    neoplastic  

     
     Pediatric Radiology CasesHistory:

    An almost 17 year-old female patient complains about reoccurring, strong pain in the right side of the face, whereas these mostly are manifested in the forehead as well as the maxillary region; in the corresponding trigeminal nerve branches. The first manifestation of the illness showed itself about 4 years before the examination. Of late, the pain has increased in duration and intensity. Medicinal treatments are only difficult to treat. The patient feels a strong sense of suffering and an inhibition of her quality of life. Clinical-neurological examination showed no relevant causalities as of yet.  

     
     Pediatric Radiology CasesPathomorphology or Pathophysiology of this disease :

    The neurovascular compression is a main cause of chronic trigeminal neuralgia. Cause for this is either small vascular intertwining or - as in this case - vessels with large caliber. Only with high-resolution MRI-sequences could causes be shown. It is assumed that a chronic pulsating irritation causes the neuralgias.  

     
     Pediatric Radiology CasesRadiological findings:


    The examination showed no tumorous or inflammatory changes intracranially and in the facial skull. Noticeable was, however, a difference of course of the superior cerebellar artery (SCA) on both sides, where on the right side the certain structural contact of the vessel to the entrance in the skull of the 5th cranial nerve on the lateral pons was able to be presented. In comparing both sides, the trigeminal nerve was obviously of larger caliber on the right side.



    MRI 1 <- view MRI 1

    MRI 1: The SCA leaving the basilar artery.





    MRI 2 <- view MRI 2

    MRI 2: Parapontine course of the SCA





    MRI 3 <- view MRI 3

    MRI 3: Neurovascular compression of the right trigeminal root through the SCA





    MRI 4 <- view MRI 4

    MRI 4: Region of contact of the SCA/trigeminal nerve (purposely overly contrasted)





    MRI 5 <- view MRI 5

    MRI 5: Trigeminal nerve on the right side is thicker in comparing both sides.





    MRI 6 <- view MRI 6

    MRI 6: No pathological enhancement of the thickened trigeminal nerve of the right side. The vessels that are seen near the right trigeminal nerve are not the SCA in this image.

    Other  

     
     Pediatric Radiology CasesWhich DD would be also possible with the radiological findings:

    The thickening of the right trigeminal nerve could also be a result of an infection or tumorous process. The missing enhancement (T1-W) makes this etiology unlikely. T2-weighted images show no edema (no difference of signal of both sides).

    Clinically, one should remember in children that such suffering could also be caused by fibrotic dysplasia in the region of the skull base.  

     
     Pediatric Radiology CasesCourse / Prognosis / Frequency / Other :

    Since medication did not lessen the symptoms, a surgical decompression can be tried (Jannetta's Technique).

    It remains hypothetical whether a thickening of the right trigeminal nerve is caused by vascular irritation. A surrounding fibrosis, a post-inflammatory state or a hypertrophy as a result of chronic alteration is conceivable -- I would welcome a discussion of this topic.

    The patient has not yet decided on a surgical treatment.  

     
     Pediatric Radiology CasesComments of the author about the case:

    Of course, 3-D reformations of the imaging material are possible (i.e. sagittal MPR). For a better overview, I have limited myself to select serial images.
