Spontaneous Resolution of Non Traumatic Chronic Subdural Haematoma Despite Continued Antiplatelet Therapy: A Case Report

Spontaneous resolution of traumatic chronic subdural haematoma (CSDH) has been reported in literature. However, those with non traumatic CSDH are exceedingly rare and none reported with continued antiplatelet therapy where it itself is an aetiological agent for development of non traumatic CSDH. A 50-year-old male presented to us with a non haemorrhagic cerebellar infarct with a concomitant CSDH without history of any trauma. Patient's PT/INR, Bleeding time and Clotting time were normal. Patient was started on antiplatelet therapy (Tablet Aspirin 150 mg OD) for the acute infarct. MR Brain at 1 month showed an increased size of CSDH. However patient denied surgical evacuation hence we continued conservative line of management, however we continued anti-platelet therapy with close neurological and coagulation profile monitoring that remained within normal range throughout the period of observation. CT at 5th month showed complete resolution of CSDH. Patient was on antiplatelet drugs throughout the period of observation. Our case argues about the role of antiplatelet therapy in patients with CSDH with contrary lesions requiring anticoagulation.
