Variations at the skull base can result in misinterpretation of radiological imaging and occasionally, iatrogenic injury. Here, we describe, to our knowledge, the second reported case of a duplicated foramen rotundum. The morphometrics of this finding are documented and the anatomy and potential clinical consequences of such an anatomical variation discussed. Such a finding is of archival value. Additionally, foramen rotundum duplication such as found in our case might also lead to complications while using, for example, transsphenoid approaches to the middle cranial fossa as well as various transfacial treatments for trigeminal neuralgia which rely on observing the foramina around the foramen ovale on fluoroscopy for correct positioning of needles and catheters.

Schwannomas are benign tumors that can develop in any part of a nerve containing Schwann cells. Skull base schwannomas are rare, representing approximately 4% of extracranial schwannomas. Among these, vidian nerve schwannomas are particularly uncommon, with only a few documented cases.

There are reported here multiple rare anatomical variants of the sphenoidal sinus found in a 53-year-old male. The sinus exhibited uncommon features, including a prominent occipital recess extending bilaterally into the basilar part of the occipital bone. A narrow posterior isthmus connected the main chamber to 2 recesses: a superior postsellar recess pneumatising the dorsum sellae, and a postero-inferior occipital recess.
