Symptomatic pseudotumor in Meckel cave mimics trigeminal schwannoma.

Background: Inflammatory pseudotumor is non-neoplastic lesions that form tumor-like masses, typically occurring in the lungs and orbits, with rare involvement of intracranial regions such as the Meckel cave. While neuroimaging can assist in differential diagnosis, definitive diagnosis may remain challenging. Some cases are associated with immunoglobulin G4 (IgG4)-related disease, highlighting the importance of histopathological confirmation to guide appropriate management.

Internal carotid artery dissection presenting with glossopharyngeal nerve dysfunction: A case report.

Background: Internal carotid artery dissection (ICAD) is an uncommon but important cause of ischemic stroke in young adults, particularly in Asian populations where its incidence is relatively low. While ICAD typically presents with headache, neck pain, or ischemic symptoms, it can also lead to isolated cranial nerve involvement, complicating the diagnostic process.

Case Description: We report the case of a 45-year-old woman who presented with isolated right-sided glossopharyngeal nerve symptoms - specifically, ageusia and pharyngeal discomfort - along with mild posterior neck pain.

Two Patients with Large Aneurysms in Whom Coil Embolization with Overlapping LVIS Stents Was Performed.

Objective: We report two patients with unruptured large aneurysms treated by overlapping stent-assisted coil embolization using low-profile visualized intraluminal support (LVIS) stents.

Case Presentation: Case 1: An 80-year-old woman presented with abducens nerve palsy due to an internal carotid artery aneurysm. Case 2: A 75-year-old man presented with a partially thrombosed fusiform aneurysm in the vertebral artery (VA).

Gradual Growth of Spontaneous Dissecting Aneurysm of the Extracranial Internal Carotid Artery After Aneurysmal Subarachnoid Hemorrhage.

Spontaneous dissecting aneurysm of the extracranial internal carotid artery is uncommon, and simultaneous onset of multiple dissecting aneurysms is rare in patients without congenital or traumatic risk factors. A few reports suggest that extracranial internal carotid artery dissecting aneurysms can grow after SAH due to another intracranial dissecting aneurysm. The present report describes two cases in which gradual growth of unruptured dissecting aneurysm of extracranial internal carotid artery occurred after SAH due to ruptured dissecting aneurysm of the vertebral artery and in which carotid artery stenting was subsequently performed.

Intracranial meningioma as initial clinical manifestation of occult lung carcinoma: case report.

Intracranial meningioma with intratumor metastasis have been occasionally reported. However, to our knowledge, there are almost no reports of malignant tumors initially discovered due to metastasis to meningioma. A 74-year-old woman presented with amnesia.
