First case report of serous otitis media as a complication of severe ovarian hyperstimulation syndrome: Case report and literature review

Ovarian hyperstimulation syndrome (OHSS) may be a severe complication of controlled ovarian hyperstimulation during assisted reproductive technology. During OHSS, fluid shifts from the intravascular space to the third‐space compartments as the result of an increase in capillary permeability. This can cause fluid accumulation in peritoneal as well as thoracic cavities. The patient presented with symptoms of severe OHSS (bilateral hydrothorax and pulmonary effusion), requiring bilateral ultrasound‐guided paracentesis and bilateral thoracentesis during her Emergency Room visits and hospitalization. Due to distant effects from the increased capillary permeability, the patient presented fluid in the middle ear, which led to the development of serous otitis media 12 days after egg retrieval. This was resolved 2–3 weeks later after being treated with antihistamines and antibiotics given by her Ear, Nose, and Throat doctor. OHSS risk may be reduced by continuous monitoring of patients undergoing ovulation induction, using an appropriate gonadotropin dosage, and using additional agents known to decrease its risk. If OHSS still occurs, symptomatic treatment and a multidisciplinary team of professionals may be needed to prevent fluid build‐up complications. In contrast to many published articles about OHSS and its complications, this is the first case report of a patient presenting serous otitis media as a complication of severe OHSS. Synopsis Distant effects from the increased capillary permeability due to OHSS caused fluid in the middle ear and ear plugging, leading to serous otitis media.
