We report a case of sciatic nerve entrapment caused by an anomalous inferior gluteal artery in the deep gluteal region, who presented with persistent right gluteal and posterior thigh pain for more than two years, refractory to multiple conservative treatments. Physical examination demonstrated marked allodynia and a well-defined Tinel-like sign, with radiating symptoms extending to the lower limb, suggesting a peripheral etiology. High-resolution ultrasonography identified an aberrant inferior gluteal artery, which crossed over and compressed the sciatic nerve, forming an accompanying artery of the sciatic nerve. Doppler imaging confirmed the vascular nature of the structure, while long-axis views demonstrated focal nerve compression with segmental swelling. Magnetic resonance imaging further corroborated the diagnosis. Ultrasound-guided hydrodissection using 5% dextrose and lidocaine was performed, resulting in significant symptom relief. Pain scores improved from 7 to 3 after treatment, with resolution of symptoms at two-month follow-up. This case highlights a rare neurovascular cause of sciatic nerve entrapment and underscores the importance of ultrasonography in identifying anatomical variations. Recognition of vascular contributions to deep gluteal syndrome may improve diagnostic accuracy and guide targeted interventions.<\/jats:p>","DOI":"10.3390\/diagnostics16111668","type":"journal-article","created":{"date-parts":[[2026,5,29]],"date-time":"2026-05-29T10:06:56Z","timestamp":1780049216000},"page":"1668","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Unusual Sciatic Nerve Entrapment by the Inferior Gluteal Artery"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7511-9629","authenticated-orcid":false,"given":"Wei-Ting","family":"Wu","sequence":"first","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Community and Geriatric Research Center, National Taiwan University Hospital, Bei-Hu Branch, Taipei 108206, Taiwan"},{"name":"Department of Physical Medicine and Rehabilitation, National Taiwan University College of Medicine, Taipei 100233, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Chun","family":"Hsu","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Community and Geriatric Research Center, National Taiwan University Hospital, Bei-Hu Branch, Taipei 108206, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7558-5651","authenticated-orcid":false,"given":"Ke-Vin","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Community and Geriatric Research Center, National Taiwan University Hospital, Bei-Hu Branch, Taipei 108206, Taiwan"},{"name":"Department of Physical Medicine and Rehabilitation, National Taiwan University College of Medicine, Taipei 100233, Taiwan"},{"name":"Center for Regional Anesthesia and Pain Medicine, Wang-Fang Hospital, Taipei Medical University, Taipei 110301, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2713-4071","authenticated-orcid":false,"given":"Levent","family":"\u00d6z\u00e7akar","sequence":"additional","affiliation":[{"name":"Department of Physical and Rehabilitation Medicine, Hacettepe University Medical School, Ankara 06100, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Wu, W.T., Chang, K.V., Mezian, K., Nanka, O., Ricci, V., Chang, H.C., Wang, B., Hung, C.Y., and Ozcakar, L.
