    Pectus excavatum deformities can mimic hilar and mediastinal masses on chest X-rays. Computed tomography effectively ruled out these masses, identifying heart and great vessel compression as the cause.

    Area of Science:

    • Cardiovascular Imaging
    • Thoracic Surgery
    • Diagnostic Radiology

    Background:

    • Pectus excavatum is a congenital chest wall deformity.
    • Radiographic findings can be misleading in pectus excavatum.
    • Hilar and mediastinal masses are significant diagnostic concerns.

    Observation:

    • Three patients with pectus excavatum presented with radiographic findings suggestive of hilar and mediastinal masses.
    • Initial radiographic assessment indicated potential masses in the chest.

    Findings:

    • Computed tomography (CT) of the chest provided crucial diagnostic information.
    • CT imaging successfully excluded the presence of actual hilar and mediastinal masses.
    • The observed findings were attributed to compression of the heart and great vessels by the pectus deformity.

    Implications:

    • CT imaging is essential for accurate diagnosis in pectus excavatum patients with atypical radiographic findings.
    • Misinterpretation of radiographic findings can be avoided with advanced imaging techniques.
    • Understanding the mechanics of pectus deformity is key to interpreting chest imaging accurately.
