Craniopharyngioma in the prepontine cistern.

We report a pathologically proved craniopharyngioma in the prepontine cistern. A 50-year-old woman presented with swallowing difficulty for 1 month. She underwent brain MR and CT imaging. T1-weighted, T2-weighted, and contrast-enhanced T1-weighted images showed a large peripheral enhancing cystic mass in the prepontine cistern. Inside the lesion, high signal intensity (SI) on T1 and low SI on T...

Subependymoma of the cerebellopontine angle and prepontine cistern in a 15-year-old adolescent boy.

SUMMARY A case of cerebellopontine angle and prepontine cistern subependymoma in a 15-year-old adolescent boy is presented with a review of the literature. Apparent diffusion coefficient values for subependymoma are reported. Differential considerations for the unusual location of this rare tumor are discussed.

A Case of Ectopic Rathke's Cleft Cyst in the Prepontine Cistern

Right Gaze Palsy and Hoarseness: A Rare Presentation of Mediastinal Tuberculosis with an Isolated Prepontine Cistern Tuberculoma

We describe a previously healthy young man who presented with headaches, diplopia with right lateral gaze palsy, dysphagia, and hoarseness over a 2-month period. Magnetic resonance imaging of the brain revealed a small enhancing mass at the prepontine cistern and chest CT showed a left mediastinal mass. Mediastinoscopy and lymph node biopsy were performed. DNA probe and culture of the biopsy sp...
