  Medical Imaging, CT Scan Diagnosis, Radiology Interpretation, Emergency Diagnosis, and Surgical Planning Introduction Imagine a healthy 28-year-old man who notices a painless lump in the middle of his neck while shaving. It has been present for months. It slowly enlarges but causes little discomfort. He assumes it is a swollen lymph node and ignores it. Several weeks later, after an upper respiratory infection, the lump suddenly becomes painful, red, and swollen. Concerned, he visits the emergency department. A contrast-enhanced CT scan reveals a well-defined cystic lesion immediately anterior to the hyoid bone. For an experienced radiologist, this location immediately narrows the diagnosis. The lesion is not simply another neck cyst. It represents one of the most common congenital neck abnormalities encountered in both pediatric and adult radiology: Thyroglossal Duct Cyst (TGDC). Although TGDC is benign in the overwhelming majority of patients, delayed diagnosis may result in r...

GIANT CELL TUMOR OF THE PATELLA: The Complete Imaging Guide from X-ray to MRI, CT, AI Diagnosis and Modern Treatment Introduction Persistent anterior knee pain is among the most common musculoskeletal complaints encountered in orthopedic clinics and radiology departments. In the majority of patients, the underlying diagnosis involves relatively benign conditions such as patellofemoral pain syndrome, chondromalacia patellae, tendinopathy, or early osteoarthritis. Because these disorders are exceedingly common, clinicians may initially attribute chronic anterior knee pain to overuse or degenerative disease. However, every radiologist eventually encounters the uncommon patient whose symptoms are caused not by a mechanical disorder but by an underlying bone tumor. Among primary tumors involving the patella, Giant Cell Tumor (GCT) deserves special attention because it represents the most frequent primary neoplasm of the patella despite the overall rarity of patellar tumors. The les...
