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.

Article Synopsis
  • A 73-year-old woman presented with swelling in her left cheek, leading to a diagnosis of meningioma with spread along the maxillary nerve.
  • Imaging revealed a mass with both intracranial and extracranial components, affecting several areas including the cavernous sinus and nasal cavity.
  • A biopsy confirmed the condition as meningothelial meningioma, indicating the tumor's complex involvement of surrounding structures.

Article Synopsis
  • The study aimed to determine the exact position of the posterior clinoid process (PCP) in fetuses by measuring its distances to various reference points in the skull base of 32 fetuses (11 males and 21 females) aged 17 to 32 weeks.
  • Measurements showed that the PCP’s distance from various skull features differed slightly by gender and increased significantly with gestational age, indicating growth dynamics of these distances.
  • The research provides linear equations that can be used to estimate how the distances from the PCP change as the fetus develops, which may aid in understanding anatomical variations in fetuses.
