The incidence of MB ranges from 0.5 % to 16 % in coronary angiography patients. This case report presents a 30-year-old female presented with dizziness, shortness of breath, and chest pain, diagnosed with third-degree AV block. Echocardiography revealed interventricular septal thickening and mild mitral regurgitation. Coronary angiography identified myocardial bridging in the mid LAD artery causing significant systolic stenosis. After ruling out reversible causes, a dual-chamber permanent pacemaker was implanted due to persistent heart block. The patient remained stable postprocedure, with decreasing cardiac biomarkers, and was discharged symptom-free with a follow-up appointment scheduled. MB can lead to serious cardiovascular events, including myocardial infarction and CHB. Clinicians must recognize the risks associated with MB and maintain a high suspicion for CHB to ensure timely management.

This case report details the diagnosis, initial management, and long-term follow-up of a 66-year-old female patient who presented with progressive right gluteal pain. Diagnostic imaging at the initial hospital visit identified a 6.5 cm saccular aneurysm in the right sciatic artery. The patient underwent endovascular repair using a Vascutek Anaconda stent graft limb (Terumo, Florida, USA) via a femoral access. Four years later, a recurrence of the aneurysm was detected at the distal end of the stent graft, measuring 3.5 cm. Endovascular treatment, including stent extension, was successfully performed. The patient was discharged in stable condition with a recommendation for 6-month follow-up imaging. This case underscores the importance of advanced imaging for accurate diagnosis and the efficacy of endovascular techniques in managing PSA aneurysms. The recurrence highlights the need for ongoing surveillance and tailored interventions. This case contributes to the limited literature on PSA aneurysms and offers insights into effective management strategies. It emphasizes that persistent sciatic artery aneurysms require a multidisciplinary approach and careful long-term follow-up, with endovascular techniques, combined with cross-sectional imaging, providing effective management that improves patient outcomes.</div></div>","PeriodicalId":53472,"journal":{"name":"Radiology Case Reports","volume":"20 4","pages":"Pages 1888-1892"},"PeriodicalIF":0.0,"publicationDate":"2025-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11786800/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143082077","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}

In such cases, symptoms of encephalopathy, seizures, and neurological deficits appear shortly after contrast administration. This case report discusses a 90-year-old woman who developed severe CIE after iodine contrast agent administration. The patient underwent contrast enhanced computed tomography (CT) and left lower extremity angioplasty 2 days later. The patient's level of consciousness decreased the day after angioplasty; CT and magnetic resonance imaging (MRI) scans suggested CIE. Although the patient was treated with dialysis, but passed away 2 days after onset. Head CT at the time of onset showed extensive high-density area in the cerebral sulci. However, the distribution was different from typical subarachnoid hemorrhage due to ruptured aneurysm; subsequent MRI showed no evidence of subarachnoid hemorrhage. Therefore, CIE was suspected, rather than hemorrhage. A head dual-energy (DE)-CT, which can non-invasively assess the presence of intracranial iodine, was planned for diagnosing CIE. Although her poor condition made it difficult to performed prior to the death, so postmortem DE-CT was performed and confirmed the presence of iodine intracranially. This case suggests considering CIE in patients who develop impaired consciousness after contrast agents use, even when the contrast agents are not directly injected into cerebral blood vessels. In suspected CIE cases, DE-CT is useful for distinguishing iodine from hemorrhage.</div></div>","PeriodicalId":53472,"journal":{"name":"Radiology Case Reports","volume":"20 4","pages":"Pages 1877-1881"},"PeriodicalIF":0.0,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11786802/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143082173","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}
