[A 55-year old Thai male patient with acute right upper quadrant abdominal pain]. / Akute rechtsseitige Oberbauchschmerzen bei einem 55-jährigen thailändischen Patienten.

We report on a 55-year-old Thai male who presented during a visit to Germany with acute abdominal pain in the right upper quadrant and signs of cholestasis. The diagnosis of liver fluke infection (opisthorchiasis) was confirmed by the detection of the characteristic eggs of Opisthorchis viverrini in stool microscopy. The patient was treated with praziquantel. Opisthorchiasis is a common parasitic disease and major public health problem in Southeast Asia and in Eastern Europe.
