Choriocarcinoma Masquerading as Lung Abscess or Lung Cancer: A Case with Atypical Imaging Findings.

Choriocarcinoma with a solitary lung lesion as the first presentation and no lesions in the uterus is clinically rare. This may lead to a delay in diagnosis due to poor awareness of the disease and the appearance of multiple metastases throughout the body. Clinicians should be more aware of choriocarcinoma with an atypical presentation to reduce misdiagnosis and missed diagnosis.
