Melorheostosis of the left foot AR Online

Description: A 47-year-old male presented with a history of left foot pain, discomfort, difficulty standing and walking, and a sensation of “walking on marbles” for several months; he also was unable to fit his foot into his shoe. The patient’s past medical history was significant for left foot sesamoiditis and remote surgical procedures on the left foot. A plain radiograph of the left foot showed mixed sclerosing dystrophy in addition to a “candle-wax-like” appearance and thickening of the cortices of the calcaneum, third through fifth metatarsals, and proximal phalanges. An MRI scan showed signal alteration and hypointensity on both T1- and T2-weighted sequences. A three-phase bone scan with Tc-99m-MDP scintigraphy demonstrated moderately intense uptake of the radiopharmaceutical localized to the left lateral foot, which corresponded to the sclerosing lesion seen on the plain radiographs and MRI.
