However, infrequently, tumours are misdiagnosed as subdural haematoma on initial brain CT scans and are only discovered intraoperatively. In this case series, we presented 3 different patients who were initially thought to have subdural haematoma but later found to be tumour mimics of different histological origin. A literature review and discussion of recently published tumour mimics of subdural haematoma was also performed. It is recommended that in patients with suggestive oncological or haematological history, or unusual characteristics on the plain CT brain, a high level of suspicion of tumour mimics needs to be maintained. A full workup with contrast-enhanced magnetic resonance imaging is important to distinguish from subdural haematoma, as the treatment paradigms and prognoses are vastly different.
