Name of the Patient : Abc Xyzlmn / M / 27 yrs.
Referred by : Dr. Abc Xyzengsarkar.
Examination : M.R.I. of the Right Ankle & Foot.

CLINICAL PROFILE :

H/O fall from a vehicle with pain in the right ankle since 1 1/2 years.

EXAMINATION :

M.R.I. of the right ankle and foot was performed using the following parameters :

3 and 4 mm thick T1 Weighted and 3 mm thick STIR coronal images.

3 mm thick T1 Weighted and STIR axial images.

4 mm thick T1 Weighted and GRASS sagittal images.

OBSERVATION :

There is a small hypointense area in the subchondral region at the superior and medial aspect of the right talor dome on the T1 Weighted images which measures approximately 1.0 x 0.5 cms. This lesion is seen to turn hyperintense on the GRASS and STIR images. There is surrounding edema in the adjacent marrow of the talus. Slight thinning of the articular cartilage in the medial aspect of the tibio-talor joint is seen. Minimal fluid is noted in the tendon sheath of the flexor hallucis longus.

No obvious bone destruction or erosion is evident.

The fibres of the tibio-talor ligament (deltoid ligament) are not well-identified (? partial/complete tear). Fibres of the tibio-calcaneal ligament are however intact.

IMPRESSION :

In the given clinical setting of trauma, the MRI features are suggestive of an osteochondral lesion of the talus, corresponding to stage IIB, i.e. incomplete separation of the fragment. Fibres of the tibio-talor ligament are not well-identified. Fluid is noted in the tendon sheath of the flexor hallcuis longus.
