Spontaneous Cerebral Air Embolism-An Unusual Scenario

The introduction of air into cerebral venous or arterial circulation known as cerebral air embolism (CAE) is a rare clinical entity. CAE is commonly iatrogenic secondary to central venous catheter (CVC) placement or removal, various endoscopic procedures, or trauma or surgical scenarios. Here we report a case of spontaneous CAE in an unusual scenario. A 71-year-old male presented to emergency after developing giddiness following a yoga session. His MRI showed air embolism in the posterior fossa along cerebellar folia, prepontine, and suprasellar cisterns and tracking superiorly along the tentorium cerebelli. CAE is a rare clinical entity. Our case had CAE as a complication of cholesteatoma and possibly got triggered due to change in air pressor dynamics during yoga session.
