Introduction: The aetiology of non-traumatic intracranial haemorrhage ranges from the common ones like haemorrhagic stroke and aneurysmal rupture to the rare, but nonetheless important causes like haemorrhagic neoplasm and metastasis. In such a wide range of pathologies, imaging findings are very essential in making the diagnosis and thus deciding the course of management to prevent further complications. The objective of our study is to evaluate the role of CT in early diagnosis and establishing the importance of MRI in further characterization across this wide spectrum of presentation in non-traumatic parenchymal haemorrhage. Methods: We retrospectively reviewed cases of non-traumatic cerebral hemorrhage in 20 patients referred for CT and MRI study to our department with proven or almost certain aetiologies for the hemorrhage. We evaluated the clinical presentation and aetiology of the hemorrhage based on multimodality imaging findings. Results: In our sample of 20 cases, the most common cause of non-traumatic haemorrhage was found to be Hypertension, followed by other important causes like Aneurysmal rupture, AV malformation and old infarcts with haemorrhagic transformation, cerebral amyloid angiopathy and cavernoma.
