A 61-year-old man who had undergone total nephrouretectomy eight months earlier for right ureteral carcinoma was referred for the investigation of elevated serum hepatobiliary enzymes. Computed tomography revealed a small mass invading the lower bile duct. Duodenoscopy revealed a central ulcerative tumor near the major papilla, and a biopsy histologically confirmed metastatic ureteral carcinoma. Endoscopic biliary stenting ameliorated the cholangitis, and gemcitabine-based chemotherapy was initiated. The patient was stable for a year until a duodenal stenosis developed and required duodenal stenting...

Mucosa-associated lymphoid tissue lymphoma is a common type of primary pulmonary carcinoma, but the presence of polypoid nodules is extremely rare. We herein report two cases with multiple nodules in the trachea. One case involved polypoid nodules and airway stenosis mimicking asthma; the other case had concurrent nontuberculous mycobacterial infection. The diagnosis of both cases was confirmed by bronchoscopy. The two cases were sensitive to radiotherapy and chemotherapy, respectively.

BACKGROUND: Rotational vertebral artery occlusion is a rare syndrome characterized by vertebrobasilar insufficiency secondary to position-dependent occlusion of the vertebral artery. Most cases reported in the literature have been attributed to osteophytic compression, either from the occipital condyle or within the transverse foramen. However, vertebral artery dissection secondary to motion in the setting of anomalous anatomy has not been reported. CASE DESCRIPTION: To the authors' knowledge, rotational vertebral artery occlusion and dissection secondary to anomalous entrance into the transverse foramen has never been reported...

The introduction of transcatheter therapy for valvular heart disease has revolutionized the care of patients with valvular disorders. Pathologic regurgitation or stenosis of the pulmonary valve, right ventricular outflow tract, or a right ventricle-to-pulmonary artery conduit represent emerging indications for transcatheter therapy. To date, minimal literature exists detailing the anesthetic management of patients undergoing transcatheter pulmonary valve replacement. In this review, the pathophysiology and indications for transcatheter pulmonary valve replacement and possible complications unique to this procedure are reviewed...

BACKGROUND: The treatment of recurrent esophageal stricture secondary to the ingestion of a caustic agent is an arduous task. Self-expanding esophageal stents may be an alternative to repeated endoscopic esophageal dilations. CASE REPORT: We present the case of a two-year-old male with a severe and long esophageal stricture successfully treated by the combination of dilations and stent placement. After five months of serial pneumatic dilations, three self-expanding nitinol stents internally coated with silicone were introduced through a gastrostomy, covering the entire esophagus...

A 66-year-old male patient presented with symptoms and signs of L4/5 radiculopathy. He was found to be anaemic with elevated inflammatory markers and deranged hepatic enzymes. Imaging revealed lumbar canal stenosis and the presence of pyogenic liver abscesses from which Fusobacterium nucleatum and Streptococcus vestibularis were isolated. The hepatic abscesses were attributed to asymptomatic diverticular perforation. Multiple coexisting incidental infections were discovered, including oesophageal candidiasis, Helicobacter pylori, stool cultures positive for Strongyloides stercoralis, and sputum cultures positive for Enterobacter cloacae, Escherichia coli and Mycobacterium avium Extensive investigations for possible underlying immunosuppression were negative...

Over the last decade, percutaneous intervention for the treatment of aortic stenosis has become commonplace with >300,000 implantations performed worldwide. With this now being an established therapy, focus has shifted to the more intricate challenge of mitral and tricuspid valve disease, where there remains a large population of patients with unmet clinical needs. These complex anatomical structures demand unique approaches to treat a wide range of pathologies involving the valve leaflets, annulus and chordae...

Oesophageal squamous cell carcinomas (SCCs) may be observed as exophytic masses or ulcerative or infiltrative endophytic neoplasms. However, in cattle, there is also an uncommon gross presentation as an annular stenotic thickening of the oesophageal wall. Thirteen cases of annular stenotic oesophageal SCC in cattle grazing in bracken fern (Pteridium arachnoideum) areas are reported. The lesions consisted of endophytic masses, focally extensive, firm and circumferential (annular) in the oesophageal wall. Pronounced wrinkling of the mucosa, with retracted uneven areas and subsequent luminal narrowing (stenosis), was observed in all cases...

BACKGROUND: Structured reporting in cardiac imaging is strongly encouraged to improve quality through consistency. The Coronary Artery Disease - Reporting and Data System (CAD-RADS) was recently introduced to facilitate interdisciplinary communication of coronary CT angiography (CTA) results. We aimed to assess the agreement between manual and automated CAD-RADS classification using a structured reporting platform. METHODS: Five readers prospectively interpreted 500 coronary CT angiographies using a structured reporting platform that automatically calculates the CAD-RADS score based on stenosis and plaque parameters manually entered by the reader...
