Fibrolipomatous hamartoma in a 45-year-old male presenting with a lump of 1-year duration in the first web space of the left hand. (a) T1w sequence shows a well-circumscribed hyperintense lobulated subcutaneous lesion within the first web space, with curvilinear low-signal structures (arrow), similar to a “spaghetti-like” appearance. (b) On T2w-FS sequence the lesion shows homogeneous signal loss indicating a predominantly fatty lesion while the curvilinear structures coursing through the centre of the lesion appear hyperintense. (c) These curvilinear structures show enhancement (arrow). These were found to represent neurovascular components of the lesion intraoperatively. The rest of the lesion does not show significant enhancement
