Easy bruisability and terminal coma in a "normal" 5-month-old infant.

The patient was a 5-month-old white male admitted in coma via transferral 
from another hospital. Clinical discussion argues that this child had acquired 
coagulopathy due to vitamin K deficiency and that this was secondary 
to the fat malabsorption that occurs in cystic fibrosis. The left 
third nerve palsy and contralateral hemiparesis in a patient with rapid 
neurologic deterioration suggest a mass lesion in the left cerebral hemisphere 
with uncal herniation. Pathologic discussion also suggests intracranial hemorrhage, massive on 
left, accompanied by cystic fibrosis with severe pancreatic lesions and bleeding 
disorder, probably due to vitamin K deficiency.
