Due to the superior sensitivity of contrast-enhanced ultrasound (CEUS) for blood flow compared to other imaging modalities, CEUS was able to demonstrate complete absence of enhancement within the lesion, consistent with tumefactive sludge rather than solid tissue, and averting the need for additional cross-sectional imaging. Surgical pathology following cholecystectomy confirmed these findings.

These complications can range from simple issues to life-threatening ones. Port catheter fractures are rare complications, occurring in less than 1% of patients. The most common complaint in the present study was pain at the site of the subclavian vein puncture when fluid was administered from the port hub. Simple imaging such as chest X-rays can reveal the presence of the catheter fracture and migration. Pinch-off syndrome (POS) is one of the most significant causes of this condition. It is characterized by the catheter fracture compressed between the clavicle and the first rib. The incidence of POS ranges from 0.4% to 5%, with the clinical presentation varying widely from asymptomatic cases to serious complications such as cardiac arrhythmias, pulmonary embolism, or septic embolization. Early diagnosis is critical in preventing the life-threatening outcomes of POS. Diagnosis is usually made through imaging techniques such as chest X-rays, fluoroscopy, and thoracic computerized tomography (CT). Treatment of fracture due to POS typically involves the removal of catheter fragments using an endovascular technique, which offers lower morbidity compared to surgical methods. Prevention strategies include preferring internal jugular vein access over the subclavian vein, placing the subclavian entry point laterally, and performing regular imaging to detect POS symptoms early in the postprocedure period. This case series addresses case-based experiences where fractured port catheter fragments were successfully removed using endovascular methods also discussing the diagnostic and treatment process.</div></div>","PeriodicalId":53472,"journal":{"name":"Radiology Case Reports","volume":"20 6","pages":"Pages 2962-2969"},"PeriodicalIF":0.0,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143705206","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}

Isolated facial nerve palsy resulting from temporal bone metastasis is another rare phenomenon. Metastatic papillary thyroid carcinoma may have unusual manifestations, such as spinal cord compression due to bone metastases and palsy of the seventh cranial nerve. A 35-year-old female patient presented to the emergency department with gradual onset left-sided facial palsy, known to have a goiter. Nevertheless, she did not seek consultation until after experiencing left-sided facial weakness. On leading questions, the patient complained of weakness around the left eye, weakness around the angle of the mouth on the left side, left-sided earache, and hearing loss. The patient also complained of dysphagia, difficulty in breathing associated with excessive sweating, and a history of significant weight loss.Her CT neck and Neurological imaging were done, suggesting a solid lesion in the right lobe of the thyroid gland and a mass causing lysis of the left temporal bone and involvement of the facial nerve, respectively. A thyroid gland biopsy was taken and was suggestive of papillary thyroid carcinoma.
