Abstract: Objective To summarize and analyze the clinical and imaging features of pulmonary nodular lymphoid hyperplasia(PNLH)and its pathological features.Methods The clinical and imaging features of PNLH in 9 patients were analyzed retrospec-tively.Results Of the 9 patients with PNLH,5 were found incidentally while other 4 presented with chest symptoms.Laboratory tests showed no specificity,and the lesions were located under the pleura with adjacent pleural indentation.Most lesions were solid with spiculation sign or spiculate protuberance.Hypodense area and vocule were visible within some lesions.Enhanced scan showed the lesion with marked enhancement,however most did not had lymph node enlargement and pleural effusion.Conclusion The clin-ical manifestations of PNLH are non-specific,and the imaging characteristics overlap with those of malignant lung tumors.Thus the diagnosis of PNLH relies on the pathological examination.
