     Pediatric Radiology CasesPathomorphology or Pathophysiology of this disease : *

    Lipoma in the CPA are maldevelopmental masses arising from abnormal differentiation of the meningeal precursor tissue.  

     
     Pediatric Radiology CasesRadiological findings: *


    MRI 1 <- view MRI 1

    MRI 1: T1W MRI showing hyperintense mass in right CP angle cistern extending into the internal auditory canal.




    MRI 2 <- view MRI 2

    MRI 2: T2W MRI showing hyperintense mass with splaying of 7th and 8th cranial nerves.




    MRI 3 <- view MRI 3

    MRI 3: T1W post gadolinium fat suppressed image showing nonenhancing mass with fat suppression.

     Pediatric Radiology CasesCourse / Prognosis / Frequency / Other : *

    It usually does not grow over time and malignant transformation has not been reported.

    CPA Lipoma is a rare tumor with an incidence of 10% of all intracranial lipomas and less than 0.14% of all CPA tumors. It has a tendency to infiltrate with splaying of 7th and 8th cranial nerves. Surgical excision is usually avoided due to intermingled nerve fibers and adherence to neural structures via fibrous elements.

    The most common site for intracranial lipoma is interhemispheric fissure. Other sites are quadrigeminal cistern, pineal region, CPA, suprasellar cistern and sylvian fissure.
