Subungal Glomus Tumour-MRI

Small oval altered signal intensity soft tissue lesion on volar aspect of tip of left index finger displaying isointense signals to muscle on T1 weighted imaging and hyperintense on T2 weighted and STIR sequences. No evidence of MR demonstrable calcification present. No connection with the DIP joint or synovial cavity noted. Scalloping of distal phalanx seen on volar aspect with no e/o any destructive lesion. On MRI glomus mass is usually isointense to dermis of the nail bed on T1 weighted images and homogenously hyperintense on T2 and Fat sat T2 weighted images. Axial and coronal T2 weighted images are usually enough to make the diagnosis. Case submitted by Dr Rishu Sangal, MD.
