Two hydatid cysts in the psoas muscle of a 40-year-old female: A rare case report

Hydatid disease can affect any human organ. The occurrence of hydatid cysts in psoas muscle is rare, accounting for only 1–3 % of cases, and even in endemic regions. However, the presence of multiple cysts is even more rare. A 40-year-old female from a rural area presented with abdominal pain. Physical examination revealed tenderness in the right hypochondrium. Her medical history pulmonary hydatid cystectomy seven years ago. Radiology investigation showed a two-hydatid cyst within the left psoas major muscle. Cystectomy of two hydatid cyst was performed. The patient was prescribed albendazole at a dose of 15 mg/kg, and at the latest month's follow-up appointment, the patient did not experience any relapse. This case presents a rare instance of multiple hydatid cysts in the psoas muscle, highlighting the importance of considering atypical presentations in endemic regions. This case highlights the rarity of psoas major muscle hydatid cysts in a middle-aged woman from a rural area. Early recognition, accurate radiological assessment, and proper surgical treatment are crucial for positive outcomes and averting complications like infection, compression of nearby structures, or anaphylactic reactions. •Hydatid cysts in the psoas muscle account for only 1-3% of cases, even in regions where the disease is prevalent.•The presence of multiple cysts in the psoas muscle is even rarer.•Further research is required to comprehend the factors behind hydatid cysts in uncommon organs and improve treatment methods.
