They have visited other doctors for similar presentation in the last 6 months, which started as redness and swelling, with occasional epiphora. The redness resolved after medical treatment, with slight regression of swelling, although it did not disappear. CT and MRI showed a locally aggressive, small enhancing soft tissue mass involving the left anteromedial maxillary wall, the nasal bone and the orbital floor. The mass involved the bony course of the nasolacrimal duct, which was the aetiology of the epiphora. The head and neck team performed an incisional biopsy through a sublabial approach. Concurrently, a nasolacrimal duct stent was inserted by an ophthalmologist. Histopathology was consistent with inflammatory myofibroblastic tumour with positive stains for CD68, CD163 and anaplastic lymphoma kinase-1. The tumour was excised and presently the patient is on periodic follow-up with head and neck and ophthalmology clinics.<\/jats:p>","DOI":"10.1136\/bcr-2020-235532","type":"journal-article","created":{"date-parts":[[2020,10,27]],"date-time":"2020-10-27T17:05:38Z","timestamp":1603818338000},"page":"e235532","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Radiological diagnostic dilemma in a child with small aggressive facial mass, time to increase the differentials: an inflammatory myofibroblastic tumour"],"prefix":"10.1136","volume":"13","author":[{"given":"Waleed Mohamed Samy","family":"Fawzy","sequence":"first","affiliation":[{"name":"Radiology and Medical Imaging, King Saud University Medical City, Riyadh, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adeena","family":"Khan","sequence":"additional","affiliation":[{"name":"Radiology and Medical Imaging, King Saud University Medical City, Riyadh, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Syed","family":"Shahid Habib","sequence":"additional","affiliation":[{"name":"Clinical Physiology, King Saud University Medical City, Riyadh, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammed Abdulmuhsen","family":"Alessa","sequence":"additional","affiliation":[{"name":"ENT, Head and Neck, King Saud University Medical City, Riyadh, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,10,27]]},"reference":[{"key":"2025082801543000000_13.10.e235532.1","doi-asserted-by":"publisher","DOI":"10.1136\/jcp.2007.049387"},{"key":"2025082801543000000_13.10.e235532.2","doi-asserted-by":"crossref","first-page":"261","DOI":"10.4103\/ijmpo.ijmpo_178_16","article-title":"Clinico-radiological and pathological characteristics of inflammatory myofibroblastic tumors in children: a retrospective study","volume":"38","author":"Mir","year":"2017","journal-title":"Indian J Med Paediatr Oncol"},{"key":"2025082801543000000_13.10.e235532.3","doi-asserted-by":"crossref","first-page":"576","DOI":"10.1038\/s41379-019-0406-6","article-title":"Infantile inflammatory myofibroblastic tumors: clinicopathological and molecular characterization of 12 cases","volume":"33","author":"Lopez-Nunez","year":"2020","journal-title":"Mod Pathol"},{"key":"2025082801543000000_13.10.e235532.4","doi-asserted-by":"crossref","first-page":"6794","DOI":"10.3934\/mbe.2019339","article-title":"Inflammatory myofibroblastic tumor: a demographic, clinical and therapeutic study of 92 cases","volume":"16","author":"Fu","year":"2019","journal-title":"Math Biosci Eng"},{"key":"2025082801543000000_13.10.e235532.5","doi-asserted-by":"crossref","first-page":"36","DOI":"10.1016\/j.sdentj.2016.10.001","article-title":"A rare case of inflammatory myofibroblastic tumor of the mandible mimicking a malignant tumor","volume":"29","author":"AlKindi","year":"2017","journal-title":"Saudi Dent J"},{"key":"2025082801543000000_13.10.e235532.6","doi-asserted-by":"crossref","DOI":"10.4103\/0972-124X.134582","article-title":"Inflammatory myofibroblastic tumor of maxilla showing sarcomatous change in an edentulous site with a history of tooth extraction following periodontitis: a case report with discussion","volume":"18","author":"Biniraj","year":"2014","journal-title":"J Indian Soc Periodontol"},{"key":"2025082801543000000_13.10.e235532.7","first-page":"1","article-title":"Inflammatory myofibroblastic tumor of the lung and the maxillary region: a benign lesion with aggressive behavior","volume":"2013","author":"Gallego","year":"2013","journal-title":"Case Rep Dent"},{"key":"2025082801543000000_13.10.e235532.8","doi-asserted-by":"crossref","unstructured":"sultana J et al .
