Diagnosis With Brief Discussion

Diagnosis
Pleural Metastasis from Esophageal cancer
Radiologic Findings
Chest radiograph shows an about 8 x 7 cm-sized pleural mass in the right lateral costophrenic sulcus. Several surgical clips in right infrahilar area suggest previous operation. Long tubular air-densities overlap with the right side of mediastinal structure. Right pneumothorax is a result of PCNB (percutaneous needle biopsy). CT scans show multiple pleural masses and small amount of pleural effusion. In the posteromedial mediastinum, collapsed stomach is seen. Ivor Lewis operation (lower esophagectomy with esophagogastrostomy) had been perfomed in this patient due to esophageal cancer 6 months before. PCNB was done for pleural mass. Pathological diagnosis was metastatic squamous cell carcinoma histologically identical to esophageal carcinoma.
Brief Review
Carcinomatous metastases to the pleura can originate from almost any organ with the lung as the most frequent primary site, followed by breast, pancreas, stomach, ovary, and etc. Metastasis to the pleura from esophageal cancer is very rare. Distant metastases from esophageal cancer were most commonly diagnosed in abdominal lymph nodes (45%), followed by liver (35%), lung (20%), cervical / supraclavicular lymph nodes (18%), bone (9%), adrenal (5%), peritoneum (2%), brain (2%) and stomach, pancreas, pleura, skin/ body wall, pericardium, and spleen (1% each).
Metastasis, malignant lymphoma or malignant mesothelioma should be considered in the differential diagnosis of multiple pleural masses and effusion. In this case, clue of diagnosis is surgical clips and collapsed stomach in the posterior mediastinum suggesting previous esophageal operation.
