As compared with this, true aneurysms contain all three layers: intima, media, and adventitia. Pseudoaneurysms are formed when blood traverses through the intima and media but is held by an adventitial layer. There are several etiologies for the formation of pseudoaneurysms, the most common one being posttraumatic laceration or dissection of the vessel wall. Postprocedural iatrogenic injury during surgery or biopsy is also another common cause for the development of pseudoaneurysms. Vasculitis, regional inflammatory conditions (like pancreatitis causing splenic pseudoaneurysm), and penetrating atheromatous ulcer are among the less common causes. Here, we present a case of a chronic posterior tibial artery pseudoaneurysm following a remote gunshot injury that resulted in extensive transcortical erosion with intraosseous extension and tibial bone transcortical erosion on a 33-year-old male patient with no known prior medical illness. Multimodal imaging including Doppler ultrasound, MRI (with contrast), and CT angiography established the diagnosis after an initial fine-needle aspiration (FNA) attempt led to significant hemorrhage. Only a few cases have been reported on pseudoaneurysms of this size and tibia bone erosion. To our knowledge, full tibial transcortical erosion caused by a chronic posterior tibial artery pseudoaneurysm has not been clearly documented in the literature. This case highlights the importance of early vascular imaging prior to biopsy of pulsatile or indeterminate soft tissue masses.","PeriodicalId":30326,"journal":{"name":"Case Reports in Radiology","volume":"2026 ","pages":"1862171"},"PeriodicalIF":0.0,"publicationDate":"2026-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13247140/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148219947","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}

Laryngeal involvement is rare, and arytenoid cartilage localization is exceptionally uncommon. We present a 46-year-old woman with hoarseness and cough in whom flexible laryngoscopy demonstrated mucosal swelling over the right arytenoid cartilage. Magnetic resonance imaging revealed a 15 × 10 mm lesion that was isointense on T1-weighted images and heterogeneously hyperintense on T2-weighted images, with no diffusion restriction and heterogeneous contrast enhancement. Histopathological examination confirmed the diagnosis of neurofibroma. The lesion was completely excised using a CO2 laser under microlaryngoscopic guidance. The patient's symptoms resolved postoperatively, and no recurrence was observed during follow-up. Although laryngeal neurofibromas lack specific radiological features, magnetic resonance imaging plays a key role in evaluating lesion extent and in supporting the differential diagnosis, particularly by demonstrating the absence of diffusion restriction. To the best of our knowledge, this is the first reported case of an arytenoid cartilage neurofibroma with subglottic extension. Histopathological evaluation remains essential for definitive diagnosis, whereas minimally invasive CO2 laser excision represents an effective treatment option for small and localized lesions.","PeriodicalId":30326,"journal":{"name":"Case Reports in Radiology","volume":"2026 ","pages":"6442641"},"PeriodicalIF":0.0,"publicationDate":"2026-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13239381/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148200187","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}

Lesions were observed in the cervical and thoracic spine and sacrum (C2-C3, C3-C4, C5-C6, T3, T4, T8-T9, S2-S3, and S4 levels) with varying bone involvement, soft tissue extension, and appearance on CT and MRI. The dominant lytic T8-T9 lesion was biopsied, resulting in a diagnosis of chordoma, yet 18F-FDG PET/CT showed no significant FDG activity in this lesion or elsewhere. Other lesions were not biopsied, and all lesions were subsequently monitored with routine imaging. Over the next several years, the lesions continued to show long-term stability on MRI with no symptomatic progression. Due to their longstanding benign nature, the unbiopsied lesions were reevaluated as a more benign etiology, such as benign notochordal cell tumors (BNCTs), which are also derived from notochordal remnants and are hypothesized as a precursor lesion to chordomas, but differ in their clinical behavior, histopathological characteristics, and imaging features. Accurate differentiation between BNCTs and chordomas is imperative for guiding treatment strategies, especially in the very rare case of multiple confounding lesions, as seen in this patient. This report underscores the diagnostic challenges in differentiating BNCTs and chordomas and highlights the importance of correlating histopathological findings with clinical and imaging features for accurate interpretation and intervention.","PeriodicalId":30326,"journal":{"name":"Case Reports in Radiology","volume":"2026 ","pages":"6604031"},"PeriodicalIF":0.0,"publicationDate":"2026-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13168793/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147942860","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}

His medical history included medulloblastoma treated with resection and adjuvant radiation therapy and a WHO Grade 1 meningioma treated with gross total resection. A brain MRI during routine follow-up revealed small enhancing foci in both internal auditory canals (IACs), which prompted concern for bilateral vestibular schwannomas and suspect NF2-related schwannomatosis (NF2-SWN). However, the lesions were symmetric, fundal, and nonnodular on high-resolution constructive interference in steady-state (CISS) imaging, with smooth vestibular nerve contours, long-term interval stability, and a lack of clinical symptoms, favoring physiologic enhancement of the vestibular ganglia (Scarpa's ganglia) rather than vestibular schwannomas. Recognition of these distinguishing features also helped avoid associating the IAC findings with the known NF2 mutation, which was determined to be somatic. While germline NF2 mutations (NF2-SWN) often lead to meningiomas and vestibular schwannomas, somatic NF2 mutations are common in sporadic meningiomas and should not suggest NF2-SWN. This case highlights the need to correlate small enhancing IAC foci with morphology on CISS MRI, symmetry, longitudinal stability, and NF2 pathology to avoid misdiagnosis of enhancing Scarpa's ganglia as vestibular schwannomas, as misdiagnosis can lead to increased patient anxiety and unnecessary follow-ups.","PeriodicalId":30326,"journal":{"name":"Case Reports in Radiology","volume":"2026 ","pages":"1815413"},"PeriodicalIF":0.0,"publicationDate":"2026-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13138210/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147843613","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}

We present a case of a 17-year-old boy who was struck in the abdomen by bicycle handlebars. His initial imaging suggested a possible bladder rupture because of the presence of both intraperitoneal and extraperitoneal fluid. A retrograde CT cystogram, however, ruled out any bladder injury. Because of his worsening condition, he underwent an urgent laparoscopy followed by exploratory laparotomy, which revealed a large volume of milky-white free fluid, suggestive of chyle, within the abdomen. Laboratory analysis of the aspirated fluid showed a high triglyceride level of 1,079 mg/dL, confirming the chylous nature of the fluid. There was an enlarged and engorged cisterna chyli in the retroperitoneum suggesting lymphatic injury. Treatment involved applying fibrin sealant in the region of the cisterna chyli, placing a peritoneal drain, and keeping a diet based on medium-chain triglycerides. The patient recovered well without any recurrence of chylous ascites. This case highlights the need to consider rare lymphatic injuries causing posttraumatic chylous ascites when evaluating blunt abdominal trauma with diffuse abdominal fluid collection, particularly when common injuries have been ruled out but the patient's clinical status continues to worsen.","PeriodicalId":30326,"journal":{"name":"Case Reports in Radiology","volume":"2026 ","pages":"4340538"},"PeriodicalIF":0.0,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13113415/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147783395","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}
