Left ventricular pseudoaneurysm is a rare complication of myocardial infarction or cardiac trauma. We report a case of sudden death from rupture of such a lesion. Clinically, these lesions need to be distinguished from the other ventricular out-pouching lesions (true aneurysms and diverticula) because of their greater likelihood for rupture. Pathologically, apart from often being infarct-related, they are characterized by a narrow connection with the ventricular cavity and a fibrous outer wall that is devoid of myocardial tissue.

Primary malignant B-cell-type dural lymphoma is a rare subtype of primary central nervous system lymphoma (PCNSL). We herein report an unusual case of diffuse B-cell lymphoma that presents as a chronic subdural haematoma without extracranial involvement. The notable aspects of this case include the patient's immunocompetence, a short clinical history of symptom onset, rapid neurological deterioration and a fi nal diagnosis of high-grade PCNSL. This case highlights the challenges neurosurgeons face, especially in the emergency setting, when the disease manifests in varied presentations.
