Fibrolipomatous Hamartoma of the Median Nerve: MRI & CT Scan Diagnosis, Radiology Interpretation, and Best Treatment Guide for Rare Imaging Cases
Introduction A 35-year-old man presents with progressive wrist pain, swelling in the palmar wrist, and intermittent numbness. Initial concern may include a ganglion cyst, nerve sheath tumor, or tendon pathology. However, advanced medical imaging reveals a far rarer diagnosis: Fibrolipomatous Hamartoma (FLH) of the median nerve. This uncommon benign lesion is one of the most fascinating entities in radiology interpretation because it often demonstrates pathognomonic MRI findings that allow diagnosis without biopsy. For clinicians, radiologists, orthopedic surgeons, and imaging professionals, understanding FLH is crucial because it can mimic more aggressive pathology while requiring a very different management strategy. In this comprehensive guide, we review: Pathophysiology Epidemiology Clinical presentation MRI, CT scan, diagnosis , X-ray, and ultrasound findings Differential diagnosis Stepwise diagnostic workflow Treatment strategies Prognosis Quiz section for learning retent...
