osteoma/癲癇性発作

Osteomas are the most common benign tumours of the sinonasal tract. Even though their location in the sinuses is well known, turbinate osteomas are quite rare. We report one such case of a 26-year-old female who presented with neurological complaints of a seizure rather than nasal complaints. The

BACKGROUND Osteomas of the paranasal sinuses rarely cause intracranial manifestations. A neurological symptom may be the first sign of a previously unrecognized osteoma. METHODS A 28-year-old male was referred with one episode of witnessed tonic-clonic seizure and loss of consciousness. Radiologic

Background Osteomas are rare benign and slow-growing osteogenic tumors mainly involving frontal and ethmoid sinuses. Objectives The primary objective of our study is to present the management of cases of giant frontal sinus osteomas. Secondarily, we describe our modified unilateral osteoplastic flap

Craniofacial osteomas are benign, slow-growing neoplasms of the craniofacial region that are usually asymptomatic. Uncommonly, giant craniofacial osteomas may be symptomatic and cause serious morbidity including ophthalmologic problems, cerebral compression, pneumocephalus, and seizures. We present

Two young adult males presented with paranasal sinus osteoma associated with mucocele. A 20-year-old man presented with headache and seizure, and another 20-year-old man presented with headache, frontal deformity, and visual disturbances. Both patients underwent surgery and satisfactory results were

A 70-year-old man presented with a rare case of paranasal osteoma with secondary mucocele extending intracranially, manifesting as a generalized convulsion. Computed tomography showed a large calcified tumor adjacent to the cystic mass in the left frontal lobe. He underwent left frontal craniotomy,

BACKGROUND Tension pneumocephalus, the accumulation of intracranial gas under pressure, is a rare but potentially life-threatening condition which can complicate craniofacial surgery, trauma, or cranial tumor. It presents as an acute or subacute expanding mass lesion. METHODS We present a case of a

We present a rare case of intracranial mucocele associated with frontal sinus osteoma in a patient suffering from generalized convulsion. The intracranial mucocele occurs as a complication of obstruction of sinus drainage caused by osteoma, but it is often diagnosed preoperatively as an intracranial

BACKGROUND Osteomas of the paranasal sinuses rarely lead to intracranial manifestations. We present an unusual case of a frontal sinus osteoma leading to intracerebral abscess formation. METHODS A 51-year-old Hispanic man presented with increasing frontal headaches, new onset seizure, lethargy,

This case report deals with a 16-year-old girl, admitted for headache and Jacksonian seizures. The clinical examination showed no gross disturbances, but the neuropsychologic examination revealed difficulties in speech-linked abstract thinking. Extensive radiologic investigations revealed the

The percentage of aneurysms measuring more than 2'5 cm in diameter ranges from 3 to 13%, and occur more commonly in females. They come to clinical attention later than nongiant aneurysms, but 20% of them appear in patients 20 years of age or younger. Its natural history is incompletely understood.

The formation of symptomatic intradural mucocele associated with a paranasal osteoma is rare, and no standard treatment has been established. Here, we present a case of intradural mucocele in a 27-year-old man complaining of headache and generalized convulsion. Cranial CT and brain MRI showed a left

During a 3-year period, all inpatients in the psychiatry unit underwent routine screening computed tomography (CT) in an effort to detect clinically unsuspected intracranial abnormalities. Of 261 patients examined who had no focal neurologic deficits, 103 had schizophrenia, 71 had depression, 48 had
