Summary
Disorders of the choroid plexus are rare and challenging to diagnose. This review details imaging findings for various lesions, aiding in differential diagnosis for these central nervous system conditions.
Area of Science:
- Neuroimaging
- Neuroradiology
- Central Nervous System Pathology
Background:
- The choroid plexus, a key structure in the central nervous system, is rarely affected by disorders.
- Diagnosing these rare choroid plexus conditions can be complex.
Purpose of the Study:
- To review and illustrate the computed tomography (CT) and magnetic resonance imaging (MRI) findings of diverse lesions affecting the choroid plexus.
- To aid in the diagnostic process for choroid plexus pathologies.
Main Methods:
- Review of imaging findings (CT and MRI) associated with choroid plexus lesions.
- Categorization of lesions into neoplasms, infections, cysts, hemorrhage, congenital abnormalities, and inflammatory disorders.
Main Results:
- Imaging findings for various choroid plexus lesions including neoplasms (papilloma, leukemia, meningioma, lymphoma, metastases), infections (bacterial, fungal, viral), cysts, hemorrhage, congenital abnormalities (Sturge-Weber, Klippel-Trenaunay-Weber, vascular malformations), and inflammatory conditions (xanthogranulomas, pseudotumor, sarcoidosis, rheumatoid nodule, villous hypertrophy).
- Highlights the limited specificity of imaging patterns for definitive pathological diagnosis.
Conclusions:
- Computed tomography and magnetic resonance imaging are crucial for evaluating choroid plexus lesions.
- Recognizing the spectrum of imaging appearances is essential for diagnosing rare choroid plexus disorders, though few patterns are pathognomonic.
