[Takayasu's disease. Detection of the early systemic stage of the disease in a pregnant woman].

The authors describe the case of Takayasu's disease detected in the non-obliterating systemic stage. The disease developed in a 24-year-old woman in the 8th month of gestation and was associated with severe pain of the back and upper extremities, subfebrile temperatures, later fever and tachycardia. The authors describe the difficult diagnosis of the disease and discuss the relationship of the case with so-called fever of unknown aetiology and the development of the disease during pregnancy.
