Laparoscopic resection of an adrenal pseudocyst

Adrenal pseudocysts are rare cystic lesions surrounded by a layer of fibrous tissue that lacks epithelial or endothelial cells. Patients with adrenal pseudocysts may be asymptomatic or present with abdominal pain or other gastrointestinal symptoms. We present the case of a morbidly obese 41-year-old woman who presented with left flank pain. A computed tomography scan of the abdomen and pelvis discovered an 8-cm adrenal lesion. The lesion was hormonally inactive and a transperitoneal laparoscopic left adrenalectomy was performed to exclude malignancy. Pathology discerned multiple pseudocysts with and without calcifications. The patient was discharged on postoperative day 2. She has been asymptomatic in terms of left flank pain for 12 months. We report this case in detail and briefly review the literature regarding adrenal pseudocysts.
