Spontaneous adrenal haemorrhage in early pregnancy

A 32-year-old primigravida presented at our emergency room at 6 weeks of gestation with acute severe right upper quadrant abdominal pain, radiating to the right flank. Vital signs were stable. Abdominal ultrasound showed a round inhomogeneous mass of 10 cm diameter behind the right kidney, suspected for adrenal haemorrhage. The patient was admitted for observation. An MRI showed some right-sided pleural effusion and a round mass in the adrenal region with no recognisable adrenal gland, therefore most likely originating from the right adrenal. After 10 days the patient was discharged with no change in size of the haematoma. MRI was carried out every 2 months which showed a decrease in size of the haematoma, with no other abnormalities. Based on stable MRI and the patient’s preference, a vaginal delivery mode was chosen. At 37 weeks of gestation labour was induced, followed by an uncomplicated delivery.
