Shunt surgery is frequently chosen to manage periventricular metastasis of pineal region tumours which obscured the floor of the third ventricle. However, this procedure falls short due to distant metastasis. Neuronavigation-guided endoscopic surgery offers a viable alternative.

Colloid cysts are rare intracranial tumors most commonly found in the third ventricle. We present a case of colloid cyst of the third ventricle that manifested as bilateral advance optic disc cupping, superior hemifield defects in the visual fields and normal intraocular pressure.
Third ventricular cavernous angiomas are rare vascular malformations of the brain. We report an eight-year old boy with a rare third ventricular cavernous angioma that hemorrhaged presenting with symptoms of acute hydrocephalus. Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) showed a heterogenous ill-defined, solid and cystic intraventricular mass in the third ventricle which was mildly enhanced with contrast and there was associated hydrocephalus. The mass was removed with success and follow up after two years revealed no neurological abnormalities.
BACKGROUND: Squamous papillary craniopharyngioma is a distinct entity, and its cytologic features may be misleading. Because of the rarity of this tumor, this case is being reported with a note on the cytologic features.
CASE: A 56-year-old Malay man who had 1-month history of generalized lethargy was admitted for altered sensorium. On examination, he was found to have neck stiffness, bilateral papilledema and generalized atrophy of muscles, with reduced power in all limbs. Magnetic resonance imaging of the brain showed a solid mass in the third ventricle causing obstructive hydrocephalus. Intraoperative cytology of the mass diagnosed intraventricular meningioma. However, the final histopathologic examination revealed squamous papillary craniopharyngioma.
CONCLUSION: Craniopharyngioma, squamous papillary type, is a rare entity and usually occurs in adults as an intraventricular solid tumor. Awareness of this entity will aid in arriving at the correct cytologic diagnosis.
Massive intraventricular hemorrhage (IVH) is nearly always associated with hydrocephalus and is often treated with prolonged external ventricular drainage (EVD); however this procedure can lead to bacterial ventriculitis and meningitis, which can worsen the clinical outcomes. Endoscopic burr hole surgery to remove the hematomas in lateral and third ventricles is an alternative treatment option. We describe the surgical techniques and benefits of endoscopic surgery for acute massive IVH in four patients and discuss the current published literature-related to this condition. Four patients were treated endoscopically for massive IVH. Three patients presented with secondary IVH due to vascular malformation, tumoral bleed and chronic hypertension, while one case presented as massive primary IVH. Endoscopic wash out and removal of hematomas was normally performed together with an endoscopic third ventriculostomy. Recombinant factor VIIa was only administered prior to surgery for IVH secondary to vascular malformation and for cases with postoperative rebleeding which required second endoscopic surgery. Weaning from ventilator and EVD commenced on day 4 postoperatively. All treated patients recovered and did not require further shunt surgery. Good outcomes obtained may be related to early removal of hematomas, creation of new cerebrospinal fluid diversion pathway after thorough wash-out, early weaning from ventilator and EVD. Endoscopic surgery is beneficial in treating poor grade IVH with Graeb score of more than 6.
