Summary
Unusual meningeal tumors with histiocytic appearance were observed. Imaging and cerebrospinal fluid analysis initially misdiagnosed these as meningoencephalitis, highlighting diagnostic challenges.
Area of Science:
- Neuropathology
- Neuroimaging
- Cytopathology
Background:
- Meningeal tumors can present with diverse histological features.
- Accurate diagnosis is crucial for appropriate patient management.
Observation:
- Two cases of unusual pleomorphic meningeal tumors with histiocytic morphology are presented.
- Computed tomography (CT) and magnetic resonance imaging (MRI) showed no parenchymal or meningeal lesions.
- Cerebrospinal fluid (CSF) cytology revealed lymphocytic reaction but no tumor cells.
Findings:
- Histological and immunohistological analysis identified tumor cells with histiocytic features.
- Diagnostic challenges arose due to negative imaging and CSF cytology findings.
- One patient exhibited psychiatric symptoms, complicating the clinical presentation.
Implications:
- This case series underscores the importance of considering rare meningeal tumors despite non-specific initial findings.
- Advanced imaging and comprehensive diagnostic approaches are essential for accurate diagnosis.
- Understanding the histogenesis of these tumors may improve diagnostic strategies and patient outcomes.
