We report a case of an intraventricular ganglioglioma in a 23-year-old male. The patient presented with a 3-day history of headache and vomiting. Preoperative brain imaging revealed a calcified lesion within the trigone of the right lateral ventricle, with irregular enhancement, causing entrapment of the temporal horn of the lateral ventricle. At surgery, the lesion was haemorrhagic, easily friable and exhibited evidence of a previous recent haemorrhage. Histological and immunohistochemical studies showed a ganglioglioma with World Health Organisation Grade 1 characteristics. Gangliogliomas of the central nervous system are uncommon, and rarely occur in the lateral ventricle., Competing Interests: None declared., (Published by Oxford University Press and JSCR Publishing Ltd. © The Author(s) 2023.)

Central nervous system (CNS) infection and neoplasm occur most often independently. Their concomitant presentation has been noted across different CNS tumours but is considered a rare entity. The phenomenon is mostly seen in relation to direct seeding of infection via frontal air sinuses. Here, we present an unusual case of an occipital meningioma associated with intraparenchymal paratumoural abscess formation. It is also the second documented to culture methicillin-susceptible Staphylococcus aureus . We then review and surmise the relevant literature of meningioma-associated abscess. We discuss the clinical presentations, aetiology, suspected pathogenesis, management and outcomes reported., (Published by Oxford University Press and JSCR Publishing Ltd. © The Author(s) 2022.)
