Most of the pancreatic head leptomeningeal occupying lesions are pancreatic head cancer, and some few patients are benign tumors. Pancreatic head leptomeningeal occupying lesions need to do further enhanced CT or MRI scan to determine the benignness and malignancy of the disease, as follows: 1. Pancreatic head cancer, the main clinical symptom is that due to the malignant tumors are growing relatively fast, which presses the lower part of the bile duct, thus causing obstructive jaundice, and it can be manifested as painless jaundice, clay-like stools, which need to be carried out pancreas and duodenum resection; 2. 2, benign pancreatic tumor because of slow growth, usually most do not cause obvious clinical symptoms, almost in the physical examination or abdominal ultrasound CT examination inadvertently found. When benign tumors do not cause clinical symptoms, they can be closely observed, and when they increase in size and cause pressure symptoms, surgery can be considered.
