Name of the Patient : Abc Xyzheb Shlmn / M / 68 yrs.
Referred by : Dr. Abc XyzBR> Examination : M.R.I. of the Left Foot.

CLINICAL PROFILE :

Known diabetic. On Rx.
H/O shoe bite 8 days back with disarticulation at the 1st metatarsophalyngeal joint 4 days back.
Now C/O swelling over the left foot since then.

EXAMINATION :

M.R.I of the left foot was performed using the following parameters :

4 mm thick T1 Weighted and T2 Weighted axial (with fat saturation) images.

4 mm thick T1 Weighted and GRASS sagittal images.

5 mm thick T1 Weighted and STIR coronal images.

OBSERVATION :

There is evidence of disarticulation at the first metatarsophalyngeal joint with a surgical defect in that region. There is an intermediate intensity soft tissue lesion on the T1 Weighted images on the dorsum and the plantar aspect of the left foot at the site of previous surgery, around the head of the left metatarsal. This lesion appears hyperintense on the T2 Weighted and STIR images and may represent post-operative changes in the given clinical setting. Similar ill-defined, hyperintense, signal on the T2 Weighted and STIR images is noted in the subcutaneous tissues of the dorsum of the foot and in the intermuscular planes in the plantar aspect of the foot. Minimal fluid is noted around the tibio-talar joint.


The rest of the joints of the left foot and ankle show normal alignment. The visualized ligaments and tendon sheaths are unremarkable.

There is a well-marginated, approximately 1.0 cm diameter sized hypointense lesion on the T1 Weighted images in the region of the neck of the talus. This lesion appears hyperintense on the T2 Weighted images.

The rest of the bones of the left foot and ankle show normal signal characteristics. There is no bone destruction or erosion noted.

IMPRESSION :

1. Post-operative status.

2. Changes in the soft tissues around the head of the first metatarsal may be due to previous surgery.

3. Altered signal in the subcutaneous tissues and in the intermuscular planes around the left foot may suggests cellulitis in the given clinical setting.

4. Altered signal intensity lesion in the neck of the talus is not specific for a single etiology. This lesion may represent a degenerative cyst/marrow inhomogeneity.
