Name of the Patient : Abc Xyz D. Suttarlmn / M / 55 yrs.
Referred by : Dr. Abc Xyzpadia.
Examination : M.R.I. of the Upper Right Tibia.
CLINICAL PROFILE :
C/O swelling with pain over the upper right tibia.
HP s/o a low grade malignant fibrous histiocytoma.
M.R.I. of the upper right tibia was performed using the following parameters :
4 mm thick T1 Weighted and GRASS sagittal images.
5 mm thick T1 Weighted and STIR coronal images.
5 mm thick T1 Weighted and T2 Weighted (with fat saturation) axial images.
There is evidence of a well-defined, expansile mass lesion involving the upper end of the right tibia, more to the right. This lesion is seen to extend from the upper surface of the tibia and its inferior extent is approximately 8.0 cms from the right knee joint. The mass lesion is seen to measure approximately 4.0 x 5.0 x 8.0 cms.
This lesion is hypointense on the T1 Weighted images and turns hyperintense on the T2 Weighted, STIR and GRASS images (few hypointensities are seen within the lesion and may represent fibrous tissue/paramagnetic substances). There is erosion of the anterior and lateral aspect of the cortex of the right upper tibia with slight extension of the lesion into the adjacent soft tissues.
The margins of this lesion are well-demarcated from the normal bone. There is no obvious invasion of the right knee joint per se by this lesion.
Incidental note is made of varicose veins.
In a known C/O malignant fibrous histiocytoma, the MRI features are suggestive of a well-defined, mass lesion involving the right upper tibia measuring approximately 4.0 x 5.0 x 8.0 cms. The lesion does not appear to involve the right knee joint per se.
