Third ventricle choroid plexus papilloma with head tremors

Area of Science:

• Neuro-oncology
• Pediatric Neurosurgery
• Neuropathology

Background:

• Choroid plexus papillomas (CPPs) are rare tumors typically arising in the fourth or lateral ventricles.
• Third ventricular CPPs are exceptionally uncommon, posing diagnostic challenges.
• Clinical presentation often includes signs of increased intracranial pressure.

Purpose of the Study:

• To report a rare case of a third ventricular choroid plexus papilloma in a pediatric patient.
• To highlight an unusual presenting symptom of this rare tumor.
• To contribute to the understanding of CPPs in the third ventricle.

Main Methods:

• Case report of a two-year-old male.
• Clinical presentation analysis including neurological examination findings.
• Review of relevant literature on third ventricular choroid plexus papillomas.

Main Results:

• The patient presented with symptoms of raised intracranial pressure, meningismus, gait ataxia, and abnormal head tremors.
• Abnormal head tremor was identified as an extremely uncommon presenting feature for a third ventricular choroid plexus papilloma.
• Diagnostic imaging confirmed the presence of a tumor in the third ventricle.

Conclusions:

• Third ventricular choroid plexus papillomas, though rare, can present with atypical neurological signs.
• Abnormal head tremor should be considered in the differential diagnosis of pediatric patients with suspected intracranial masses.
• This case underscores the importance of comprehensive evaluation in rare pediatric neurological conditions.
