Ultrasonographic Diagnosis of Lipofibromatous Hamartoma of the Median Nerve (Case Report)
نویسندگان
چکیده
Lipofibromatous hamartoma (LFH) is an extremely rare benign tumor, which is characterized by an excessive infiltration of the epineurium and perineurium by fibroadipose tissues. A 27-year-old woman was diagnosed with left carpal tunnel syndrome (CTS) due to LFH of the median nerve. LFH was diagnosed by MRI and sonography; the characteristic ultrasonographic feature of LFH showed a good correlation with pathognomonic MRI findings. The median nerve was involved along its course in the forearm; however, the patient needed carpal tunnel release because of severe compression of the median nerve under the flexor retinaculum.Radiologic evaluation of patient with CTS to evaluate probable secondary CTS is recommended.

This report describes a rare case of secondary carpal tunnel syndrome due to a lipofibromatous hamartoma of the median nerve. Excision of the fibrofatty tissue between the nerve fascicles without risking damage to the fascicles was impossible. The transverse carpal ligament was incised and an epineurotomy was performed. Within six months, the 25-year-old female patient's symptoms were much impr...
متن کاملLipofibromatous hamartoma of the digital branches of the median nerve presenting as carpal tunnel syndrome: A rare case report with review of the literature.
Lipofibromatous hamartoma (LFH) is a rare, benign fibrofatty tumor composed of a proliferation of mature adipocytes within peripheral nerves, which form a palpable neurogenic mass. It affects the median nerve in 66-80% of cases, causing pain and sensory and motor deficits in the affected nerve distribution. Patients typically present with gradually enlarging nontender lesions in the distributio...
متن کاملLipofibromatous hamartoma of the median nerve
Lipofibromatous hamartoma is a rare tumor-like overgrowth of fibroadipose tissue surrounding the nerves. Most commonly, it involves the median nerve. The tumor is usually present at birth and grows very slowly. The expected age of clinical presentation is the third or fourth decades of life. The case reported here had a rapid overgrowth and presented at the age of eight. Our case is the first r...
