Background: Pattern of origin of anterior inferior artery is important in interpretation of posterior circulatory stroke and during posterior cranial fossa surgery for aneurysms, arteriovenous malformations, tumors, posterior cerebral revascularization, and in diagnostic as well as interventional neuroradiology. The pattern displays ethnic variation but data from African populations are scanty....

It has been alleged that radioisotope scanning of posterior fossa lesions is of little value (1-8) or at best, difficult (9,10) and frequently unrewarding (11). Some clinics even report the virtual abandonment of posterior fossa scanning (12,13). On the other hand, there are those who maintain that scanning of the posterior fossa is a worthwhile adjunct in the evaluation of lesions in that re g...

Purpose: Using the methods of radiation diagnostics, to trace in dynamics structural and topographic state temporomandibular joint (TMJ) before after orthognathic treatment patients with air conditioning Material Methods: A CT analysis TMJ condition was carried out orthodontic surgical removal dentofacial anomaly (skeletal form) effects Candyline resorption. We used method Fadeev R.A. et al. as...

Germ cell tumors comprise approximately 2-5% of all childhood brain tumors. They arise predominantly in the pineal and suprasellar region, but may occur throughout the brain. Teratomas are generally divided into gonadal and extragonadal types. A posterior fossa teratoma is a rare occurrence. The focus of this discussion is a 5-year-old boy with posterior fossa teratoma who recovered completely ...

Introduction: Eagle’s syndrome is a constellation of signs secondary to an elongated styloid process or due to mineralization of the stylohyoid or stylomandibular ligament or the posterior belly of the digastric muscle. The syndrome includes symptoms ranging from stylalgia (i.e. pain in the tonsillar fossa, pharyngeal or hyoid region) to foreign-body sensation in the throat, cervicofacial pain,...

Posterior fossa syndrome is characterized by cerebellar dysfunction, oromotor/oculomotor apraxia, emotional lability and mutism in patients after infratentorial injury. The underlying neuroanatomical substrates of posterior fossa syndrome are unknown, but dentatothalamocortical tracts have been implicated. We used pre- and postoperative neuroimaging to investigate proximal dentatothalamocortica...

Until recently, angiography has been of little help in the diagnosis of mass lesions of the posterior fossa. Advances in neuroradiology have now made posterior fossa angiography the procedure of choice in many cases. The anatomy and radiography of the veins of the posterior fossa have been detailed by Huang and Wolf (1965, 1966). Reports of angiographic (especially venographic) features of post...

One case of traumatic posterior fossa subdural hematoma (PFSH) is described. This location represent 1% of the subdural hematomas. Computerized Tomography (CT) was used in the diagnosis and follow-up of the hematoma. The etiology and physiopathology of this process are discussed.
