Abdominal ultrasound findings mimicking hematological malignancies in a study of 218 Gaucher patients

Gaucher disease, the most prevalent sphingolipidosis, generally presents with splenomegaly, anemia, and thrombocytopenia, Hence, hematologists are often the specialists involved in diagnosis and management of these patients, We present ultrasonographic characteristics in a cohort of 218 consecutive Gaucher patients evaluated in our clinic during the past 5 years, Our data emphasize the high prevalence of lesions mimicking hematological malignancies in Gaucher disease, One fifth of 184 non-splenectomized patients had intra-splenic lesions, 6% of all patients had similar lesions in the liver, and 32% of 34 splenectomized patients (but none of the other patients) had marked retroperitoneal or peri-portal lymphadenopathy, The presence of splenic lesions correlated with age and splenic size, but not with extent of bone involvement or genotype, Interestingly, they were not affected by reduction in splenomegaly following enzyme replacement therapy, The importance of these findings is to include Gaucher disease in the differential diagnosis of splenic or hepatic lesions, especially in Ashkenazi Jews, Conversely, they are relevant for follow-up of all Gaucher patients, including asymptomatic individuals, because of the reported increased incidence of hematological malignancies in Gaucher disease.
