This document summarizes several case studies examined by CT imaging. The first case discusses a 62-year-old male smoker found to have lung cancer with metastases to the brain and adrenal gland. A second case involves a 13-year-old female with acute appendicitis in an atypical retrocolic and pararenal location. A third case is about a 22-year-old female with back pain and imaging findings suggestive of a compression fracture or possible metastases. The document then briefly mentions two additional cases of sigmoid cancer and ankylosing spondylitis detected on CT scans.
