A 38-year-old woman with recurrent metastatic cervical adenocarcinoma developed innumerable bilateral solid and cavitating pulmonary metastatic nodules. After chemotherapy with paclitaxel and carboplatin, all these nodules regressed to air filled cystic structures with imperceptible walls, pneumatoceles. Immunocompromised patients require close monitoring for development of these as they may be complicated by secondary infection, pneumothorax formation or develop into a tension pneumatocele.
