A Case of Cobra Bite Complicated with Basilar Artery Occlusion.

Snakebite is one of the most common complaints related to wilderness medicine. Venomous snakebite manifestation is divided into local and systemic envenomation. For the group, the most feared complication is respiratory muscle paralysis due to neurotransmitter malfunction at the neuromuscular junction level which leads to respiratory insufficiency.

Tumefactive demyelinating lesions versus CNS neoplasms, a comparative study.

Background: Differentiating tumefactive demyelinating lesions (TDL) from neoplasms of the central nervous system continues to be a diagnostic dilemma in many cases.

Objective: Our study aimed to examine and contrast the clinical and radiological characteristics of TDL, high-grade gliomas (HGG) and primary CNS lymphoma (CNSL).

Method: This was a retrospective review of 66 patients (23 TDL, 31 HGG and 12 CNSL).

Unusual presentation of lung carcinoma with pituitary metastasis: a challenging diagnosis and sodium management dilemmas.

Summary: Pituitary metastasis (PM) is a rare complication of an advanced malignancy. Albeit rare, PM can be more detected and achieve a longer survival rate through frequent neuroimaging and newer oncology therapies. Lung cancer is the most frequent primary site, followed by breast and kidney cancers.

Tumour-like presentation of brainstem tuberculoma: a lesson learnt.

Brainstem tuberculoma is diagnostically challenging as it lacks clinical clues and imaging mimics a high-grade glioma (HGG). We report the case of an adolescent girl diagnosed with brainstem HGG, who was referred to our centre for Gamma Knife. Initial MRI showed a pontomedullary junction, ring-enhancing lobulated lesion demonstrating distinct central hypointensity on T2-weighted (T2W) and fluid-attenuated inversion recovery (FLAIR) images with extensive vasogenic oedema.
