an 11-month-old boy.
