UNILATERAL HYDROTHORAX AS A SOLE AND RECURRENT MANIFESTATION OF OVARIAN HYPERSTIMULATION SYNDROME FOLLOWING IN-VITRO FERTILIZATION

Acute unilateral hydrothorax may appear as the sole extraovarian expre ssion of severe ovarian hyperstimulation syndrome (OHSS). This case re port describes two such cases, in one of which the patient developed t his rare complication in two consecutive ovarian stimulation cycles. A wareness is needed for the timely and appropriate diagnosis of this ra re complication that occurs 9-14 days following human chorionic gonado trophin (HCG) administration and may recur in consecutive stimulation cycles. Thoracocentesis and fluid balance maintenance are efficient mo des of therapy resulting in good outcome.
