[Multiple cavitary pulmonary metastases from ovarian cancer: a case report]

Cavitation in pulmonary metastases is thought to be uncommon. To date, few cases of pulmonary metastases originating from ovarian cancer and showing cavitation have been reported. We report a patient with multiple cavitation in pulmonary metastases from ovarian mucinous cystadenocarcinoma. A 28-year-old woman was admitted to our hospital presenting with cough and fever. The patient had undergone right ovariectomy for ovarian mucinous cystadenocarcinoma at the age of 23 years. Her chest radiograph on admission showed multiple cavities associated with infiltration in both lungs. Histological sections obtained by transbronchial lung biopsy revealed mucus-secreting adenocarcinoma, and a diagnosis of metastatic lung cancer from the ovary was made. Computed tomographic (CT) scans of the chest demonstrated various findings, including multiple thick-walled cavities, thin-walled cavities, air-space consolidations, ground glass opacities, and centrilobular nodular shadows formed by aspiration of the mucinous secretions. It is important to recognize that cavitation can occur in pulmonary metastases from ovarian cancer.
