Neural fibrolipoma of the median nerve

We report a rare case of neural fibrolipoma [lipofibromatous hamartoma] of the median nerve of the hand. An 18-year-old male complaining of progressive and chronic macrodactyly of his thumb of the left hand, with neurological complaints, was admitted to the hospital. Magnetic resonance [MR] evaluation revealed fibro-fatty infiltration of the median nerve at the level of the carpal tunnel, and the terminal branches of the median nerve in the thumb and index. The pathological examination of excised tissue confirmed the diagnosis of neural fibrolipoma of the terminal branch of the median nerve in his thumb. Imaging is recommended; MR studies on morphological abnormalities must be done in similar cases
