Abstract
A 7-year-old boy was admitted to the emergency department after a closed head injury.
Physical examination revealed no neurological disturbances or scalp laceration. Computed
tomography revealed depressed skull fracture on the right occipital bone with multiple
fracture lines over the right transverse sinus. Magnetic resonance imaging revealed
right transverse sinus thrombosis, and magnetic resonance venography identified total
occlusion of the right transverse sinus due to bone compression. Despite the presence
of venous sinus injury secondary to a depressed skull fracture, surgery was not indicated
for this patient. Despite persistence of a right occipital depression fracture identified
during a three-dimensional cranial computed tomography performed in the third month
following the trauma, the patient's magnetic resonance venography showed spontaneous
recanalization of the right transverse sinus. It was demonstrated that venous sinus
occlusion secondary to a depressed fracture could heal spontaneously and independently
of bone pathology. With such characteristics, this report represents an extremely
rare case.
