[Evaluation of CT and MRI in diagnosis of intranasal encephalomeningocele].
OBJECTIVE
To evaluate the values of CT and MRI in diagnosing intranasal encephalomeningocele.


METHODS
The CT and MRI features of 7 cases confirmed by operation and pathology were retrospectively analyzed.


RESULTS
CT and MRI demonstrated that all cases were encephalomeningocele and 1 case was accompanied with hydrocephalus. MRI demonstrated that the herniation in nasal cavity were glial tissue and meninges, the signals are abnormal cerebrospinal fluid signal and it was attached to intracranial subarachnoid cavity.


CONCLUSIONS
CT and MRI could diagnose encephalomeningocele correctly. CT could clearly manifest the size and location of the defect of cranial base bone, and the location of hernia. MRI was more advantageous than CT in displaying the contents in hernia, and the relationship between hernia and cranial base. Coronal and axial imaging planes with MR T1- and T2-weighted sequences are required to demonstrate intracerebral connection.
