Fibrolipomatous hamartomas of the median nerve are rare, benign tumors characterized by the overgrowth of fibro-fatty tissue within the nerve sheath, often leading to nerve compression. This report presents 2 cases: a 33-year-old man with a gradually enlarging wrist mass and a 48-year-old woman, initially diagnosed with De Quervain's tenosynovitis for radial pain, who was found to have an incidental fibrolipomatous hamartoma on MRI. In both cases, MRI played a pivotal role in diagnosis, revealing characteristic features that enabled a definitive, noninvasive diagnosis. Early recognition of these MRI findings is essential for guiding management and preventing unnecessary surgical interventions.

Introduction: Neural fibrolipoma, also known as fibrolipomatous hamartoma (FLH), is a rare benign tumor that usually affects the upper limb and tends to develop near the n. median. FLH is a rare birth defect defined by the noncancerous growth of fibroadipose tissue around nerve bundles.

Fibrolipomatous hamartoma is a rare benign slow growing fibrofatty tumor of peripheral nerves of unknown etiology. Clinical presentation may mimic carpal tunnel syndrome when involving the median nerve. We present a case of FLH of the median nerve in a 59-year-old female treated with decompression and collagen nerve wrapping.

Background: Lipomatosis of the nerve (LN) is a rare congenital hamartoma in which abundant fibroadipose tissue is found within the epineurium of peripheral nerves. It is frequently associated with nerve territory overgrowth affecting bones or soft tissues. The clinicoradiological features are well known and pathognomonic.
