Cerebral venous sinus thrombosis (CVST) is a rare disease with occasional fatal outcomes. Superior sagittal sinus (SSS) thrombosis comprises nearly 70%-80% of all CVST cases. Pregnancy and puerperium are known risk factors for CVST. We report the case of a 25year old female patient who developed SSS thrombosis after a normal vaginal delivery. She presented with complaints of headache and vomiting. The relatives of the patient made allegations of head injury incurred from assault in-laws about one week ago followed by suspicion of ingestion of a poisonous substance. Radio imaging revealed gross hemorrhage in the brain and sudden death after admission made the manner of death suspicious. Correlation of clinical history, autopsy examination, pathological findings, and viscera report was helpful to reach the most accurate cause and manner of death. This case is an effort to reinforce the importance of interpretation and analysis of medical findings to aid the legal system.
