A 75-year-old man was admitted to our hospital because of severe dyspnea and pollakiuria in October 2001. We diagnosed his illness as carcinomatous pericarditis caused by the recurrence of primary lung cancer and prostatic hypertrophy. He had undergone surgery for gastric cancer in 1986, and for lung cancer in 1996. Furthermore, he had been treated for hepatocellular carcinoma in 1997. He finally died in February 2002 of respiratory failure due to the carcinomatous lymphangitis that followed the lung cancer. After autopsy, a microscopic view of the prostate revealed that he had prostatic carcinoma. Such a case is rare.

A 60-year-old male was diagnosed with T3, N3, M1b epidermal growth factor receptor (EGFR) mutant lung adenocarcinoma. Five months later he developed significant headaches, weakness and numbness of the left leg, and unsteadiness of gait. Magnetic resonance imaging (MRI) brain demonstrated subtle gyral enhancement indicative of early leptomeningeal infiltration. He was commenced on second-line erlotinib which improved his lower limb symptoms. Three months later he developed increased urinary frequency and redeveloped leg symptoms. MRI brain showed improvement in the gyral enhancement. Four weeks later, the patient developed new onset confusion and decrease in mobility. Examination of the cerebrospinal fluid (CSF) demonstrated leptomeningeal carcinomatosis. This case demonstrates radiological and clinical response of leptomeningeal disease to erlotinib in EGFR mutant lung cancer with subsequent clinical relapse despite continued radiological resolution of leptomeningeal disease. This suggests that CSF examination should be considered when monitoring leptomeningeal disease response following treatment as the disease can be undetectable on repeat radiological imaging.
