Video Summary

In this video, the rare case of a pancreatic schwannoma diagnosed preoperatively is discussed. The role of contrast-enhanced US (ultrasound) and US elastography is explored. The video explains that endoscopic ultrasound fine needle aspiration biopsy is the preferred method for evaluating focal pancreatic masses. Multiparametric US is used for real-time guidance during the biopsy, combining grayscale imaging, color Doppler, US elastography, and contrast-enhanced US. The use of US elastography allows for the visualization of tissue strain and can be used for quantification. Contrast-enhanced US is used to visualize non-necrotic areas and major vessels. The case of a 54-year-old patient with an enlarged retroperitoneal lymph node is presented. The diagnosis of pancreatic schwannoma is confirmed through US-guided fine needle biopsy and pathology examination. Although the tumor is benign, due to its size and the potential for malignancy, the patient is referred for surgical excision. The video emphasizes that pathology diagnosis is crucial in these rare pancreatic tumors to determine the risk of malignancy, and decisions regarding patient management should be made in a multidisciplinary tumor board. No credits are mentioned in the video.
