Abstract:
A 37-year-old man was admitted to hospital for treatment of perineum damage and haematoma in the scrotum. His consciousness deteriorated after two intramuscular injections of pentazocine 15 mg. Faint low signals in the left putamin to frontal island and frontal lobe and obnubilation of the corticomedullary junction were apparent on head CT, which led to suspicion of cerebral infarction. MR angiography showed bilateral obstruction of the middle cerebral artery and moyamoya disease was diagnosed. Treatment with edaravone, argatroban and heparin was ineffective for opening the middle cerebral artery and serious after effects occurred. This case suggests that cerebrovascular accident should be suspected in a young patient with disturbance of consciousness but stable breathing and circulation, particularly if previous drug treatment has affected brain circulation. Moyamoya disease should be suspected based on medical or family history. In such a case, MR angiography is required for early diagnosis to facilitate treatment by re-establishment of blood circulation.
Insights
A young man
Area of Science:
- Neurology
- Vascular Neurology
- Radiology
Background:
- A 37-year-old male presented with perineal trauma and scrotal hematoma.
- Patient experienced a decline in consciousness following pentazocine injections.
Observation:
- Cerebral infarction was suspected due to CT findings of low signals in the left putamen, frontal lobe, and corticomedullary junction.
- MR angiography revealed bilateral middle cerebral artery obstruction, leading to a diagnosis of moyamoya disease.
Findings:
- Medical treatment with edaravone, argatroban, and heparin failed to restore blood flow in the middle cerebral arteries.
- The patient suffered severe adverse effects.
Implications:
- Cerebrovascular accident should be considered in young patients with altered consciousness, especially after drug administration affecting brain circulation.
- Moyamoya disease diagnosis requires suspicion based on history and confirmation via MR angiography for timely intervention.
- Early diagnosis and re-establishment of blood circulation are crucial for managing moyamoya disease and preventing severe outcomes.
