A neonate presented at 26 h of life with poor respiratory effort and lethargy. She was intubated and was put on mechanical ventilation. Radiograph of the neonate suggested malpositioned endotracheal tube. The fluoroscopic dye-study indicated gastroesophageal oesophageal reflux disease and nothing significant. On limited CT contrast study of thorax, a tubular structure was seen running just parallel to the oesophagus extending from the T2 to the T9 levels. Possibilities of a oesophageal duplication/IED were considered. The neonate underwent an endoscopy and gastrostomy on day of life (DOL) 9. On follow up at 3 months a repeat limited CT study was done with instillation of water-soluble contrast. The previously seen tubular structure running parallel to the oesophagus was no longer seen. This finding suggested a healed IED. This case report emphasizes the significance of multimodality imaging in the diagnosis of this condition.","PeriodicalId":45216,"journal":{"name":"BJR Case Reports","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11486540/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142477230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seizures are a common clinical presentation in NKH, and they tend to respond better to glucose correction than anticonvulsant therapy. MRI scans may reveal both subcortical T2/fluid-attenuated inversion recovery (FLAIR) imaging hypointensity and cortical changes, including cortical grey matter T2/FLAIR imaging hyperintensity and cortical or leptomeningeal enhancement, although cortical abnormalities are less frequently observed. These alterations are reversible when the underlying metabolic disturbance is effectively addressed. We suggest the role of iron accumulation as a mechanism for subcortical T2 hypointensity using T2* weighted imaging. Our cases substantiate the significance of subcortical T2/FLAIR hypointensity as a fundamental feature of this condition. In the appropriate clinical context, the recognition of these MRI abnormalities can help prevent misdiagnosis and facilitate timely treatment.","PeriodicalId":45216,"journal":{"name":"BJR Case Reports","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11412579/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142298084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Only approximately 200 cases have been reported to be of adrenal origin to date, and only a few reports about its radiological findings have been published so far. Herein, we present the CT and MRI findings of an adrenal oncocytoma observed in a patient suspected of having mitochondrial abnormalities, along with the pathological findings. The tumour was roughly classified into three areas: a hypercellular region, a region containing fibrous tissue, and an oedematous region. These corresponded to the restricted diffusion area on the apparent diffusion coefficient map, the gradually enhanced area at the secretory phase on contrast-enhanced CT scan, and the obvious hyperintensity on the T2-weighted image, respectively. We also discuss these findings in the context of previously reported radiological findings in the literature. Diagnosing adrenal oncocytoma through imaging is challenging, and it is crucial to consider the possibility of malignancy while making the differential diagnosis. Small-sized homogenous tumours may be hard to differentiate from lipid-poor adenomas, while larger inhomogeneous ones are hard to distinguish from adrenal cancer.","PeriodicalId":45216,"journal":{"name":"BJR Case Reports","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11377097/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142141351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although SMA stenting has been reported to be useful for SMA dissection and stenosis caused by atherosclerotic plaque, SMA stenting for stenosis caused by malignant tumour invasion is rarely reported and uncertain. A 75-year-old woman presented intestinal ulcer and melena caused by SMA invasion of unresectable pancreatic cancer. The bare metal stent was implanted for the vessel stenosis, and a small intestinal ulcer was markedly improved after stenting. However, one and a half months after stenting the stent was occluded and a thrombectomy was performed. After thrombectomy, residual stenosis caused by tumour invasion was observed in the stent. The patient suddenly died 2 days after thrombectomy before additional covered stenting for residual stenosis. Stent implantation may be a treatment option for intestinal ischaemia caused by vessel invasion of malignant tumours. On the other hand, re-stenosis of the stent due to tumour ingrowth is a problem, and covered stenting is considered for long-term stent patency.","PeriodicalId":45216,"journal":{"name":"BJR Case Reports","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11368407/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142126913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These individuals also have no evidence of prior neurological symptoms associated with inflammatory demyelination and no alternative explanation for the observed MRI findings. Recently, the introduction of novel imaging techniques such as the \"central vein sign\" has improved lesion specificity for MS. In addition, the observation of T2-fluid attenuated inversion recovery (FLAIR) mismatch characteristics associated with gliomas and in those with MS with a higher disease burden appear to provide morphological data that relate to disease severity. The value of T2-FLAIR mismatch characteristics in discrete multi-focal lesions has not yet been well defined. Here, we present the value of a fat-suppressed T2-FLAIR sequence in the identification and characterization of T2-weighted hyperintensities resulting from inflammatory demyelination.","PeriodicalId":45216,"journal":{"name":"BJR Case Reports","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11344588/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142056823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
