A Case of a Primary Giant Adrenal Gland Hydatid Cyst—An Exceptional Location: A Case Report

Background and clinical presentation: The adrenal hydatidosis is an exceptional site location for the occurrence of hydatid cyst with an incidence of being 0.073%. We hereby report this rare case of adrenal hydatid cyst in a 38-year-old male who presented with a history of right flank pain and no other associated complaints. On non-contrast computed tomography/high-resolution computed tomography, the whole abdomen revealed the finding of an adrenal hydatid cyst. He underwent laparoscopic right adrenalectomy, which was further confirmed with the pathological examination. In an adjunct to this, he was put on anti-helminthic drug Albendazole. On one year of follow-up, there was no recurrence. Conclusion: The hydatid cyst rarely occurs in the adrenal glands and is an uncommon pathology. It should always be suspected in the case of any cystic tumour of the adrenal gland, especially in endemic countries. The clinical features are variable and non-specific in the majority of the cases. Ultrasonography and CT abdomen hold a significant sensitivity in the diagnosis of the hydatid cyst. Surgical excision is the main choice of treatment. Adjunctive medical treatment improves the outcome and decreases the recurrence rate.
