    Apical caps, often seen with aging, result from scarring. Various conditions, including tumors, inflammation, and trauma, can cause unilateral or bilateral apical caps.

    Area of Science:

    • Radiology
    • Thoracic Imaging
    • Pulmonary Medicine

    Background:

    • Apical caps are common findings in aging patients, typically due to subpleural scarring.
    • Unilateral asymmetric apical density can indicate Pancoast (superior sulcus) tumors.
    • Various thoracic pathologies can manifest as apical caps.

    Purpose of the Study:

    • To comprehensively review the differential diagnoses for unilateral or bilateral apical caps.
    • To categorize the diverse etiologies of apical caps beyond simple age-related scarring.

    Main Methods:

    • Review of medical literature and imaging findings related to apical caps.
    • Categorization of causes based on pathological processes: inflammatory, neoplastic, traumatic, vascular, and miscellaneous.

    Main Results:

    • Apical caps can stem from inflammatory conditions like tuberculosis and extrapleural abscesses.
    • Neoplastic causes include lymphoma, superior sulcus bronchogenic carcinoma, and metastases.
    • Traumatic and vascular etiologies encompass aortic rupture, rib fractures, and arteriovenous fistulas.

    Conclusions:

    • Apical caps represent a spectrum of conditions, necessitating a thorough differential diagnosis.
    • Recognition of diverse causes is crucial for accurate patient management and treatment planning.
