Intracranial metastasis of prostate cancer is rarely seen, and there are few studies in this regard in the literature. Most of these studies in the literature comprise the metastasis of prostate cancer to the sphenoid sinus, and metastasis to the frontal and ethmoid sinus is a much rare entity. Association of visual symptoms, epistaxis, headache, and hematuria may indicate a urologic malignancy in terms of the origin of the primary tumor. This study was aimed to present the prostate cancer case of a 73-year-old patient whose paranasal sinus tomograms revealed the presence of frontal and ethmoid sinus metastasis...

Seizure is a classical feature of intra axial brain parenchymal lesion. Simple bone cyst is an unusual bony pathology at skull base presenting with unexpected symptoms of complex partial seizures. Skull base neuro-endoscopy has managed such lesions more effectively with reduced post-operative morbidity as compared to transcranial approach. This case report discusses a 20-year-old male who presented with 3 episodes of seizure over a time period of 10 months. MRI brain revealed T1 hypo and T2 hyper intense cystic lesion in middle cranial fossa with no enhancement on contrast administration...

A 58-year-old woman who had presented for upper gastrointestinal barium examination accidently slipped from the movable bed, and her head became compressed between the end of the bed and the side wall. She suffered massive bleeding from her nose and ear followed by cardiac arrest, and subsequent attempts at cardiopulmonary resuscitation failed. A medicolegal autopsy was performed to reveal the cause of death, as part of the investigation of the accident. During the autopsy, postmortem cerebral CT angiography was carried out by injection of 5% gelatin-barium emulsion as a radiopaque contrast medium into the bilateral common carotid arteries, demonstrating transudation of the contrast medium into the right acoustic meatus and the sphenoidal sinus cavity...

BACKGROUND: Traumatic clival fractures occur with < 0.6% frequency and can be associated with significant neurovascular injuries. The most serious of these injuries is to the basilar artery in which the artery is dissected or is fully occluded resulting in infarction of the brainstem and cerebellum. Among early reports of these injuries, postmortem autopsy showed entrapment, or incarceration, of the basilar artery at the clival fracture site. A literature search revealed 11 cases of entrapment of the basilar artery within a clival fracture...

Chronic sphenoid rhinosinusitis is a spectrum of inflammatory diseases in isolated sphenoid sinus which may persist over a period of 12 weeks. It is a different entity from other types of rhinosinusitis because clinical presentations include headache, visual loss or diplopia, and patients may or may not have nasal obstruction or nasal discharge. Nasal endoscopic examination is useful, and computed tomography is mandatory. The disease requires comprehensive knowledge and appropriate imaging technique for diagnosis...

Hongyan Liu, Guoqi Wang, Weijun Gu, Yiming Mu
Pituitary adenomas with sphenoid sinus or clivus invasion are not uncommon, but the pathogenesis responsible for this phenomenon remains unclear. Cathepsin K, expressed predominantly in osteoclasts, can degrade type I collagen and plays an essential role in bone resorption. Recent studies reported the expression of Cathepsin K in various malignant tumors, such as bone, breast, lung and prostate cancers, and its expression is further increased in bone metastasis or invasive subpopulations. In addition, cathepsin K inhibitors (CatKi) were demonstrated to effectively prevent or reduce osteolytic lesions in breast cancers with bone metastasis...

BACKGROUND: Surgery improves symptoms for the majority of chronic rhinosinusitis (CRS) patients; however, physiological changes in the sinus cavities remain poorly characterized. Direct measurement of changes in airflow, pressure, temperature, humidity, and intranasal spray distribution following surgery is technically challenging. Accordingly, we have used computational fluid dynamic modeling to quantify how these parameters change postoperatively. METHODS: Computed tomography images from a normal control, a patient with CRS preoperatively and postoperatively, and a patient following an endoscopic Lothrop procedure (ELP) were used to create 4 three-dimensional models of the sinus cavities...

OBJECTIVE Exposure of the cavernous sinus is technically challenging. The most common surgical approaches use well-known variations of the standard frontotemporal craniotomy. In this paper the authors describe a novel ventral route that enters the lateral wall of the cavernous sinus through an interdural corridor that includes the removal of the greater sphenoid wing via a purely endoscopic transorbital pathway. METHODS Five human cadaveric heads (10 sides) were dissected at the Laboratory of Surgical NeuroAnatomy of the University of Barcelona...

We report a case of retiform hemangioendothelioma (RH) located in the infratemporal fossa and buccal area in a 13-year-old Korean boy. The tumor originated from the sphenoid bone of the infratemporal fossa area and spread into the cavernous sinus, orbital apex, and retro-nasal area with bone destruction of the pterygoid process. Tumor resection was conducted via Le Fort I osteotomy and partial maxillectomy to approach the infratemporal fossa and retro-nasal area. The diagnosis of RH was confirmed after surgery...

BACKGROUND: Spontaneous cerebrospinal fluid leaks are rare but may lead to confusion with other diseases in patients without history of trauma. We report a rare case unusual for two reasons. First, our patient was put under antiallergic medication for months before the diagnosis of spontaneous cerebrospinal fluid leak of the sphenoid sinus. Second, our patient was managed successfully by a ventriculoperitoneal shunt. CASE PRESENTATION: Our patient was a nonobese 49-year-old Arab man without history of trauma or surgery who presented with rhinorrhea...
