However, different embryonic types persist, in which the SMCV drains into the lateral sinus. The basal type of SMCV coursing on the middle fossa floor is a scarce variant. Materials and Methods: During a retrospective study of archived computed tomography angiography (CTA) and magnetic resonance angiography (MRA) files, three rare adult cases of the basal or sphenopetrosal type of SMCV were found and further documented. Results: In the first case, which was evaluated via CTA, the basal type of SMCV formed a sagittal loop. It continued on the middle fossa floor, over a dehiscent tegmen tympani, to drain into the lateral sinus. In the second case, documented via MRA, the basal type of SMCV\u2019s anterior loop was in the coronal plane and closely related to the internal carotid artery and the cavernous sinus. It continued with the basal segment over a dehiscent glenoid fossa of the temporomandibular joint (TMJ). In the third case, documented via CTA, the initial cerebral part of the SMCV had a large fenestration. The middle fossa floor coursed within a well-configured sulcus of the SMCV and received a tributary through the tympanic roof. Its terminal had a tentorial course. Conclusions: Beyond the fact that such rare variants of the SMCV can unexpectedly interfere with specific approaches via the middle fossa, dehiscences of the middle fossa floor beneath such variants can determine otic or TMJ symptoms. Possible loops and fenestrations of the SMCV should be considered and documented preoperatively.<\/jats:p>","DOI":"10.3390\/medicina60020209","type":"journal-article","created":{"date-parts":[[2024,1,25]],"date-time":"2024-01-25T10:03:48Z","timestamp":1706177028000},"page":"209","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["The Basal or Sphenopetrosal Superficial Middle Cerebral Vein Type"],"prefix":"10.3390","volume":"60","author":[{"given":"Adelina Maria","family":"Jianu","sequence":"first","affiliation":[{"name":"Department of Anatomy and Embryology, Faculty of Medicine, \u201dVictor Babes\u201d University of Medicine and Pharmacy, 300041 Timisoara, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7599-6023","authenticated-orcid":false,"given":"Monica Adriana","family":"Vaida","sequence":"additional","affiliation":[{"name":"Department of Anatomy and Embryology, Faculty of Medicine, \u201dVictor Babes\u201d University of Medicine and Pharmacy, 300041 Timisoara, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8723-0540","authenticated-orcid":false,"given":"Mugurel Constantin","family":"Rusu","sequence":"additional","affiliation":[{"name":"Division of Anatomy, Faculty of Dentistry, \u201cCarol Davila\u201d University of Medicine and Pharmacy, 050474 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandra Diana","family":"Vrapciu","sequence":"additional","affiliation":[{"name":"Division of Anatomy, Faculty of Dentistry, \u201cCarol Davila\u201d University of Medicine and Pharmacy, 050474 Bucharest, Romania"},{"name":"University Emergency Hospital Bucharest, 050098 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,25]]},"reference":[{"key":"ref_1","unstructured":"Jinkins, J.R.
