ABSTRACT We present a case of recurrent carpal tunnel syndrome in a child caused by fibrolipomatous hamartoma of the median nerve which was successfully treated by limited excision of the fibrolipomatous tissue and decompression.

ABSTRACT: To analyze the MR imaging features of fibrolipomatous hamartoma (FLH) of nerves. MR imaging studies from six patients (three men and three women) were retrospectively reviewed by three musculoskeletal radiologists. In four patients, a biopsy of the nerve lesion was performed. In two patients, biopsy data were unavailable and the diagnosis was based on the clinical history combined with the MR imaging findings. MR imaging demonstrated fusiform nerve enlargement that was caused by fatty proliferation and thickening of nerve bundles. Nerve bundles appeared as serpentine tubular structures, hypointense on both T1- and T2-weighted images. The degree of fatty proliferation varied among patients. In addition, significant variation in the distribution of fat along the course of the nerves was noted. In three patients, FLH followed the branching pattern of the nerves, a characteristic pathologic finding. In two patients, intramuscular fat deposition (biceps and tibialis posterior muscles) was present. MR imaging findings of FLH are typical, allowing a confident diagnosis. The variation of fatty proliferation among patients and involved nerves as well as the tendency of the abnormalities to follow the branching pattern of the nerves is well demonstrated with MR imaging. FLH may present as an isolated nerve lesion, may be associated with intramuscular fat deposition, or may occur as a feature of macrodystrophia lipomatosa (MDL).Skeletal Radiology 04/1997; 26(3):155-60. · 1.74 Impact Factor

ABSTRACT: Macrodystrophia lipomatosa is a congenital macrodactyly characterized by proliferation of all mesenchymal components, particularly fibroadipose tissue. We report imaging features of two such patients. MR imaging and CT scanning demonstrated proliferation of fatty tissue in the territory of the median nerve in the hands and forearms, characteristic of macrodystrophia lipomatosa.Radiation Medicine 18(2):129-32.
Article: Imaging of wrist masses.[show abstract] [hide abstract]
ABSTRACT: The wrist is a complex structure with an extensive differential diagnosis for a presenting mass. However, the vast majority of hand and wrist masses are benign, and many of these have a distinctive radiographic appearance. In this article, the imaging characteristics of the most common entities are reviewed with particular attention to magnetic resonance appearance. The 3 most common hand and wrist lesions include ganglion cysts, giant cell tumors of the tendon sheath, and hemangiomas. Other common lesions that can be diagnosed radiographically include lipomas, neural sheath tumors, infection and inflammation, and variant soft-tissue or bony structures. The appearance of the fibrolipomatous hamartoma will also be demonstrated because this is a radiographically distinctive, though rare, lesion.Current Problems in Diagnostic Radiology 01/2004; 33(4):147-60.
