Fibrolipomatous Hamartoma of Digital Branch of the Median Nerve without Macrodystrophy: Two Case Reports with Magnetic Resonance Imaging Findings

Fibrolipomatous Hamartoma of the Median Nerve

A case of fibrolipomatous hamartoma of the median nerve is presented. The operative findings were characteristic. The diagnosis should be confirmed by histological examination of a biopsy from an involved palmar cutaneous branch, and treatment should be limited to decompression of the ligament or fascia over the involved area.

Fibrolipomatous hamartoma of the median nerve

http://www.sajr.org.za doi:10.4102/sajr.v19i2.886 Fibrolipomatous hamartoma is a rare benign tumour most commonly affecting the median nerve and is characterised by fibro-fatty nerve infiltration. It results in fusiform nerve enlargement with a pathognomonic ‘spaghetti-like’ imaging appearance. Patients present with numbness and paraesthesia and later with motor deficits in the affected nerve d...

Fibrolipomatous hamartoma of the median nerve on CT

Fibrolipomatous hamartomas are rare lesions with a pathognomonic appearance on MRI. I describe CT findings that parallel the pathognomonic description on MRI. While these lesions are typically evaluated on MRI, they may be discovered incidentally on a CT scan of the upper extremity. In addition, contraindications to MRI may require CT evaluation in some cases. The findings of soft tissue with c...

Fibrolipomatous hamartoma in the median nerve in the arm - an unusual location but with MR imaging characteristics: a case report

Fibrolipomatous hamartoma of the median nerve are usually located distally in the forearm and may have characteristic features on MR imaging. Here we report a patient with an extensive fibrolipomatous hamartoma at an unusual location proximally in the arm, where a preoperative MR imaging was pathognomonic and diagnosis was verified by an incisional biopsy. We suggest that MRI should be performe...
