Benign Non-cystic Mediastinal Disease

Knowledge of the range of non-neoplastic and benign mediastinal and thymic lesions is indispensable due to their morphological similarity to their neoplastic counterparts. Therefore, non-neoplastic lesions should always be included in the differential diagnosis during diagnostic workup of any mediastinal mass. Clinically and radiologically, these lesions often closely mimic mediastinal malignancies and tissue diagnosis is usually necessary for definitive diagnosis. Consideration of the age of the patient, symptomatology, laboratory results, as well as the exact topography of the lesion diagnosis or even resection of the entire lesion is often is usually necessary for definitive diagnosis. Important for correct diagnosis of thymic lesions is also Consideration of the age of the patient, symptomatology, laboratory results, as well as the exact topography of the lesion are other important factors in the evaluation of mediastinal lesions. Another crucial parameter in the assessment of thymic pathology is the size and weight of the thymus in relation to an age-specific reference range.
