Histopathological findings of endovascular thrombectomy-retrieved specimen reveal cardiac papillary fibroelastoma as the cause of ischaemic stroke.

This case reports a rare proximal left middle cerebral artery occlusion caused by cardiac papillary fibroelastoma (CPF), successfully treated with endovascular thrombectomy (EVT) followed by surgical resection of the cardiac tumour. Histological analysis of the EVT-retrieved specimen matched the mass identified on transoesophageal echocardiogram, confirming the diagnosis of CPF-associated embolic stroke. Early identification of CPF through histopathology likely expedited definitive treatment for this patient, who eventually made a full functional recovery.
