Adrenal pseudocysts are rare entities, which are usually asymptomatic. Large symptomatic adrenal pseudocysts may cause compressive symptoms. The etiology of these cysts is unknown, although the cyst wall is all lined by fibrous tissue, without any epithelial or endothelial lining. We report a case of a 26-year-old lady who presented with a symptomatic right adrenal pseudocyst measuring 7.6 cm in size. Magnetic resonance imaging confirmed the presence of a right retroperitoneal cystic lesion which was hyperintense on T2 sequencing. An attempted single incision transumbilical laparoscopic surgery (SILS) was performed to excise the right adrenal pseudocyst. However, due to the retro-hepatic nature of the lesion and as the medial wall of the cyst was adherent to the inferior vena cava, an additional 5 mm port was inserted to facilitate retraction of the liver. The post-operative period was uneventful. She was successfully discharged from the hospital as a day surgery patient. The final pathology showed an adrenal pseudocyst.
