RARE TUMORS OF POSTERIOR CRANIAL FOSSA IN ADULTS: A SINGLE UNIT EXPERIENCE AND LITERATURE REVIEW

Objectives Tumors arising in the posterior cranial fossa pertain to a special category of neoplasm in the manner that they can cause cerebellar syndrome, obstructive hydrocephalus, brainstem compression – cranial nerve dysfunction – and herniation.

Development of the nasal capsule in Emydura subglobosa (Testudines: Pleurodira) with a comparison to other turtles

The Anatomical Record, EarlyView.
Abstract Extant turtles occupy freshwater, marine, and terrestrial habitats, and their nasal region provides important evidence for the evolution of respiration‐ and sensory‐related cranial morphology. However, developmental data on the turtle nasal capsule remain limited, particularly in Pleurodira.

Morphological analysis of posterior fossa in Apert and Crouzon syndromes before and after posterior cranial vault expansion

International audienceBackground: Syndromic craniosynostosis, such as Apert and Crouzon syndromes, involve premature fusion of cranial sutures, leading to cranial deformities and potential neurological complications.

Anatomy and variation in the paraphyletic Mosasaurus lemonnieri assemblage from the Craie phosphatée de ciply, Belgium

The Anatomical Record, EarlyView.
Abstract Nineteenth century excavations of the Ciply‐Malogne Phosphatic Chalk Formation in Hainaut, Belgium, yielded over 50 partial mosasaur skeletons, the majority of which were referred to the species Mosasaurus lemonnieri Dollo, 1889. In the years since, this taxon has experienced a complicated taxonomic history, and its exceptional hypodigm has ...

Obsessive-Compulsive Disorder Associated with Posterior Cranial Fossa Meningioma

Case Reports in Psychiatry, 2017
We report here a patient in whom the effects of a cerebellum mass may have led to development of obsessive-compulsive disorder (OCD). A 33-year-old woman showed symptoms of OCD, including obsessive worry about infection from tainted blood and repetitive ...

Assessment of intraspecific skull variation in the Campanian baenid turtle Plesiobaena antiqua

The Anatomical Record, EarlyView.
Abstract Baenids are freshwater paracryptodiran turtles with a fossil record ranging from the Early Cretaceous to the Eocene. The baenid Plesiobaena antiqua is the most common turtle in the Campanian (Late Cretaceous) Dinosaur Park Formation in Canada, but the apparent intraspecific variation remains poorly understood.

Posterior fossa morphology and cranial nerve configuration in trigeminal neuralgia: A morphometric magnetic resonance imaging study

Background: Neurovascular compression is considered the principal cause of trigeminal neuralgia (TN), but vascular contact alone does not fully explain disease occurrence.

Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

The Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.
