Utility of ^99m Tc-MDP SPECT-CT for the diagnosis of sesamoiditis as cause of metatarsalgia

Abstract

Metatarsalgia is a general term for pain in the area of the metatarsophalangeal joints. Sesamoiditis is an uncommon cause of metatarsalgia. It is pain at the sesamoid bones beneath the head of the first metatarsal with inflammation or fracture. The diagnosis is usually clinical, with localized tenderness on palpation. Diagnosing the cause of metatarsalgia in patients without this classical sign is difficult. We present here such a case of a 37-year-old lady in whom sesamoiditis was diagnosed with technetium-99m (99mTc)-methylene diphosphonate (MDP) single photon emission tomography-computed tomography (SPECT-CT).

Hallucal sesamoiditis on a bipartite sesamoid bone: An uncommon cause of chronic great toe pain

“…To the best of our knowledge, no case of hallucal sesamoiditis occurring on a bipartite bone in no-athletic patient has yet been reported. It consists on an inflammatory condition that affects a fragmented sesamoid bone, and is often associated with repetitive stress or trauma to the affected area [3] . Several elements have been reported as predisposing factors [7 , 8] .…”

“…The medial sesamoid bone is located on the inside aspect of the foot, and is commonly bipartite [2] . Sesamoiditis is an inflammatory condition that affects the sesamoid bones, and it is often associated with repetitive stress or trauma to the affected area [3] . The aim of this work is to discuss the clinical and radiological presentation of chronic sesamoiditis occurring on a medial bipartite sesamoid bone.…”
