1- A broad spectrum of diseases can cause intracranial cysts.
The discussion includes an algorithm that describes respectively: primary non-tumoral intracranial cysts; inflammatory pseudo-cyst,
and infectious pseudo-cysts.
2- The second purpose of our study was to show the imaging findings of cystic intracranial lesions and to recognize their differential diagnosis.
We report a retrospective study that evaluates 66 cases of cystic intracranial lesions or with cystic components,
seen during the two-year period from January 2009 to February 2011.
Our patients underwent cerebral CT scanning (n=26) and/or undergo cerebral MR imaging (n=50) (diagram.1).
Diagnosis of intracranial cyst were confirmed by imaging findings and if necessary with histopathological analysis.
Imaging findings OR Procedure details
Imaging Findings: The results that were obtained (Diagram.2): Arachnoid cysts (n=17),
porencephalic cysts (n=9),
enlarged perivascular spaces or Virchow-Robin spaces (n=9),
pineal cyst (n=1),
Rathke’cleft cyst (n=3),
neuroglial cyst (n=1),
intracranial dermoid cyst (n=1),
epidermal cysts (n=4),
pseudo-inflammatory cyst associated to multiple sclerosis (n=1),
hydatid cysts (n=8),
neurocysticercosis cysts (n=2),
tuberculosis abscess (n=3),
pyogenic abcess (n=5),
Cystic intracranial benign masses are frequently observed on our daily practice.
So a careful review of topographical and morphological features presents a big help to narrow the differential diagnosis list.
