Incidental diagnosis of intraductal papillary neoplasm of the bile duct: Imaging findings from a case report.

Intraductal papillary neoplasms of the bile ducts (IPNBs) represent a rare biliary tract tumors with malignant potential, requiring surgical resection to prevent progression to cholangiocarcinoma. In this case, an 83-year-old woman with an obstructive pattern in liver function tests was incidentally found to have a solid mass in the left hepatic lobe on ultrasound. Liver MRI suggested a polypoid intraductal papillary neoplasm of the left bile duct, and histopathological analysis after surgical resection confirmed low-grade dysplasia with a pancreaticobiliary subtype.

Baseline predictors of poor clinical outcome despite recanalization of distal middle cerebral artery occlusions.

ObjectiveMechanical thrombectomy (MT) is well-established for the treatment of acute ischemic stroke (AIS) from large vessel occlusion (LVO), with growing data supporting the expansion to distal and medium vessel occlusions (DMVO). Despite successful recanalization in DMVO, certain patients still experience poor long-term clinical outcomes, prompting our study to comprehensively explore pre-MT factors influencing outcome despite excellent recanalization (final modified Thrombolysis in Cerebral Infarction [mTICI] score ≥2c).MethodsWe retrospectively examined data from patients who consecutively underwent MT for a primary middle cerebral artery (MCA) DMVO across 37 centers in North America, Asia, and Europe.
