This young adult male patient collapsed on an international flight.
A cerebral CT was performed for ongoing reduced level of consciousness.
An abdominal CT was performed.
The radiological findings are:
Bilateral globus pallidus hypodensity consistent with hypoxic brain injury.
Rounded heterogeneous structures in stomach and bowel (drug packets).
The “knot sign” – an eccentric low density nodule on the drug packet, representing the knot in the condom.
These findings together suggest drug packet rupture followed by collapse, hypoxia and subsequent brain injury.
