A 74-year-old woman presented with malignant progression of remnant epidermoid cyst manifesting as sudden onset of right ptosis and double vision. She had right oculomotor nerve paresis. She had a history of surgery for right cerebellopontine angle epidermoid cyst 20 years previously. T(1)-weighted magnetic resonance (MR) imaging demonstrated a hypointense(More)
About 20 cases of cerebrovascular accidents in amusement parks have been documented. However, only a few cases of amusement park stroke (APS) after roller coaster rides have been reported. Here, we present triggers of stroke, clinical characteristics, and the angiographic appearance of 3 consecutive patients of APS. Their clinical characteristics included(More)
After coil embolization, recanalization in cerebral aneurysms adversely influences long-term prognosis. Proliferation of endothelial cells on the coil surface may reduce the incidence of recanalization and further improve outcomes after coil embolization. We aimed to map the expression of proliferating tissue over the aneurysmal orifice and define the(More)
Intracranial aneurysms are extremely rare in infants, and to our knowledge only seven infants treated for ruptured spontaneous dissecting aneurysms have been reported. Good outcomes have been achieved with endovascular treatment of infantile aneurysm. We the endovascular treatment of a one-month-old girl for ruptured dissecting aneurysm located in the(More)
We report a 39-year-old man referred to our facility with linear sclerotic lesions along the several Blaschko's lines of the scalp. A year before the referral, he had had an episode of brain hemorrhage, although there was no evidence of vascular malformation or any other risk factors of brain hemorrhage for his young age. On the diagnosis of scleroderma en(More)
Horner syndrome due to injury to the cervical sympathetic trunk (CST) is a very rare complication of anterior cervical decompression and fusion (ACDF). We have not mentioned the possibility of Horner syndrome as a postoperative complication in patients before surgery. We present a patient with Horner syndrome after ACDF and discuss the anatomical background(More)
BACKGROUND Infectious intracranial aneurysms (IIAs) are rare but can cause substantial morbidity and mortality. We aimed to re-evaluate the role of endovascular therapy for the treatment of IIAs. METHODS This study is a retrospective review of patients diagnosed with IIAs and treated by endovascular therapy in our institutions over the past 13 years. (More)
Objective Osteochondroma (OC) is the most common benign bone neoplasm. It infrequently occurs in the cranial cavity as a calcified lesion and very rarely presents in the sellar region. The present study summarizes the knowledge about OCs of the sellar region. Methods We searched the literature search for the clinical appearance of OCs and other calcified(More)
We report two cases of proximal posterior cerebral artery (PCA) aneurysms treated with endovascular parent artery occlusion (PAO) with coils. In both cases, selective injection from the 4 F distal access catheter clearly showed the perforating arteries arising from the PCA. Case No 1, a 49-year-old woman, was successfully treated with preservation of a(More)
Parietal foramina (PFs) are openings of fine canals that perforate the parietal bone. However, few studies have investigated the entire canals and their emissary vessels (EVs). Here, we explore the EVs with magnetic resonance imaging. A total of 104 patients who underwent contrast examinations and exhibited an intact scalp, skull, dura mater, and superior(More)
