Role of Ultrasonography in the Diagnosis of Chronic Appendicitis: An Observational Study of 400 Cases

Chronic appendicitis has often been misdiagnosed due to atypical symptoms at the time of presentation. Radiological investigations are used in the evaluation of patients with a high degree of clinical suspicion. This article has demonstrated the superiority of ultrasonography over CT scan for imaging of chronic appendicitis due to its advantages such as similar efficacy rates, higher spatial resolution in identifying features of chronic appendicitis, lack of ionizing radiation, cost-effectiveness, and easy availability. However, a definitive diagnosis is achieved by demonstrating evidence of chronic inflammation in the appendectomy specimen at histopathology.
