While both intramedullary and extramedullary spinal melanomas have been reported, to the best of our knowledge, this is the first noted case of primary spinal melanoma that has both intramedullary and intradural extramedullary components. We present a case of a 61-year-old female presenting with a 1-year history of lower back pain, bilateral lower extremity pain, and perceived weakness of left foot. Magnetic resonance imaging of the thoracic spine suggested intramedullary and intradural extramedullary mass at levels T8-T12. A T7-T12 laminectomy with resection of the spinal cord mass revealed a pathological diagnosis of primary meningeal melanoma. This case highlights the complexity of diagnosing spinal melanomas, which often mimic more common spinal tumours such as ependymomas, astrocytomas, metastasis, or lymphoma. Often meningeal melanomas require extensive imaging and clinical evaluation to exclude other sites of potential primary melanoma. This case adds to the sparse literature by documenting a rare manifestation and could provide valuable insights into the diagnosis and management of similar cases.","PeriodicalId":45216,"journal":{"name":"BJR Case Reports","volume":"11 2","pages":"uaaf020"},"PeriodicalIF":0.5,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11954552/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143755236","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}

This technique is mainly useful for detecting compression fractures; however, studies examining bone tumours have been lacking. Furthermore, no reports to date have investigated the usefulness of MRI for evaluating images before and after radiotherapy (RT) for bone tumours. Therefore, plain CT and MRI (T1/T2-weighted image and CT-like MRI) were performed under the same conditions before and after radiation therapy (RT) and examined the obtained images. An 86-year-old man received RT (30 Gy/3 fraction) for painful lumbar metastasis from prostate cancer. At 2 months after RT, no changes in T2-weighted images and plain CT scans were noted, but CT-like MRI showed an increase in the signal inside the bone metastasis. Examining how the images change over time is imperative given the difficulty of predicting the duration of the pain relief effects of RT for bone metastases. Therefore, the current case report explored whether combining various modalities, such as CT and MRI, could predict prognosis. We highlight the importance of investigating whether signal changes are correlated with pain symptoms and whether MRI can be a predictor.","PeriodicalId":45216,"journal":{"name":"BJR Case Reports","volume":"11 2","pages":"uaaf018"},"PeriodicalIF":0.5,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11968173/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143781544","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}

However, it is well known that mutant IDH1 (mu/IDH1) promotes the accumulation of D2-hydroxyglutarate, an oncometabolite that stimulates tumourigenesis through various secondary, complex metabolic effects. IDH1 and also IDH2 gene mutations have been identified in several types of cancers, such as gliomas, conventional central and periosteal malignant cartilaginous tumours, cytogenetically normal acute myeloid leukaemia, and cholangiocarcinoma. Here, we present 4 cases of Chilean patients with different primary malignant tumours harbouring IDH1. One patient carried the IDH1 p. R132H mutation, the other has IDH1 p. R132L mutation, and the last 2, IDH1 p. R132C mutation. Of note, all these patients had a very poor response to chemotherapy and a rapid disease progression, resulting in a relatively swift death. Next-Generation Sequencing results highlighting mutations in those genes, and other cancer genes were further subjected to in silico study of protein-protein interactions, gene ontology, and pathway enrichment. We also include a state-of-the-art literature review about IDH1 and IDH2 molecular biology, biochemical properties, and the role of their mutations in cancer development and progression, along with insights into regional variations in cancer biology and treatment response.","PeriodicalId":45216,"journal":{"name":"BJR Case Reports","volume":"11 2","pages":"uaaf019"},"PeriodicalIF":0.5,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11968176/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143781548","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}

Vascular injuries from this procedure are extremely rare, with an incidence of 0.003%-1%. Pseudoaneurysms following knee arthroscopy are even less frequent. This paper discusses a rare case of pseudoaneurysm after ACL reconstruction in the articular branch of the right inferomedial genicular artery (IMGA), originating from an anterior tibial artery with a high origin. A 47-year-old man with Von Willebrand disease developed a 24 mm pseudoaneurysm 30 days post-ACL reconstruction. CT-angiography showed the pseudoaneurysm near the tibial tunnel screw and an unusually high anterior tibial artery origin. Emergency angiography confirmed this, and embolization using Squid Peri 18 was successful, with no complications. The patient recovered well. Vascular injury is a rare knee arthroscopy complication, but early diagnosis and awareness of anatomical variations are essential. Endovascular treatment for iatrogenic pseudoaneurysms is safe and effective and facilitates rapid recovery.","PeriodicalId":45216,"journal":{"name":"BJR Case Reports","volume":"11 2","pages":"uaaf014"},"PeriodicalIF":0.5,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12077138/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144081254","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}

This study aimed to evaluate the safety and outcomes of hydrogel spacer placement, specifically SpaceOAR, between the rectum and prostate in prostate cancer patients who had previously undergone radiation therapy. In this retrospective case series, we analysed the medical records of 8 sequential patients undergoing reirradiation in the setting or prior pelvic radiation, who had received transperineal SpaceOAR placement. We documented the incidence of complications after SpaceOAR placement, before and after undergoing radiation therapy. There was a spectrum of complications in this patient cohort, ranging from pelvic pain to more severe complications such as rectal perforation abscess and fistula. Severe complications occurred in 2 of the 8 patients. Re-irradiation may increase the risk of normal tissue complications; however, hydrogel spacer placement using SpaceOAR in prostate cancer patients with prior pelvic radiation was associated with a higher rate of rectal complications than expected in a small series of patients. We urge caution when using SpaceOAR in this patient group.","PeriodicalId":45216,"journal":{"name":"BJR Case Reports","volume":"11 2","pages":"uaaf013"},"PeriodicalIF":0.5,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12041414/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144051576","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}
