One of these is the formation of a triangular, anechoic defect of the uterine myometrium at the site of a previous cesarean section scar, referred to as a niche. This condition may lead to abnormal bleeding, pain, fertility problems, and complications in subsequent pregnancies. This paper presents the case of a 33-year-old patient with a history of two cesarean sections, in whom ultrasonographic examination revealed a defect within the scar measuring 4 mm in depth, consistent with a so-called niche. The patient expressed an intention to conceive again; however, the presence of the defect constituted a significant risk factor for complications during pregnancy. The importance of accurate diagnosis and appropriate management of the niche before a planned pregnancy was emphasized to minimize the risk of serious complications, such as uterine scar dehiscence. This case highlights the need for proper management of women with a cesarean section scar who are planning subsequent pregnancies.<\/jats:p>","DOI":"10.36740\/merkur202603118","type":"journal-article","created":{"date-parts":[[2026,7,12]],"date-time":"2026-07-12T11:11:10Z","timestamp":1783854670000},"page":"375","source":"Crossref","is-referenced-by-count":0,"title":["Case report of a 33-year-old patient with a niche in a cesarean section scar"],"prefix":"10.36740","volume":"54","author":[{"given":"Katarzyna","family":"Woroniecka","sequence":"first","affiliation":[{"name":"FACULTY OF MEDICINE, MEDICAL UNIVERSITY OF BIALYSTOK, BIALYSTOK, POLAND"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomasz","family":"Sk\u0142odowski","sequence":"additional","affiliation":[{"name":"FACULTY OF MEDICINE, MEDICAL UNIVERSITY OF BIALYSTOK, BIALYSTOK, POLAND"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan Hugo","family":"Chudzik","sequence":"additional","affiliation":[{"name":"FACULTY OF MEDICINE, MEDICAL UNIVERSITY OF BIALYSTOK, BIALYSTOK, POLAND"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Micha\u0142 Kacper","family":"Ry\u0144","sequence":"additional","affiliation":[{"name":"DEPARTMENT OF GYNECOLOGY AND GYNECOLOGIC ONCOLOGY, UNIVERSITY CLINICAL HOSPITAL IN BIALYSTOK, BIALYSTOK, POLAND"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wiktoria Izabela","family":"Gula","sequence":"additional","affiliation":[{"name":"FACULTY OF MEDICINE, MEDICAL UNIVERSITY OF BIALYSTOK, BIALYSTOK, POLAND"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jakub Janusz","family":"Jeka","sequence":"additional","affiliation":[{"name":"FACULTY OF MEDICINE, MEDICAL UNIVERSITY OF BIALYSTOK, BIALYSTOK, POLAND"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia","family":"Dmowska","sequence":"additional","affiliation":[{"name":"FACULTY OF MEDICINE, MEDICAL UNIVERSITY OF WARSAW, WARSAW, POLAND"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"22436","published-online":{"date-parts":[[2026,7,1]]},"reference":[{"key":"ref0","doi-asserted-by":"crossref","unstructured":"1.
