Our objective was to diagnosed these tumors by CT (Computerized tomography) & MRI (Magnetic Resonance Imaging). Materials and Method: The study was conducted between August- 2002 to December-2003 in radiology department of Shaukat Khanum Memorial Cancer Hospital and Research Centre (SKMCH & RC), which is a tertiary care center for cancer patients. The patients included in this study were diagnosed cases of non CNS PNET, who had been referred for staging work up and treatment. The biopsy was done either in the radiology department and later processed by pathology department of this hospital or the pathologists reviewed slides of biopsy done in other hospitals. The diagnosis was based on characteristic histology of the tumor & on presence of a positive MIC2 antibody. Study Design: Case-series Results: In concordance to previous studies, PNET was found more in males than females (55% vs. 45% respectively). Maximum no of patients belonged to 10-20 years of age group (47.6%). As for the radiological features like presence of calcification, adenopathy and pleural effusions.
