Name of the Patient : Abc Xyzchandra G. lmn / M / 58 yrs.
Referred by : Dr. Abc Xyzh.
Examination : M.R.I. and M.R.A. of Abdominal Aorta.

CLINICAL PROFILE :

Known C/O CRF. Diagnosed 15 days back.
C/O breathlessness, giddiness, fatigability with increased hypertension 8 months back. Recovered.
Now similar complaints since 15 days.
Suspected dissecting aneurysm of aorta (D12-L1) on angiogram.

EXAMINATION :

MR angio of the abdominal aorta was performed using 2D TOF sequences.

7 mm thick T1 Weighted and T2 Weighted axial images.

5 mm thick T1 Weighted sagittal and coronal images.

OBSERVATION :

There is seen fusiform dilatation of the abdominal aorta extending over approximately D7 to D12 vertebral levels. The maximum dimensions of the aorta in the axial plane over these levels is about 5.2 cms (width) and 4.1 cms (AP dimension). The aortic wall over these levels appears thickened. There is an intermediate signal intensity lesion on the T1 Weighted images along the anterior and right lateral wall of the dilated segment of the aorta. This lesion appears hyperintense on the T2 Weighted images. The origin of the coeliac artery is not well identified on this study. The origin of the superior mesentric artery is however, well identified and is just distal to the dilated segment of the aorta. The origins of the renal arteries are well identified on the T1 Weighted coronal images and are also distal to the dilated aortic segment (107.8).


BR>
The right kidney appears smaller in size.

The thoracic aorta and the aortic arch were screened with 7 mm thick T1 Weighted axial images.

An aberrant right subclavian artery is noted traversing posterior to the trachea.

The aorta in the lower thoracic region also appears slightly increased in diameter over about 2 vertebral segments (111.20 - 23).

IMPRESSION :

1. Fusiform aneurysm of the abdominal aorta extending over about the D7 to D12 vertebral levels with a probable thrombus along its anterior and right lateral wall (there is no definite evidence of aortic dissection on this study).

2. Slight increase in diameter of the lower thoracic aorta.

3. Aberrant right subclavian artery.

4. Small right kidney.
