Sonographic detection and characterization of musculoskeletal and subcutaneous tissue abnormalities in sickle cell disease.
Pain due to bone marrow infarction is common in homozygous sickle cell disease (SS disease). Musculoskeletal pathology may be responsible for persistent atypical symptoms. We have assessed the frequency and ultrasound appearances of soft tissue and joint abnormalities in SS disease. SS disease patients with atypical musculoskeletal symptoms were examined with ultrasound over a 2 year period. Ultrasound findings were correlated with those at surgery or percutaneous drainage. 31 episodes in 23 patients were referred for ultrasound. There were 36 abnormalities in 18 patients: abscess (n = 15), effusions (n = 5), soft tissue induration (n = 12), fat necrosis (n = 2), haematoma (n = 1) and reactive lymph node (n = 1). Five examinations were normal. Soft tissue abnormalities in patients over the age of 14 years were associated with intramuscular injections: fat necrosis (n = 1), haematoma (n = 1), indurated soft tissue (n = 1) and abscess (n = 7). Soft tissue abnormalities with no underlying cause were seen in seven patients: abscess (n = 4), indurated soft tissue (n = 2) and fat necrosis (n = 1). Ultrasound is the imaging modality of choice for delineating these abnormalities and allows percutaneous drainage.
