Interhemispheric lipoma: Interval development of an associated cyst
Radiology Case Reports
|June 17, 2016
Summary
An 11-year-old developed a new interhemispheric cyst alongside an intracranial lipoma over 10 years. This is unusual, as such cysts typically occur with corpus callosum abnormalities, which this patient lacked.
Area of Science:
- Neuroimaging
- Pediatric Neurology
- Developmental Neuroscience
Background:
- Intracranial lipomas are congenital tumors often associated with corpus callosum dysgenesis.
- Interhemispheric cysts are also frequently linked to developmental abnormalities of the corpus callosum.
Observation:
- An 11-year-old patient presented with incidental findings on CT imaging.
- Over a 10-year period, a new interhemispheric cyst developed in association with a known intracranial lipoma.
Findings:
- The patient exhibited an intracranial lipoma but possessed a normal corpus callosum.
- The incidental development of an interhemispheric cyst in this context is an uncommon presentation.
Implications:
- This case challenges the typical association between interhemispheric cysts, intracranial lipomas, and corpus callosum dysgenesis.
- Further research may elucidate alternative developmental pathways for these central nervous system malformations.
