title: Invasive growth patterns of juvenile nasopharyngeal angiofibroma: radiological imaging and clinical implications.
abstract: Juvenile nasopharyngeal angiofibroma is a benign lesion with locally aggressive nature. Knowledge of its typical growth patterns is crucial for precise preoperative staging and adequate preoperative patient counseling. This pictorial essay focuses on characteristic radiological features and paths of invasive growth of this rare tumor. Also, the impact of accurate preoperative evaluation of tumor extensions on surgical planning and results of treatment are discussed.
