Chilaiditi’s Sign in a Silicosis Patient

Abstract

Chilaiditi’s sign is a rare radiological phenomenon where the transverse colon interposes between the liver and the right hemidiaphragm. Described in 1910, this is typically asymptomatic but can mimic conditions like pneumoperitoneum. Diagnosis is made through imaging, with CT being the gold standard. While asymptomatic cases require no treatment, symptomatic cases may need conservative care or, rarely, surgery. This communication describes incidental findings of Chilaiditi’s sign on a chest x-ray in a patient having a prolonged history of occupational exposure to silica dust. The diagnosis was further confirmed by the CT scan examination. The importance of this phenomenon and awareness of this finding is also stressed among clinicians in their routine practice.
