An intracranial cyst tumor with a mural nodule can be representative of some types of brain tumors, but is a rare presentation of intracranial inflammatory myofibroblastic tumor (IMT). Herein, we report the case of an intracranial IMT in a 48-year-old woman presenting with the extremely unusual radiologic findings of a cyst with a mural nodule.

Intracranial cystic lesions such as hemangioblastoma (HB) are commonly found incidentally; however, they can be difficult to diagnose because they require various differential diagnoses. A contrast-enhanced mural nodule on magnetic resonance imaging (MRI) is typical and can be diagnosed preoperatively; however, some small nodules cannot be visualised and only cysts may be seen, complicating preoperative diagnosis. In such cases, thorough observation of the cysts is necessary for a definitive diagnosis.

Article Synopsis
  • - Oesophageal duplication cysts are rare congenital malformations that can cause symptoms like difficulty swallowing, stomach pain, or respiratory issues, and may lead to serious complications requiring surgery.
  • - A 55-year-old woman underwent various imaging tests that showed a tumor near the oesophagogastric junction, leading to a decision for laparoscopic surgery to remove it, which confirmed it was a non-malignant mucinous cyst.
  • - Due to the uncertain relation between the cyst and the oesophageal wall, more extensive surgery (lower oesophagectomy and proximal gastrectomy) was performed instead of just removing the cyst.

Article Synopsis
  • A study was conducted on patients who had surgery for high-risk intraductal papillary mucinous neoplasms (IPMNs) that included a mural module, focusing on the relationship between dysplasia grade and the mural module location.
  • The research involved 82 patients, revealing that nearly half had high-grade dysplasia or invasive carcinoma away from the mural module, indicating that local treatment might not be safe or effective.
  • The results suggest that pancreatectomy (removal of part or all of the pancreas) remains the best treatment option due to the potential risks associated with localized treatments.

Because more than a few patients have intraductal papillary mucinous neoplasms of the pancreas (IPMNs) with mural nodules (MNs) that are benign, clinical plans should be determined by using histocytological specimens especially, for patients with high risk for surgery or with a small MN. This study included 27 patients to evaluate the efficacy of peroral pancreatoscopy using a SpyGlass DS system (POPS-DS) for patients with MN-positive IPMN, mainly focusing on the ability of POPS-DS to detect malignancy. Biopsy specimens obtained under POPS-DS guidance could be used for histological evaluation of all patients with MNs in the main pancreatic duct and 67% of the patients with MNs in the branch ducts, whereas fluid specimens collected during POPS-DS could be used for histocytological evaluation for all patients.

Objective: To establish a classification system which differentiates cystic intraductal papillary neoplasm of the bile duct (cystic IPNB) from hepatic mucinous cystic tumors (MCN) based on their radiological difference.

Methods: A total of 75 patients pathologically diagnosed as MCN and IPNB in two major hospitals from 2015 to 2024 were enrolled. Radiological features were recorded and compared between these two tumors.
