The classical term "pituitary apoplexy" (PA) describes a clinical syndrome usually characterized by abrupt onset of headache accompanied by neurologic and/or endocrinologic deterioration due to sudden expansion of a mass within the sella turcica as a result of hemorrhage or infarction within a pituitary tumor and adjacent pituitary gland. PA is a medical emergency and a difficult diagnosis to establish. Thus this article reviews the presenting symptoms of PA patients to help clinicians recognize or at least suspect this critical condition early on...

BACKGROUND: Cerebral venosinus thrombosis (CVT); is an uncommon, potentially fatal disease that is more common in young adults and children. Thrombophilia, elevated estrogenic states, and infections are the most common risk factors in patients who develop CVT. CASE: A 69-year-old man with a right-sided odontogenic infection presented with fever, headache, opthalmoplegia, and periorbital swelling. Imaging revealed evidence of meningitis and thrombosis of bilateral ophthalmic veins, the cavernous sinus, right internal jugular vein, and sigmoid sinus...

Extranodal natural killer (NK)/T-cell lymphomas are rare, highly aggressive tumors of the central nervous system (CNS) that commonly affect the nasal cavity or paranasal sinuses. NK/T-cell lymphomas are associated with a poor prognosis, as they exhibit a wide range of unique clinical presentations and neuroimaging findings that are currently difficult to detect. Pathological examination is considered to be more reliable for defining the pathological entity of NK/T-cell lymphoma. Early testing for fluorodeoxyglucose (FDG)-positron emission tomography combined with computed tomography may improve the evaluation of lymphomas, which have been known to display avid (18)FDG uptake...

Artiodactyl cranial arterial patterns deviate significantly from the standard mammalian pattern, most notably in the possession of a structure called the carotid rete (CR)-a subdural arterial meshwork that is housed within the cavernous venous sinus, replacing the internal carotid artery (ICA). This relationship between the CR and the cavernous sinus facilitates a suite of unique physiologies, including selective brain cooling. The CR has been studied in a number of artiodactyls; however, to my knowledge, only a single study to date documents a subset of the cranial arteries of New World camelids (llamas, alpacas, vicugñas and guanacoes)...

BACKGROUND Primary pituitary tuberculosis (in absence of other organ involvement and constitutional symptoms) is an extremely rare disease with total reported cases in the literature fewer than a hundred. Misdiagnosis as pituitary adenoma is common and late diagnosis can result in a permanent endocrine dysfunction and/or long-term neurologic sequelae. CASE REPORT We report on the case of a middle-aged woman who presented with severe headache and left third cranial nerve palsy. Magnetic resonance imaging (MRI) revealed a large pituitary tumor invading the left cavernous sinus...

OBJECTIVE: Although hemangiomas are common lesions of the head and neck, sinonasal hemangiomas are rare. The purpose of this study was to analyze the clinical features (sex, age, symptoms, and size and anatomical location of the lesion) and the histological findings of sinonasal hemangioma cases, to assess preoperative transarterial embolization, and to evaluate the outcome (recurrence or no recurrence) of endoscopic sinus surgery. METHODS: Clinical records of 31 patients who underwent endoscopic sinus surgery for resection of sinonasal hemangioma between January 2010 and June 2015 were retrospectively reviewed...

Background Carotid cavernous fistulas (CCFs) Barrow type 'B' are dural shunts between the meningeal branches of the internal carotid artery and the cavernous sinus. The symptoms include vision deterioration, ophthalmoplegia with diplopia, exophthalmos, conjunctival injection, chemosis, ocular bruit, seizures, or neurological deficit. Endovascular treatment remains the gold standard for treatment through the transvenous or transarterial routes. The transvenous approaches have been proved to be the first option...

Bilateral carotid cavernous fistulas are rare entities that can cause debilitating symptoms and can lead to more severe consequences if left untreated. Therefore, the recognition and adequate treatment of these pathologies is very important. We present 2 cases of bilateral carotid cavernous fistulas that arose as a result of cavernous sinus thrombosis. We review the literature and discuss the pathophysiology, symptomatology, management, and treatment of bilateral carotid cavernous fistulas. Within our own cases, treatment of the patients was varied...

OBJECTIVE Parasellar meningiomas tend to invade the suprasellar, cavernous sinus, and petroclival regions, encroaching on adjacent neurovascular structures. As such, they prove difficult to safely and completely resect. Stereotactic radiosurgery (SRS) has played a central role in the treatment of parasellar meningiomas. Evaluation of tumor control rates at this location using simplified single-dimension measurements may prove misleading. The authors report the influence of SRS treatment parameters and the timing and volumetric changes of benign WHO Grade I parasellar meningiomas after SRS on long-term outcome...

REVIEW
Orrett E Ogle
The pathogenesis of odontogenic infection is polymicrobial, consisting of various facultative and strict anaerobes. The dominant isolates are strictly anaerobic gram-negative rods and gram-positive cocci. The periapical infection is the most common form of odontogenic infection. Although odontogenic infections are usually confined to the alveolar ridge vicinity, they can spread into deep fascial spaces. Cavernous sinus thrombosis, brain abscess, airway obstruction, and mediastinitis are possible complications of dental infections...
