A case report of meningeal carcinomatosis presenting as rapidly progressive dementia: cytological diagnosis with ancillary immunohistochemistry of cerebrobrospinal fluid cells.

Puntos clave

• To highlight the role of cerebrospinal fluid analysis in diagnosing meningeal carcinomatosis presenting with dementia.
• Case report involving cytological examination of cerebrospinal fluid (CSF) cells.
• Utilization of immunohistochemistry alongside CSF cytology to achieve diagnosis.
• Evaluation of neuroimaging results to rule out primary tumors.
• Rapidly progressive dementia was identified as a prominent symptom of meningeal carcinomatosis.
• Cytological diagnosis was confirmed using CSF cells with immunohistochemistry techniques.
• Neuroimaging yielded nonspecific findings, underscoring the importance of CSF analysis.
