Figures & data
Figures 1. (a–c) Physical findings: The bilateral overgrowth of the upper extremities occurred, extending from the shoulders to the fingers. Both the length and circumference of the upper extremities increased.
Figures 2. (a–f) Physical findings: The overgrowth of the ring and little fingers, as well as of the palm corresponding to the fourth and fifth metacarpal bones was not obvious in the left hand.
Figures 3. (a,b) CT scans: Any congenital anomalies (e.g., syndactyly) were not found, except the bilateral, disproportional overgrowth of the upper extremities.
Figures 4. (a–d) CT scans: Adipose tissue hyperplasia was salient in the subcutis and intermuscular stroma of both upper extremities, with bilateral macromelia and macrodactyly. The ring and little fingers of the left hand were not enlarged. Muscles and adipose tissue of the thigh were not atrophied or enlarged. The bilateral overgrowth of muscles of the shoulders, the arms, and the proximal forearms was salient. Adipose infiltration was noted in the stroma of the deltoid muscle and brachial biceps. Muscles of the right forearm were atrophied, and atrophy and adipose degeneration were salient in all muscles of the right hand.

Figures 5. (a,b) MRI: MRI showed increased T2 signal in the interior of the median nerve, suggesting the presence of fat. The median nerve was enlarged of both upper extremities. Especially, adipose hyperplasia was salient in the carpal tunnel.
