The clinical presentation and CT findings in eight patients with pathologically confirmed primary colorectal squamous-cell carcinoma were retrospectively reviewed by two gastrointestinal radiologists. Hematochezia was the most common symptom (n = 5). The tumors were located in the rectum (n = 7) and sigmoid colon (n = 1). The tumors showed circumferential wall thickening (n = 4), bulky mass (n = 3), or eccentric wall thickening (n = 1). The mean maximal wall thickness of the involved segment was 29.1 mm \u00b1 13.4 mm. The degree of tumoral enhancement observed via CT was well enhanced (n = 4) or moderately enhanced (n = 4). Necrosis within the tumor was found in five patients. The mean total number of metastatic lymph nodes was 3.1 \u00b1 3.3, and the mean short diameter of the largest metastatic lymph node was 16.6 \u00b1 5.7 mm. Necrosis within the metastatic node was observed in six patients. Invasions to adjacent organs were identified in five patients (62.5%). Distant metastasis was detected in only one patient. In summary, primary SCCs that arise from the colorectum commonly present as marked invasive wall thickening or a bulky mass with heterogeneous well-defined enhancement, internal necrosis, and large metastatic lymphadenopathies.<\/jats:p>","DOI":"10.3390\/tomography10050052","type":"journal-article","created":{"date-parts":[[2024,5,2]],"date-time":"2024-05-02T12:06:38Z","timestamp":1714651598000},"page":"674-685","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Comprehensive CT Imaging Analysis of Primary Colorectal Squamous Cell Carcinoma: A Retrospective Study"],"prefix":"10.3390","volume":"10","author":[{"given":"Eun Ju","family":"Yoon","sequence":"first","affiliation":[{"name":"Department of Radiology, Chosun University Hospital and Chosun University College of Medicine, Gwangju 61453, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sang Gook","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Radiology, Chosun University Hospital and Chosun University College of Medicine, Gwangju 61453, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4725-5687","authenticated-orcid":false,"given":"Jin Woong","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Radiology, Chosun University Hospital and Chosun University College of Medicine, Gwangju 61453, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyun Chul","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Radiology, Chosun University Hospital and Chosun University College of Medicine, Gwangju 61453, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7591-9079","authenticated-orcid":false,"given":"Hyung Joong","family":"Kim","sequence":"additional","affiliation":[{"name":"Medical Science Research Institute, Kyung Hee University Hospital, Seoul 02447, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Young Hoe","family":"Hur","sequence":"additional","affiliation":[{"name":"Department of Hepato-Biliary-Pancreas Surgery, Chonnam National University Hwasun Hospital and Chonnam National University Medical School, Gwangju 61469, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun Hyung","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Radiology, Chosun University Hospital and Chosun University College of Medicine, Gwangju 61453, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"209","DOI":"10.3322\/caac.21660","article-title":"Global cancer statistics 2020: GLOBOCAN estimates of incidence and mortality worldwide for 36 cancers in 185 countries","volume":"71","author":"Sung","year":"2021","journal-title":"CA Cancer J.
