 | Age: | 5 Months | |
 | Gender: | N/A | |
 | Region-Organ: | Head-Brain and brain nerves | |
 | Most likely etiology: | congenital | |
 | History: | 5 month-old infant, only slightly delayed statomotoric development since the 3rd month of life.
Clinical signs are often initially seen in adulthood due to a problem with CSF circulation (intracranial pressure signs, epileptic episodes). | |
 | Pathomorphology or Pathophysiology of this disease : | Spaces filled with fluid due to duplication or splitting of the arachnoid, (Gap formation between the arachnoid and the pia mater), congenital cause, sometimes dysplasia of the surrounding brain regions possible (i.e. temporal lobe). | |
 | Radiological findings: |
<- view MRI 1
MRI 1: Findings of a (in this case unusually large) CSF-isointense tumorous, cystic cavity, here temporally on the right side. Gyration and cortex of the brain is intact (in contrast to an infarction). Shown is a coronal slice, T2-weighted.
<- view MRI 2
MRI 2: Transversal slice, T1-weighted
<- view MRI 3
MRI 3: Coronal slice, T2-weighted after surgical, internal rerouting of the arachnoidal cyst. The brain has completely expanded, no defect is detectable.
Particularly common is the temporal localisation, but basal and in interhemispheric cisterns have also been seen.

 | Diagnosis confirmation: | Surgery / Histo | |
 | Which DD would be also possible with the radiological findings: | Infarction - (respective of the cortical surface by the arachnoidal cyst). | |
 | Course / Prognosis / Frequency / Other : | To clarify the question of a communication with the subarachnoidal space, an intrathecal injection of contrast media is necessary. Surgical indication is given by an obvious tumor and absence of communication with the subarachnoid space. | |
 | Comments of the author about the case: | Image 1 & 2: Beginning findings 8/99 Image 3: Follow up image 10/01, findings after surgery 10/00. Remission. | |
