Figure 4 (a) CT chest with subcarinal and hilar lymphadenopathy of a 70-year-old male patient. (b) PET/CT positive uptake in subcarinal and hilar region. (c) A 22 G needle used for conventional sampling. (d) Preparation of thin smear over slides. Despite positive FDG-PET uptake of mediastinal lymph nodes and sufficient sampling (objective sufficiency −12 prepared slides) (pathological sufficiency with demonstrated few cellularity and lymphocytes. The result was negative conventional sampling). Patient refused resampling with EBUS. CT, computed tomography; EBUS, endobronchial ultrasonography; PET, positron emission tomography.
