BACKGROUND Epidural hematoma usually stems from trauma, yet it may occur fr
om other etiologies, including neoplasms. We present a case of small cell l
ung carcinoma with focal hemorrhagic central nervous system metastasis prod
ucing an epidural hematoma, and review the associated literature.
CLINICAL PRESENTATION A 67-year-old man was undergoing chemotherapy for sma
ll cell carcinoma of the lung, Acute neurologic deterioration resulted from
a large parietal epidural hematoma of non-traumatic origin.
INTERVENTION The clot was evacuated via craniotomy with marked improvement
in his clinical state. Metastatic tumor was present in the scalp, muscle, b
one, and dura. No gross brain invasion was apparent.
CONCLUSIONS This case illustrates the wisdom of including metastatic diseas
e in the differential diagnosis of intracranial hemorrhage. Even epidural h
ematoma may result from metastatic cancer. The prevalence of lung carcinoma
and the aging of the population may produce an increased appearance of thi
s phenomenon. Appropriate evaluation and rapid intervention will aid the pa
tient in both the acute and long-term phases, and should improve the qualit
y of survival. (C) 1999 by Elsevier Science Inc.
