A 20-year-old male patient was admitted to our clinic with a 1-year history of headache. The patient’s systemic-neurological examination and laboratory findings were normal. Computed tomography and magnetic resonance imaging were performed. Imaging findings showed calcified intraventricular mass and subependymal and gyral nodular lesions. There was a slight increase in ventricular volume. Surgi...

Intraventricular meningiomas require a cautious surgical preoperative planning in an attempt to avoid unwanted postoperative neurological déficits. Despite that better approaches exist, the posterior parietal transcortical approach intraventricular trigonal lesions, with its unavoidable damage white matter pathways, is still popular clinical practice, at times,like following case report, withou...

Cancer in the central nervous system can arise from a primary brain tumor and metastasize to the brain or to the leptomeninges, leading to leptomeningeal metastasis (LM). LM also is called leptomeningeal carcinomatosis and carcinomatous meningitis. When LM occurs, signs and symptoms include headache, nausea, vomiting, lumbar back pain, and stiff or painful neck; LM also may lead to mental distu...

Background. To our knowledge, this is the sixth reported case in the literature of fourth ventricular schwannoma. The etiology and natural history of intraventricular schwannomas is not well understood. A thorough review of potential etiopathogenic mechanisms is provided in this case report. Case Description. A 69-year-old man presented with an incidentally found fourth ventricular tumor during...

Lateral ventricular meningiomas presenting with primary intraventricular hemorrhage are extremely uncommon. We report here a case of primary intraventricular hemorrhage attributable to a lateral ventricular meningioma. This case concerns a 46-year-old female patient who presented with sudden onset of headache. Computed tomography (CT), computed tomography angiography (CTA) and magnetic resonanc...

Choroid plexus carcinoma is an uncommon neoplasm of the central nervous system most commonly found in the pediatric population. It is associated with a dismal prognosis, especially if incompletely resected. Accurate histopathologic diagnosis is imperative, and this neoplasm should always be included in the differential diagnosis of a papillary intraventricular tumor. Histopathologic features in...

Prenatal diagnosis of intracranial tumors generally implies a poor prognosis. We present three such cases, where prognostication was difficult. We attempted to correlate our prenatal counseling with postnatal follow-up/postabortal diagnosis. In the first case, tumor was diagnosed at 37 weeks. Ultrasound and fetal/neonatal MRI suggested a malignant intraventricular tumor. Anticipating guarded pr...

Patients: 601 patients (mean age 64 y, 57% men) who were conscious, had a computed tomography–confirmed spontaneous lobar ICH (volume 10 to 100 mL) ≤ 1 cm from the cortical surface of the brain, and presented ≤ 48 hours after ictus. Exclusion criteria included hemorrhage that was intraventricular, due to arteriovenous malformation confirmed by angiography or an aneurysm, secondary to tumor or t...

Subependymoma is a rare benign slowly growing tumor which usually appears as a well-defined lobulated entirely intraventricular mass, in the fourth or lateral ventricles. We report a case of subependymoma involving the septum pellucidum in a 28 year old female demonstrating a subtle and unusual radiological appearance. It showed very low attenuation on computed tomography, with very high signal...

A 30-year-old man was intubated after sudden severe headache, loss of consciousness, and apnea. CT showed acute hemorrhage in the posterior fossa, brainstem compression, and intraventricular extension with early obstructive hydrocephalus (figure 1A). MRI showed a large heterogeneously enhancing extra-axial tumor extending from the cerebellopontine angle to the foramen magnum (figure 1, B and C)...
