Background: Bronchiolar adenoma (BA) is frequently misdiagnosed as peripheral lung cancer (PLC) because it resembles PLC. Computed tomography (CT) examination is an effective tool for detecting and diagnosing lung diseases. To date, there has been no comprehensive study on the differential diagnosis of BAs and PLCs using thin-section computed tomography (TSCT) based on a large sample, and the efficiency of CT in diagnosing BAs has not been verified.

Department of Radiology, The First People's Hospital of Yunnan Province, Kunming 650032, Yunnan,  China; The Affiliated Hospital of Kunming University of Science and Technology, Kunming 650032, Yunnan, China. Electronic address:

Rationale And Objectives: Evaluating the capability of CT nomograms and CT-based radiomics nomograms to differentiate between Bronchiolar Adenoma (BA) and Early-stage Lung Adenocarcinoma (LUAD).

Materials And Methods: In this retrospective study; we analyzed data from 226 patients who were treated at our institution and pathologically confirmed to have either BA or Early-stage LUAD. Patients were randomly divided into a training cohort (n=158) and a testing cohort (n=68).

[Common issues and solutions in intraoperative frozen pathological diagnosis of small pulmonary nodules].

Zhonghua Bing Li Xue Za Zhi

August 2024

Department of Pathology, Shanghai Chest Hospital, Shanghai Jiaotong University Medical School, Shanghai 200030, China.

Article Synopsis
  • The advancement of chest CT screening has led to the surgical removal of more small lung nodules instead of large tumors.
  • Intraoperative frozen diagnosis of these small nodules presents challenges, particularly in distinguishing various types of adenocarcinomas and other conditions.
  • This study highlights common diagnostic issues faced during surgery, aiming to improve accuracy in diagnosing small pulmonary nodules and reduce misdiagnosis.
