Leptomeningeal carcinomatosis secondary to gastroesophageal adenocarcinoma: a case report and review of the literature.
BACKGROUND
Leptomeningeal carcinomatosis (LC) is a rare metastatic complication of solid tumours. It has been mainly described in association with breast cancer, lung cancer and melanoma.


METHODS
A patient presenting with progressive solid food dysphagia with documented adenocarcinoma of the lower esophagus and gastroesophageal junction is reported. One month after the initial diagnosis, the patient developed gradual onset of increasing headache and progressive decrease in the level of consciousness. Computed tomography of the head showed evidence of meningeal enhancement, and cerebrospinal fluid examination showed the presence of adenocarcinoma cells, making the diagnosis of LC. The patient died one month after LC was diagnosed.


CONCLUSIONS
LC is a poor prognostic sign in solid organ malignancies. It usually presents with headache, altered level of consciousness and focal neurological deficits. Diagnosis is established by finding malignant cells in the cerebrospinal fluid and supported by marked meningeal enhancement on computed tomography of the brain. A review of the English literature found only three reported cases of LC secondary to esophageal malignancy.


CONCLUSIONS
A case of LC complicating esophageal and gastroesophageal junction malignancy is described. A high index of suspicion and early diagnosis may influence the poor outcome of these patients.
