Reninoma coexisting with adrenal adenoma during pregnancy: A case report.

Reninoma is a rare form of secondary hypertension. The present study reported a case of reninoma that coexisted with an adrenal adenoma in a young female with secondary hypertension during pregnancy. The patient, a 31-year-old female exhibiting hypertension for >1 year, developed a mass in the right adrenal gland, which was detected by an ultrasound scan in the 33rd gestational week. In addition, a well-defined solid mass on the left kidney was detected by a magnetic resonance imaging scan1 month subsequent to the termination of the pregnancy. The blood pressure (BP) of the patient did not change subsequent to the laparoscopic right adrenalectomy. The patient subsequently underwent laparoscopic left partial nephrectomy 2 months later. The BP levels demonstrated a significant reduction from 177/115 to 125/80 mmHg in the same day postoperatively, and stabilized to be within the normal range. The BP level of the patient remained within the normal range subsequent to a 6-month follow-up. Pathological analysis revealed reninoma on the left kidney. The present study aimed to provide information for radiologists who may encounter this type of benign tumor in the future, which exhibits elevated BP levels.
