Avascular necrosis of the hallucial sesamoids is an uncommon cause of metatarsalgia, and the congenital absence of the medial sesamoid is also a rarely reported condition in the podiatric literature. It must be distinguished from other painful conditions of the sesamoid due to the opposite direction of treatment. To our knowledge, there is no reported case of congenital hypoplasia of the medial sesamoid with osteonecrosis. We report a case of nontraumatic metatarsal pains with progressive sclerosis and fragmentation of the medial sesamoid on serial radiographs, magnetic resonance imaging, and ultrasonography with an incidental finding for the absence of contralateral medial sesamoid in a 33-year-old female.
