A case of a solid cystic tumor (SCT) of the pancreas with massive hemoperitoneum occurring in a 31-year-old woman is reported. She was admitted with abdominal pain and rebound tenderness. Computed tomography (CT) disclosed a large tumor consisting of both solid and cystic components in the body of the pancreas. Within 12 hours after admission, she exhibited exacerbation of pain and hemoperitoneum on CT with deterioration of general condition and anemia. Celiac artery angiography demonstrated the tumor as a hypovascular mass. SCT of the pancreas was suspected, and emergent laparotomy was performed. In the surgical procedure, tumor in the body of the pancreas with rupture was detected. Distal pancreatectomy was performed with removal of the regional lymph nodes. There was no evidence of metastatic disease in the abdomen. The cut surface of the tumor exhibited areas of cystic degeneration containing hemorrhagic friable materials. Microscopically, the tumor cells were mainly cubic or cylindrical peripherally in pseudo-papillary formation. Postoperative recovery was normal and she was discharged on the 15th postoperative day. Three years after operation, she is free of disease without findings of recurrence.

Impact of SARS-CoV-2 spike antibody positivity on infection and hospitalisation rates in immunosuppressed populations during the omicron period: the MELODY study.

Background: In the UK, booster COVID-19 vaccinations have been recommended biannually to people considered immune vulnerable. We investigated, at a population level, whether the absence of detectable anti-SARS-CoV-2 spike protein IgG antibody (anti-S Ab) following three or more vaccinations in immunosuppressed individuals was associated with greater risks of infection and severity of infection.
Methods: In this prospective cohort study using UK national disease registers, we recruited participants with solid organ transplants (SOTs), rare autoimmune rheumatic diseases (RAIRDs), and lymphoid malignancies.

Several artificial intelligence systems based on large language models (LLMs) have been commercially developed, with recent interest in integrating them for clinical questions. Recent versions now include image analysis capacity, but their performance in gastroenterology remains untested. This study assesses ChatGPT-4's performance in interpreting gastroenterology images.

Gastroenterology and Digestive Endoscopy Unit, Forlì-Cesena Hospitals, 47121 Romagna, Italy.
Endoscopic ultrasound (EUS)-guided radiofrequency ablation (RFA) is a promising minimally invasive technique for the treatment of pancreatic lesions. This review first focuses on the technical aspects in EUS-RFA: the procedure typically employs EUS probes with integrated radiofrequency electrodes, enabling accurate targeting and ablation of pancreatic lesions. Different types of RFA devices, monopolar and bipolar energy delivery systems, are discussed, along with considerations for optimal ablation, including energy settings, procedure time, and pre- and post-procedural management.

Department of Neuroradiology, University Hospital Würzburg, D-97080 Würzburg, Germany.
Background: Intracranial choroid plexus tumors (CPT) are rare and primarily affect young children. Leptomeningeal dissemination (LMD) has been reported not only in high-grade choroid plexus carcinoma (CPC) but also in lower histological grades; however, a systematic evaluation of CPT-specific imaging characteristics remains lacking.
Methods: We analyzed the imaging characteristics of LMD in a single-center pediatric cohort of 22 CPT patients (thirteen choroid plexus papilloma (CPP), six atypical choroid plexus papilloma (aCPP), three CPC), comparing LMD features with those of the primary tumor.

Department of Colorectal Surgery, Dingli Clinical College, Wenzhou Medical University (Wenzhou Central Hospital), 252 Baili East Road, Wenzhou, Zhejiang Province, 32500, China.
Background: An association between testicular cancer and Down syndrome has been reported by several studies. Down syndrome with cryptorchidism and retroperitoneal mixed germ cell tumours is rare, and yolk sac tumours are often considered secondary components of mixed germ cell tumours. Herein, we present a rare case of retroperitoneal mixed germ cell tumour with cryptorchidism accompanied by yolk sac tumour and seminoma in a patient with Down syndrome, along with its imaging features.
