Sudden

deterioration due to intra-tumoral hemorrhage of ependymoma of the fourth ventricle in a child during a flight: a case report. Brain magnetic resonance imaging carried out before the last admission reveals hyperintense mass in T2-weighted image filling the fourth ventricle without any evidence of hemorrhage.

Intraventricular

neuroepithelial tumors: surgical outcome, technical considerations and review of literature. A 27-year-old female patient presented with slight headache and intermitting vertigo. Preoperative T1-weighted gadolinium enhanced MRI showing a heterogeneously enhancing intraventricular mass on the ground of the fourth ventricle consistent with an ependymoma (a,b). Postoperative T1-weighted gadolinium enhanced MRI showing complete removal of the tumor through a median suboccipital telovelar approach (c,d). Pathological findings confirmed WHO grade II ependymoma

Magnetic

resonance imaging of pineal region tumours. Ependymoma in a 54-year-old man causing headaches, nausea, vomiting, and hydrocephalus. Sagittal T1-weighted image (a) shows a large lesion involving the pineal gland (arrow), which contains areas of low and intermediate signal. Axial T2-weighted image (b) demonstrates cystic areas within the tumour (*) that have high signal and solid portions (arrow) with mixed intermediate and high signal. Solid portions of the tumour (arrow) show contrast enhancement on coronal T1-weighted image (c). The tumour causes hydrocephalus from compression of the midbrain and cerebral aqueduct, pons and cerebellum

Toddler

refusing to walk. Sagittal T1 MRI without contrast of the brain (left) shows an isointense mass filling and distending the fourth ventricle and exiting it and extending beneath the foramen magnum into the spinal canal. The axial T2 MRI (right) shows the hyperintense mass surrounding the left side of the cervical spinal cord. The diagnosis was ependymoma.
