Abstract

Inflammatory pseudotumor most commonly occurs in the orbit and produces orbital pseudotumor, but extension into brain parenchyma is uncommon. We report a case of inflammatory pseudotumor involving sphenoid sinus, cavernous sinus, superior orbital fissure, orbital muscle, and intracranial extension into left temporal lobe producing right hemiparesis and wernicke's aphasia. The patient improved clinically and radiologically with steroid administration. This paper provides an insight into the spectrum of involvement of inflammatory pseudotumor and the importance of early diagnosis of the benign condition.

Coronal T1-weighted contrast image shows proptosis of the right globe. There is intense enhancement and enlargement of the right superior and lateral recti (black arrow).

Figure 3
Coronal and Axial T1-weighted contrast image shows intensely enhancing extra-axial mass lesion extending from left cavernous area compressing and invading left anterior temporal lobe (black arrow). There is significant perilesional edema. Lateral ventricle is compressed with midline shift to the right.
