Positive direct antiglobulin test associated with echinococcosis: a case report.
A patient with hydatid cyst of the liver was found to have a positive direct antiglobulin test, with IgG and complement on his red blood cells (RBCs), but with no evidence of haemolysis. The positive direct antiglobulin test disappeared following surgical removal of the cyst. To the best of our knowledge no such case has been reported in the literature.
