ELEPHANTIASIS NEUROMATOSA: IMAGING FINDINGS
Abstract
A 26-year-old woman with numerous Cafe-au-lait spots at the left leg since birth was presented. Plain radiographs of left leg revealed lobulated enlargement of the soft tissue of left leg from knee to foot, containing no internal calcification. Undertubulation and thickening of the cortex and the periosteum of the tibia and fibula were observed. Osteopenia with multiple extrinsic bone erosions of the tarsal bones was noted. MR imaging showed generalized thickening of the subcutaneous tissue and enlargement of the muscles of left leg, except the tibialis anterior muscle, the tibialis posterior muscle and the extensor hallucis longus muscle. Low signal intensity on T1W sequence and increased signal intensity on T2W sequence of the involved muscles were demonstrated.
