Utility of High Resolution Ultrasound in Diagnosis of Aneurysmal Bone Cyst in Clavicle
Journal Title: Scholars Journal of Medical Case Reports - Year 2018, Vol 6, Issue 5
Abstract
The clavicle is an unusual site for primary bone tumors among flat bones. True benign neoplasm of clavicle is less common than malignant. Aneurysmal bone cyst (ABC) is an uncommon benign tumor in clavicle which is commonly seen in long bones. The clavicle is involved in 3% of all cases of ABC. ABC can be primary, arising de novo and secondary (arise adjacent to or in conjunction) with primary bone tumor. Ultrasound (USG) is extremely useful in detecting primary and secondary bone tumors causing cortical disruption with the soft tissue component. The USG can detect fluid –fluid levels within ABC, which move with changes in the patient’s position. If 100% of the lesion showed fluid- fluid levels, malignant aetiology is unlikely. We report a case of a 11- year old female patient presented to the ultrasound department for painless swelling in right clavicular and supraclavicular region since 1 month. Lateral half of clavicle showed an expansile well-defined multilocular and cystic lesion showing multiple medium level internal echoes which moved with gravity with fluid-fluid levels. No solid component was noted. Findings were suggestive of aneurysmal bone cyst arising from right clavicle showing hemorrhage in various stages. Fine needle aspiration cytology was suggestive of aneurysmal bone cyst.
