Incremental value of single photon emission tomography/computed tomography in 3-phase bone scintigraphy of an accessory navicular bone

Abstract

Accessory navicular bone is one of the supernumerary ossicles in the foot. Radiography is non diagnostic in symptomatic cases. Accessory navicular has been reported as a cause of foot pain and is usually associated with flat foot. Increased radio tracer uptake on bone scan is found to be more sensitive. We report a case highlighting the significance of single photon emission tomography/computed tomography in methylene diphosphonate bone scan in the evaluation of symptomatic accessory navicular bone where three phase bone scan is equivocal.

Keywords: 99mTc-methylene diphosphonate; Accessory navicular bone; bone scan; single photon emission tomography/computed tomography.

Three phase 99mTc-methylene diphosphonate (MDP) bone scan images. Blood flow (a), blood pool (b) and delayed static (c) images did not reveal any definite abnormal concentration of radio tracer in right foot. Single photon emission tomography (SPECT) (d), computed tomography (CT) (e) and hybrid SPECT/CT (f) images revealing a small bony structure medial to right navicular bone with sclerosis and increased MDP uptake (arrows) which was suggestive of an accessory navicular bone
