disease agents that principally target the tongue are relatively rare. it seems that type of food and roughage play an important role to predispose the animals to lingual ulcers. during a period of four years different aspects of cattle lingual fossa ulcer were studied in a semi-industrial dairy farm in tehran. the affected animals showed various stages of ulcer formation in their lingual fossa...

abstract a patient with a 3-month history of headache refractory to pain medication was admitted. the ct scan and mri showed evidence of a posterior fossa mass. this was pathologically confirmed as an extra medullary plasmacytoma (emp). he had a pathologic fracture of the left humerus 7 years ago while the radiologist was unaware at the time of diagnosis. a solitary bone plasmacytoma (sbp) was ...

in order to create an effective arteriovenous fistula (avf) in patients with sustained chronic renal failure (crf), surgeons need to become familiar with various anatomical variations of venous structures in the operating field. because of variety and different types of cubital venous anatomies, there is more than a 90% possibility of creating suitable avfs in the cubital fossa , but in the wri...

introduction: atypical infratemporal fossa infections are rare and potentially fatal.   case report: a case of an aspergillosis localized in the infratemporal fossa and another case of tuberculosis of the infratemporal fossa originating from the maxillary sinus, is described. the first patient was immunocompromised and showed symptoms of facial numbness; whereas the other was an immunocompetent...

BACKGROUND AND PURPOSE Posterior fossa syndrome is a severe postoperative complication occurring in up to 29% of children undergoing posterior fossa tumor resection; it is most likely caused by bilateral damage to the proximal efferent cerebellar pathways, whose fibers contribute to the Guillain-Mollaret triangle. When the triangle is disrupted, hypertrophic olivary degeneration develops. We hy...

Studies have reported a functional link between the arc size of the semicircular canals and locomotor agility across adult primates. However, canal size is spatially interlinked with the subarcuate fossa. This fossa can house the petrosal lobule of the paraflocculus, which also plays a role in coordinating head and eye movements. Consequently, it could be that it is the size of the petrosal lob...

In the last years, anthropology has been widely explored mainly when related to bones due to its morphologic characteristics, such as the rhomboid fossa of the clavicle. This study examined the incidence of the rhomboid fossa in paired clavicles of Brazilian subjects obtained from 209 adult bodies of known age and sex (107 males and 102 females) on which postmortem examinations had been perform...
