Rhino-orbital-cerebral mucormycosis is an invasive disease caused by fungi. Diabetes mellitus and solid organ transplantation are known risk factors, while it increasingly recognized in patients with COVID-19 although the exact causal relationship unknown. Early diagnosis treatment liposomal amphotericin B surgical debridement carries a better outcome these patients. We present case of extensiv...

Seventy dry skulls were obtained from the Department of Anatomy. Of these, 2 skulls showed occipitalization. These were photographed and radiographed. Several measurements, including cranial index, dimensions of the foramen magnum, basal angle and basal impression, were taken. Both skulls showed near by complete fusion of the atlas with the occipital bone. A continuation of the confluence of th...

Three infants with congestive cardiac failure demonstrated dilated and hyperdense intracranial veins and sinuses on noncontrast cranial CT. Intracranial venous thrombosis and arteriovenous malformation were excluded in two infants by autopsy and in one infant by MR imaging. We believe the CT findings were secondary to an elevated central venous pressure caused by the cardiac failure. This CT pa...

1. A microscopic and bacteriological analysis of the meningitis produced in the chick embryo following inoculation of meningococci into the body wall or into the amniotic cavity indicates that the meninges are invaded by way of the blood stream. 2. There is no indication that a direct extension of the infection by way of the middle ear, the cranial sinuses or the pia-arachnoid sheath of the olf...

The subcranial approach has emerged as a safe and effective procedure for resection of tumors of the anterior skull base. This approach allows excellent exposure of the nasal cavities, the paranasal sinuses, and the orbit 1 I also enables a wide approach to the anterior cranial fossa, while applying minimal retraction of the frontal lobes. Complications of this procedure are acceptable and comp...

directly related with intracerebral hemorrhage in dural arteriovenous fistula (DAVF) because the cortical vein anatomically exists in the subarachnoid space [1]. Hemorrhage is the most serious event in cranial DAVF. Cortical venous reflux (CVR) has been known as a prognostic risk factor for hemorrhage in cranial DAVF [2]. Hemorrhage risk is related to lesion location, sex and cortical venous re...

We describe the clinical, MR imaging, and pathologic findings in two cases of primary sellar lymphoma in immunocompetent individuals. Both patients had hypopituitarism, and one patient had a sixth cranial nerve palsy. MR images depicted sellar and suprasellar masses in both patients, and extension into the cavernous and sphenoid sinuses was also present in one patient. The pathologic diagnosis ...

Three patients with diffuse idiopathic cranial pachymeningitis with predominant involvement of the tentorium and falx are reported. Progressively increasing headaches were the usual symptoms, along with ataxia and various cranial nerve palsies. CT in all cases and MR imaging in two cases detected isolated thickened dura mater. In one case, MR depicted dural involvement as a very large, hypointe...
