RESUMO
INTRODUCTION AND IMPORTANCE: 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. CASE PRESENTATION: 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. CLINICAL DISCUSSION: This case presents a rare instance of multiple hydatid cysts in the psoas muscle, highlighting the importance of considering atypical presentations in endemic regions. CONCLUSIONS: 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.
