A 29-year-old patient attended our institution for recurrent strokes related to a giant partially thrombosed M1 aneurysm. Superficial temporal artery-middle cerebral artery (STA-MCA) bypass and subsequent occlusion of both the aneurysm and the dysplastic M1 segment were planned. However, owing to the shortness of the non-dysplastic segment of M1 and the risk of occlusion of the lenticulostriate arteries, the use of a double-lumen balloon was considered for coiling and subsequent injection of Onyx. ⋯ Endovascular occlusion of both the aneurysm and the parent artery was subsequently performed by means of coils and Onyx-34 that was injected via the Ascent balloon under balloon inflation. No complications were recorded and no stroke was observed on control MRI. The injection of Onyx-34 through a double-lumen balloon under balloon inflation is a quick and safe technique for precise occlusion of a parent artery.

We present two uncommon underlying causes of a sore throat which, if missed or delayed in diagnosis, can lead to disastrous consequences. Our first case is of Lemierre's syndrome diagnosed in a 21-year-old man presenting with a 5-day history of sore throat, fever, right-sided pleuritic chest pain and bilateral pulmonary nodules on CT imaging. Fusobacterium necrophorum cultured from peripheral blood and an occluded left internal jugular vein on ultrasound lead to an eventual diagnosis. ⋯ A left-sided quinsy was diagnosed and aspirated and the patient was discharged home. She represented shortly with worsening pleuritic pain and was found to have a right-sided pleural effusion with descending mediastinitis originating from the tonsillar abscess. Delayed diagnosis resulted in open thoracotomy, decortication and prolonged intravenous antibiotics.

Snake bite is an important cause of mortality and morbidity in India with an estimated 35 000-50 000 fatal bites occurring annually. Neurological deficits following vasculotoxic snake bite are either due to intracranial haemorrhage or subarachnoid bleed as a result of consumption coagulopathy. However, ischaemic strokes and acute disseminated encephalomyelitis have been reported occasionally. We hereby report a case of snake bite leading to leucoencephalopathy.

Central venous catheters are commonly used in the management of critically ill patients. This case report described a rare but potentially fatal complication of central venous catheter use. ⋯ On day 8 postoperatively he accidentally removed his catheter and collapsed with symptoms and signs suggestive of a cerebral air embolism. A transthoracic echocardiogram showed air bubbles in both the right and left ventricles of the heart confirming the presence of a paradoxical air embolism.

Percutaneous vertebroplasty is used to treat osteoporotic compression fractures and bone loss due to malignancy. The cement used can serve as a potential nidus for pulmonary thromboembolism (PTE). An 87-year-old woman with recent L2 vertebroplasty presented with abdominal pain and shortness of breath. ⋯ IVC foreign bodies serving as a nidus for PTE have been reported with IVC filters with an incidence of 6.2%. This is the second reported case of vertebroplasty cement serving as a nidus for PTE. Treatment depends on time interval between the procedure and the symptom onset.
