Infection occurs when individuals ingest eggs from contaminated food or water, leading to cyst formation primarily in the liver. While hydatid cysts are commonly found in various endemic regions, muscular involvement is rare, particularly in the psoas muscle. This report presents a case of a muscular hydatid cyst, describes its management, and emphasizes the need for awareness and prompt intervention. A 50\u2010year\u2010old man presented with abdominal and left lower limb pain, along with weakness over several days. He was febrile, and a physical examination revealed pain during leg movement. Routine laboratory tests were normal. Ultrasound and computed tomography scans identified a solid cystic mass in the left lower quadrant, extending to the left lumbar muscle. After 28\u2009days of preoperative albendazole therapy, the patient underwent surgery through a Rocky Davis incision, where a large hydatid cyst containing daughter cysts in the psoas muscle was discovered. The cyst was unroofed, and its contents were evacuated, followed by irrigation with hypertonic saline. Postoperative recovery was uneventful. He also received standard medication therapy with albendazole, and during monthly visits, no complications were observed during the one\u2010year follow\u2010up. This case contributes to the limited literature on muscular hydatid disease and highlights the importance of awareness among healthcare providers to ensure timely diagnosis and management.<\/jats:p>","DOI":"10.1002\/ccr3.70124","type":"journal-article","created":{"date-parts":[[2025,1,21]],"date-time":"2025-01-21T08:44:26Z","timestamp":1737449066000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Giant Hydatid Cyst Originating From Psoas Muscle Extending to the Iliac Bone: A Case Report"],"prefix":"10.1002","volume":"13","author":[{"given":"Mohammad Hadi","family":"Niakan","sequence":"first","affiliation":[{"name":"Trauma Research Center, Shahid Rajaee (Emtiaz) Trauma Hospital Shiraz University of Medical Sciences  Shiraz Fars Province Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fatemeh","family":"Mirparsa","sequence":"additional","affiliation":[{"name":"Department of Health Policy, Faculty of Health, Scientific Pole of Health Sciences Education, Tehran Medical Sciences Tehran University of Medical Sciences  Tehran Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6790-5910","authenticated-orcid":false,"given":"Hamid Zaferani","family":"Arani","sequence":"additional","affiliation":[{"name":"Department of Surgery Shiraz University of Medical Sciences  Shiraz Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sedighe","family":"Hooshmandi","sequence":"additional","affiliation":[{"name":"Medical Imaging Research Center, Department of Radiology Shiraz University of Medical Sciences  Shiraz Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elham","family":"Peyravi","sequence":"additional","affiliation":[{"name":"Department of Surgery Shiraz University of Medical Sciences  Shiraz Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,1,21]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v18.i13.1448"},{"issue":"1","key":"e_1_2_13_3_1","first-page":"30","article-title":"Review of Hydatid Cyst With Focus on Cases With Unusual Locations","volume":"33","author":"Keser S.
