Primary Hydatid Cyst of the adrenal gland: A case report and a review of the literature

INTRODUCTION: In North Africa which is an endemic region for Hydatid Cyst, Tunisia is considered as an endemic country. The liver and lungs are common locations for Hydatid Cysts, whereas the Adrenal Glands are unusual and rare locations. PRESENTATION OF CASE: Here is a report of primary Hydatid Cyst in a 55 -year old patient, with left hypochondrium pain as chief complain. No remarkable findings were revealed by physical examination and blood analysis showed normal range. Hydatid serology was negative. The diagnosis of Hydatid Cyst was suspected based on CT Scan results which showed a well-circumscribed, non-enhanced, multicystic, 12 cm mass with scattered calcifications located in the left adrenal gland. Therefore, the patient underwent an open surgery with resection of the protruding dome of the cyst as it was attached to the renal pedicle, the pancreatic tail, the spleen and the jejunum. The final pathological examination of the specimen led to a Hydatid Cyst. DISCUSSION: Throughout an extensive literature review that we have made, we have analyzed 54 reported cases, with their clinical presentations, biological exams, radiological features and surgical managements. The treatment should be surgical and has to be as conservative as possible. The prevention of the parasite transmission has to be the cornerstone of the disease management. CONCLUSION: The hydatid cyst of the adrenal gland remains a rare diagnosis that has to be evoked in case of an adrenal gland cyst, especially in an endemic country. (C) 2020 The Author( s).
