Name of the Patient : Abc XyzJolmn / M / 54 yrs.
Referred by : Dr. Abc Xyzah.
Examination : Intracranial M.R.A.

CLINICAL PROFILE :

C/O drooping of the right eyelid with diplopia and left sided headaches since 1 month.

EXAMINATION :

The brain was scanned with 5 mm thick T2 Weighted axial images, 4 mm thick T1 Weighted and STIR coronal images and 5 mm thick T1 Weighted sagittal images.

Intracranial MRA was performed with a 3D TOF sequence.

OBSERVATION :

There is seen a well-defined, expansile lesion in the sphenoid sinus measuring approximately 5.3 x 3.6 x 2.9 cms. This lesion is slightly hyperintense to CSF on all the pulse sequences. Extension of the lesion into the posterior ethmoidal air cells on the left is noted. There is elevation of the floor of the sella, which appears flattened. The pituitary gland is displaced superiorly with compression upon the optic chiasm more so on the right side. Slight compression upon the cavernous sinuses is noted.

There is no focal area of altered signal intensity within the brain parenchyma.

Both the lateral, third and the fourth ventricles are normal.

The optic nerves show normal signal intensity.
Scan-00001



INTRACRANIAL MRA :

The petrous, cavernous and supraclinoid segments of the internal carotid arteries bilaterally show normal signal and calibre. The visualized anterior cerebral, middle cerebral, basilar, vertebral and posterior cerebral arteries also show normal signal, calibre and wall margins. No obvious aneurysm or vascular malformation is identified.

IMPRESSION :

An expansile mass lesion in the sphenoid sinus as described, most likely represents a mucocele of the sphenoid sinus.

No significant abnormality is detected in the brain parenchyma per se or on the intracranial MRA on this study.
