Well delineated lucent multiloculated lesion involving the hamate.
From the case:
Intraosseous lipoma of the hamate
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/107704/annotated_viewer_json?lang=us"}
A well-delineated high signal (on T1/T2 sequences) intraosseous lesion in the hamate with thin internal septations, which shows signal drop on PD fat suppression sequences
A focal central high signal (on T2/PD fs) area at hamate hook suggests the presence of fluid raising suspicion of cystic degeneration component.
Case Discussion
Intraosseous lipomas have a characteristic appearance in imaging studies. They belong to the classical "don't touch" lesions of the bone.
