Rationale: Pancreatic ductal carcinoma is a hypovascular tumor, and characteristic findings are observed on imaging modalities, such as computed tomography (CT) and magnetic resonance imaging (MRI), in most cases.
Patient Concerns: Here we report a case of anaplastic carcinoma of the pancreas (ACP) with characteristics of hypervascular tumor diagnosed by endoscopic ultrasound guided fine needle aspiration (EUS-FNA). A 70-year-old woman was admitted to hospital because of exacerbation of diabetes. Contrast-enhanced CT revealed a hypervascular tumor at the head of the pancreas.
Diagnosis: EUS-FNA was performed. Osteoclast-like giant cells and tumor cells with polymorphic nuclei were found on pathological examination and she was diagnosed with ACP.
Interventions: Although it was a surgical indication at the time of diagnosis, the tumor rapidly worsened. Oral administration of TS-1 (tegafur/gimeracil/oteracil) was initiated. Chemotherapy was discontinued after the end of 2 courses because the tumor had increased prominently on CT.
Outcomes: She died approximately a year since the onset of the illness.
Lessons: ACP occasionally exhibits the characteristics of a hypervascular tumor and may require differentiation from other pancreatic tumors, such as neuroendocrine tumor. Therefore, pathological diagnosis by EUS-FNA at an early stage is important to determine treatment strategies.

Outcomes and Role of Lymphadenectomy in Hypervascular Intrahepatic Cholangiocarcinoma Based on CT-Vascularity.

Background: This study aimed to evaluate the outcomes and role of lymphadenectomy in hypervascular intrahepatic cholangiocarcinoma (ICC) quantified using the arterial phase of contrast-enhanced computed tomography (CT).
Methods: Consecutive patients with mass-forming (MF) or predominantly MF type ICC who underwent surgical resection from 2000 to 2019 were retrospectively analyzed. Using the image of the late arterial phase, CT-vascularity was calculated by dividing the CT value of the tumor (Hounsfield units) with that of the liver parenchyma.
Intratumoral Flow Void Diameter as a Predictor of High Intraoperative Blood Loss in Palliative Excisional Surgery for Metastatic Spinal Tumors.

Massive intraoperative blood loss (IBL) is one of the major complications in metastatic spinal tumor surgery (MSTS), and understanding the predictors of this risk is essential. This study aimed to determine the impact of the intratumoral flow void (IFV) observed on standard magnetic resonance imaging (MRI) and its association with IBL in palliative surgery for metastatic spinal tumors. This retrospective analysis included 88 palliative excisional surgeries performed at a single hospital between 2010 and 2024.

LSF is assessed using Tc macroaggregated albumin ( Tc-MAA) imaging, but this approach adds risk, complexity, and expense to the treatment planning. This study investigates the potential of Contrast-Enhanced Computed Tomography (CECT) as a non-invasive alternative for LSF estimation.

Hyalinizing clear cell carcinoma (HCCC) is a rare, low-grade epithelial tumor predominantly found in the salivary glands, with tracheal involvement being particularly uncommon. The present study details a case of primary tracheal HCCC and its clinical presentation, diagnostic challenges and the therapeutic approach used. A 34-year-old female patient presented with a 1-month history of intermittent dyspnea.

Objective: To maximize local tumor control, stabilize affected bones, and preserve or replace joints with minimal interventional burden, thereby enhancing quality of life for empowered living.
Indications: Suitable for patients with bone metastases, particularly those with severe pain and/or fractures and appropriate life expectancy.
Contraindications: In primary bone tumors, refer to the sarcoma surgery team for evaluation of wide resection.
