Abstract

Background: Early diagnosis of pheochromocytoma and its proper management can lessen its mortality and morbidity. This case report describes a 24-year-old pregnant woman with an unusual presentation of pheochromocytoma. Case presentation: An Iranian 24-year-old primigravid woman from Kordistan province was referred to our center with left flank pain at 37 weeks of gestation. She had a history of gestational diabetes mellitus since the 12th week of gestation which was managed by insulin administration. She also had a history of pulsatile bi-temporal headache for 2 years prior to her referral to us. She underwent complete abdominal and pelvic ultrasound imaging for her flank pain. This examination revealed a heterogeneous mass of 119 × 87 × 79 mm above her left kidney, highly suspicious of being an adrenal-originating tumor. Subsequently, we consulted an endocrinologist. She underwent abdominopelvic magnetic resonance imaging and her 24-hour urine metanephrine, normetanephrine, and vanillylmandelic acid were assessed. Finally, the diagnosis of pheochromocytoma was confirmed. She underwent a cesarean section and adrenal mass excision at the 40th week of gestation. This timely diagnosis resulted in her proper management and good maternal and neonatal treatment outcomes. Conclusions: Our patient had pheochromocytoma during pregnancy. She had no complaints about hypertension before or during pregnancy until giving birth to her child; her only symptoms were a vague left flank pain, gestational diabetes, and headaches for the past 2 years. The unusual symptom of flank pain led to timely diagnosis and a good treatment outcome. © 2018 The Author(s).
