Vascular injuries during pituitary surgery are feared as they can lead to serious disability and can be life threatening. We are describing a case of severe intractable epistaxis following endoscopic transnasal transsphenoidal surgery for pituitary tumour due to a sphenopalatine artery pseudoaneurysm which was successfully managed using endovascular embolisation techniques. Very few cases of sphenopalatine artery pseudoaneurysm following endoscopic nasal surgery have been described. A middle aged male patient with a pituitary macroadenoma underwent endoscopic transsphenoidal pituitary surgery and returned to us after 3 days of discharge with severe epistaxis. Digital subtraction angiography showed contrast leakage and left sphenopalatine artery pseudoaneurysm. Glue embolisation of the distal sphenopalatine branches and pseudoaneurysm was done. Good occlusion of pseudoaneurysm was seen. Such a diagnosis for epistaxis following endoscopic transnasal surgery should be borne in mind, so prompt treatment can be planned to avoid life threatening complications.

Objectives This report seeks to highlight a pitfall that may be encountered in the management of patients with trigeminal neuralgia with imaging showing both neurovascular conflict as well as tumors. Case presentation A case of a 53 year old male with simultaneous neurovascular conflict and a vestibular schwannoma with trigeminal neuralgia is presented and the management is discussed with reference to managing this particular subset. Pain was noted to be likely generated by neurovascular conflict and not by the tumor, which is usually not the case. Conclusions It is suggested that in such cases, microvascular decompression should always be performed in addition to removal of the tumor.

Primary CNS lymphoma (PCNSL) is a rare form of extra nodal Non-Hodgkin Lymphoma that is typically confined to the brain, spinal cord, lepto meninges and eyes. We studied the clinico pathological features of PCNSLs, immuno histochemical (IHC) markers expressed and the association of morphological features & IHC markers with clinical outcome. 30 cases of primary CNS lymphomas were studied. 25 cases were diffuse large B cell lymphomas, which were sub classified using Hans algorithm into GCB and non-GCB. The IHC markers done were CD20, CD3, BCL2, BCL6, MUM-1, CD10 and c-myc. Mean proliferation index Ki was 80%. Follow up and survival data was collected and the association of each IHC marker and subtype with prognosis was assessed. PCNSL forms around 2% of all lymphomas as well as primary CNS tumours. Non GCB type is more common (72%). Mean overall survival was 9.7 months. Ki-67 index of 80% or more is the only independent variable of prognostic significance. None of the other IHC markers or sub typing had any influence on the outcome.
