Intrapelvic mass causing femoral compression neuropathy in a patient with Gaucher disease: a case report.

Gaucher disease is a lysosomal storage disorder in which glucocerebroside accumulates within the macrophages in any part of the body. Varying degrees of skeletal involvement may occur besides anemia, coagulation abnormalities and hepatosplenomegaly. Most of the factors influencing the quality of life in a patient with Gaucher disease are related to bone involvement. Gaucher cell deposits may extrude through cortical erosions and cause soft tissue masses around bones which are involved by the disease. We present a 38-year-old female patient with Gaucher disease who had a large intrapelvic mass originating from left iliac bone causing femoral compression neuropathy. The classification of disease is based on neurological involvement and if symptoms exist whether the symptoms are acute or subacute. The neurological impairment caused by compression by a tumor should be distinguished from the ones reported in neurogenic forms of the disease.
