Iatrogenic rupture of the left gastric artery during percutaneous endoscopic gastrostomy.

Gastric arterial rupture is a rare but serious and potentially fatal complication of percutaneous endoscopic gastrostomy (PEG). We report a case in which insertion of a needle during PEG caused iatrogenic rupture of the left gastric artery.

Sudden cardiac death caused by a primary intimal sarcoma of the left coronary artery.

Primary sarcoma of a muscular artery is extremely rare. A review of the literature revealed only one report of a sarcoma originating in a coronary artery. We report a case of fatal cardiac infarction caused by an intimal sarcoma originating in the left coronary artery which exhibited immunophenotypic features that were consistent with rhabdomyosarcomatous differentiation.

Sudden death due to undiagnosed intracranial hemangiopericytoma.

A previously healthy 9-year-old Japanese boy with a 4-day history of vomiting and headache died suddenly and unexpectedly. An external examination revealed no abnormalities other than foam around the mouth and nose. An internal examination revealed severe pulmonary edema and hemorrhagic hemangiopericytoma arising from the choroid plexus of the right lateral ventricle.

Fatal hyperthermia associated with excited delirium during an arrest.

An autopsy case of fatal hyperthermia in a state of excited delirium is reported. On a hot summer night a 39-year-old man was suspected of being a rapist, and police officers and several men attempted to arrest him. He vigorously resisted, but after a 20-min struggle he was ultimately forced into a prone position on the ground with his arms and legs restrained by police officers.
