Name of the Patient : Abc Xyzn Kumar lmn / M / 27 yrs.
Referred by : Dr. Abc Xyzdy.
Examination : M.R.I. of the Left Wrist.
CLINICAL PROFILE :
C/O pain and swelling (progressive) over the left wrist since 3 months.
M.R.I of the left wrist was performed using the following parameters :
3 mm thick T1 Weighted and T2 Weighted (with fat saturation) axial images.
3 mm thick T1 Weighted, STIR and Gradient (with fat saturation)
3 mm thick T1 Weighted sagittal images.
There is a large, lobulated expansile well-marginated mass lesion in the distal end of the ulna on the left side. This lesion measures approximately 2.5 x 2.5 cms and 3.5 cms in its cranio-caudate dimension. There is a well-defined area between the lesion and the normal marrow. This lesion is slightly hyperintense to muscle with few hypointense areas on the T1 Weighted images. This is seen to turn heterogeneously hyperintense on the T2 Weighted, Gradient and the STIR images. Hypointense areas are seen to turn hyperintense on the T2 Weighted images and may represent cystic/necrotic change. There is a break in the cortex anteriorly with slight extension into the anterior soft tissues and anterior displacement of the flexor tendon. The distal radio-ulnar joint is involved. Suspicious involvement of the left wrist joint is also noted. Hyperintense signal is also noted in the subcutaneous region along the medial aspect of the left wrist.
The visualized radius appears normal.
The carpal bones of the left wrist show normal alignment and signal intensity. There is no obvious bone erosion or destruction seen. The intercarpal and radiocarpal joints are unremarkable. No joint effusion is noted.
The MRI features are suggestive of a large, expansile lobulated mass lesion in the distal end of the ulna on the left side measuring approximately 2.5 x 2.5 cms and 3.5 cms in its cranio-caudate dimension with extensions as described. This most probably represents a giant cell tumor.
