A case of thoracolithiasis diagnosed thoracoscopically

INTRODUCTIONThoracolithiasis is quite rare with only 18 cases reported in the literature.PRESENTATION OF CASEThe 65-year-old female was referred to us for the abnormality on the chest X-ray. The serial computed tomographic (CT) scans showed a mobile calcified nodule of about 10 mm in diameter. Exploratory thoracoscopy was performed. A 15 mm pearl-like pleural stone was removed with uneventful postoperative course.DISCUSSIONThoracolithiasis is very rare, and its etiology as well as its epidemiology still remains to be unclear. Preoperative diagnosis is always difficult. However, specific radiological findings could let us recognize the probability of that lesion and avoid unnecessary major operation.CONCLUSIONThoracolithiasis should never be overlooked as a differential diagnosis in a pulmonary calcified nodule.
