Diagnosis based on electromagnetic navigational bronchoscopy-guided biopsied peripheral lung lesions in a 10-year-old girl: A case report

Figure 1 Bronchoscopy and computed tomography images at different stages of treatment. A: Basal segment of the lower lobe of the left lung under conventional bronchoscopy during the first hospitalization; B: Computed tomography (CT) scan showed a lesion in the outer basal segment of the lower lobe of the left lung grew bigger during the first hospitalization; C: CT scan showed a lesion in the outer basal segment of the lower lobe of the left lung grew bigger after the first hospitalization.

Figure 2 Three-dimensional reconstruction of thoracic computed tomography with the bronchial tree, tunnel path, and peripheral lung lesions location. A: Virtual bronchoscopic navigation images on LungPro indicate a bronchial route; B: Cross-sectional view; C: Coronal reconstruction view; D: Sagittal view; E: Three-dimensional view.

Figure 3 Transbronchial lung biopsy, postoperative pathological examination and computed tomography image results after treatment. A: Transbronchial lung biopsy under bronchoscopy; B: Endotracheal biopsy showing bacterial colonization, 200× magnification; C: High-resolution computed tomography (HRCT) obtained after treatment. Chest HRCT scans show the transparency of the basal segment of the left lower lobe increased, multiple lesions of unequal size, multilocular thin-walled air bag cavity can be seen. Compared with the former chest CT, some lesions are absorbed.
