The Editor,

As per practice guidelines of the American Society of Anesthesiologists (ASA), chest X-rays are recommended in patients with a history of smoking, recent respiratory tract infection, chronic obstructive pulmonary disease, and heart disease.[1] Health and Care Excellence guidelines also recommend that chest X-ray should not be done routinely in elective cases.[2]

A 41-year-old female, ASA physical status I was scheduled for surgery of fibroadenoma left breast. As a part of routine preoperative evaluation protocol, a chest X-ray was done which showed a large opacity obscuring the right hilum, suggestive of mediastinal widening with normal lung fields [Figure 1]. There were no symptoms suggestive of compression. The patient was referred back to surgeons for further evaluation. Computerized tomography (CT) chest reported a 5 cm × 3.5 cm mass with smooth lobular margins in anterior mediastinum closely abutting the ascending thoracic aorta, superior vena cava, and right atrium. CT-guided fine-needle aspiration cytology showed lymphoid cells admixed with occasional cluster of epithelial cells, suggestive of thymoma. A surgical plan of operating simultaneously for both thymoma and fibroadenoma breast was made. The patient underwent video-assisted thoracoscopic surgical removal of thymoma using one lung ventilation (35 Fr left-sided double-lumen tube), followed by excision of fibroadenoma. As per Masaoka staging system, the tumor was Grade I with good prognosis.[3] The patient was extubated and postoperative course was uneventful.

Routine preoperative screening of chest X-ray is not indicated according to international guidelines.[1],[2] Exposure to radiation, economic cost, and low incidence of clinically significant findings leading to change in anesthetic management are the reasons cited for this.[2] In India, due to high prevalence of tuberculosis, chest X-ray is generally done by surgeons and anesthesiologists as part of preoperative screening. In the present case, chest X-ray revealed an incidental finding of a large thymoma which was totally asymptomatic. Almost 30%–50% of all patients with thymoma are asymptomatic and the mass is an incidental finding on chest X-ray or CT.[4] If undetected, the tumor may increase in size and cause pressure symptoms such as superior vena cava syndrome, dysphagia, cough, chest pain, and myasthenia gravis. Once detected, thymomas must be removed surgically.[5] Hence, incidental finding was a blessing in disguise for this middle-aged woman as the tumor was still in stage 1 with good prognosis. Therefore, it is suggested that a preoperative chest X-ray examination is a useful tool during preoperative evaluation, and the international guidelines should have a relook in the light of this finding, rather than be stringently enforced.
