    Abstract:
    INTRODUCTION: The usual endoscopic approach in the management of pineal region tumours consists of inserting the scope into the frontal horn of the lateral ventricle and advancing it through the foramen of Monro into the third ventricle. We report the case of a patient with a pineal tumour on whom we used an endoscopic approach through the ventricular atrium to obtain a biopsy by opening the choroidal fissure. CLINICAL CASE: This young 25-year-old man presented with headache and double vision. Papilloedema and Parinaud's syndrome were found on physical examination. Cranial magnetic resonance revealed a pineal mass and hydrocephalus. We initially performed a third ventriculostomy and a tumour biopsy through a frontal burr hole. The tissue sample was not useful for pathological diagnosis and we decided to perform a second endoscopic biopsy. CONCLUSIONS: The endoscopic approach to pineal region masses, reaching the ventricular atrium through a parietal burr hole and opening the choroidal fissure, makes it possible to take a biopsy using a single endoscopic approach without needing to cross other ventricular structures.
