Name of the Patient : Abc XyzChalmn / F / 20 yrs.
Referred by : Dr. Abc Xyznghvi.
Examination : M.R.I. of the Paranasal Sinus.
CLINICAL PROFILE :
C/O pain in the occipital region since 3-4 days.
C/O right eye proptosis and nasal bleeding since 2-3 months.
M.R.I of the paranasal sinuses was performed using the following parameters :
3 mm thick T2 Weighted (with fat saturation) axial images.
3 mm thick T1 Weighted and STIR coronal images.
The brain was screened with 5 mm thick T2 Weighted axial images.
There is a large, ill-defined mass lesion having its epicentre in the right nasal cavity and in the right maxillary antrum. There is destruction of the inferior wall of the right orbit with involvement of the inferior rectus and oblique muscles. This lesion is seen to expand the right nasal cavity, ethmoidal sinuses and right maxillary antrum. There is extension into the frontal sinus and sphenoid sinus on the right side (? retained secretions/? tumor tissue). There is no obvious extension into the cranial cavity. Hyperintense areas on the T1 Weighted images within the right maxillary sinus and sphenoid and frontal sinus on the right side may represent retained secretions.
There is proptosis on the right side and globe is displaced laterally and anteriorly.
The right optic nerve shows normal signal intensity.

The left orbit is unremarkable.
Both the lateral, third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.
The MRI features are suggestive of a mass lesion having its epicentre in the right nasal cavity and in the right maxillary antrum as described. This may represent a neoplasm like a squamous cell carcinoma or small cell tumors.
