Figure 1From: Familial summer-type hypersensitivity pneumonitis in Japan: two case reports and review of the literatureRadiological and pathological assessment for two patients. (wife; A, B, and C): Chest x-ray on the day of admission shows mild infiltrates predominantly in the middle to lower lung fields with multiple scattered nodular lesions (Panel A). Thoracic CT (computed tomography) taken on the same day confirms that these lesions correspond to ground-glass opacities and abundant centrilobular nodules, predominantly located in the bilateral lower lobes (Panel B). Specimens obtained from transbronchial lung biopsy (TBLB) demonstrate organization within the peribronchial area with alveolitis, suggesting transbronchial spread (Panel C). (husband; D, E, and F): Chest x-ray (Panel D) and thoracic CT (Panel E) show ground glass opacities in the upper lungs on both sides. The specimens obtained from TBLB at his local hospital reveals organizing tissue within the peribronchial area with alveolitis, suggesting transbronchial spread (Panel F).Back to article page
