Computed tomography angiography demonstrated proximal\u2010to\u2010mid popliteal artery occlusion. Duplex ultrasonography revealed thrombotic occlusion and a slender tendon crossing the artery, which appeared more conspicuous longitudinally than transversely. Magnetic resonance imaging showed apparent continuity with the main tendon of the medial head of the gastrocnemius, supporting an atypical variant of popliteal artery entrapment syndrome. Surgery was declined. At 3\u2009months, the ulcer had healed, and symptoms improved during medical therapy, although perfusion indices remained abnormal. Longitudinal ultrasonography may facilitate delineation of slender compressive tendons.<\/jats:p>","DOI":"10.1002\/jcu.70441","type":"journal-article","created":{"date-parts":[[2026,10,20]],"date-time":"2026-10-20T04:51:35Z","timestamp":1792471895000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Longitudinal Ultrasonographic Appearance of an Atypical Tendinous Variant of Popliteal Artery Entrapment Syndrome in an Adolescent"],"prefix":"10.1002","author":[{"given":"Zeqing","family":"Zhao","sequence":"first","affiliation":[{"name":"Department of Ultrasound Medicine, State Key Laboratory of Complex Severe and Rare Diseases Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiao","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Ultrasound Medicine, State Key Laboratory of Complex Severe and Rare Diseases Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Ye","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, State Key Laboratory of Complex Severe and Rare Diseases Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9093-5309","authenticated-orcid":false,"given":"Jianchu","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Ultrasound Medicine, State Key Laboratory of Complex Severe and Rare Diseases Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,19]]},"reference":[{"issue":"2","key":"e_1_2_10_2_1","doi-asserted-by":"crossref","first-page":"238","DOI":"10.1016\/j.ejvs.2025.04.022","article-title":"Long Term Outcomes of Non\u2010Operative Treatment for Popliteal Artery Entrapment Syndrome: A Multicentre Study","volume":"70","author":"Ahn J.","year":"2025","journal-title":"European Journal of Vascular and Endovascular Surgery"},{"issue":"7","key":"e_1_2_10_3_1","doi-asserted-by":"crossref","first-page":"513","DOI":"10.1177\/1538574413495466","article-title":"Popliteal Artery Entrapment Syndrome: Ultrasound Imaging, Intraoperative Findings, and Clinical Outcome","volume":"47","author":"Altintas U.","year":"2013","journal-title":"Vascular and Endovascular Surgery"},{"issue":"6","key":"e_1_2_10_4_1","doi-asserted-by":"crossref","first-page":"e759","DOI":"10.1097\/MPH.0000000000001933","article-title":"Thromboangiitis Obliterans (Buerger's Disease) in an Adolescent Male","volume":"43","author":"Chapman S.","year":"2021","journal-title":"Journal of Pediatric Hematology\/Oncology"},{"issue":"10","key":"e_1_2_10_5_1","doi-asserted-by":"crossref","first-page":"E266","DOI":"10.1503\/cmaj.241083","article-title":"Popliteal Artery Entrapment Syndrome in a 20\u2010Year\u2010Old Man","volume":"197","author":"Czikk D.","year":"2025","journal-title":"Canadian Medical Association Journal"},{"issue":"9","key":"e_1_2_10_6_1","article-title":"Popliteal Artery Entrapment Syndrome","volume":"123","author":"H\u00e4fner S.","year":"2026","journal-title":"Deutsches \u00c4rzteblatt International"},{"issue":"2","key":"e_1_2_10_7_1","first-page":"112","article-title":"Severe Ischemia due to Popliteal Artery Occlusion in a Young Patient: Evidence of Type 3 Popliteal Artery Entrapment Syndrome on Doppler Ultrasound","volume":"49","author":"Hamdan R.","year":"2024","journal-title":"Journal des Maladies Vasculaires"},{"issue":"5","key":"e_1_2_10_8_1","doi-asserted-by":"crossref","first-page":"1359","DOI":"10.1007\/s00296-011-2300-5","article-title":"Familial Antiphospholipid Syndrome Presenting as Bivessel Arterial Occlusion in a 17\u2010Year\u2010Old Girl","volume":"33","author":"Jelusic M.","year":"2013","journal-title":"Rheumatology International"},{"issue":"1","key":"e_1_2_10_9_1","doi-asserted-by":"crossref","first-page":"84","DOI":"10.1177\/15385744241276689","article-title":"Popliteal Vein Entrapment as a Rare Form of Popliteal Entrapment Syndrome","volume":"59","author":"Jreij G.","year":"2025","journal-title":"Vascular and Endovascular Surgery"},{"issue":"4","key":"e_1_2_10_10_1","doi-asserted-by":"crossref","first-page":"587","DOI":"10.1016\/S0741-5214(99)70098-4","article-title":"Popliteal Artery Entrapment Syndrome: More Common Than Previously Recognized","volume":"30","author":"Levien L.
