47 year old female with pain and right third digit proximal nailbed suspected glomus tumor. The patient returned for additional imaging of the DIP joint of the middle finger using a microscopy coil. The patient while not be charged for these images.A marker was placed along the ulnar aspect of the PIP joint. Best seen on the axial proton density fat saturated images is a small focus of increased signal intensity along the dorsal and ulnar aspect of the PIP joint that measures 2 mm in the transverse dimension and approximately 4 mm in the longitudinal dimension corresponding to the focus of enhancement seen on the prior study. The small focus of signal abnormality lies immediately volar to the ulnar collateral ligament. The ligament itself, however, can be traced on these images from the head of the middle phalanx to the base of the distal phalanx and appears to be intact. The remaining visualized bone and soft tissue structures are unremarkable.
Small nodular focus of abnormal signal intensity corresponding to enhancement seen on the initial study. While it is conceivable that this could represent a glomus tumor, it remains nonspecific and could represent a synovitis arising from the joint.
