[Case of pineal body tumor]

Area of Science:

• Neuro-oncology
• Radiology
• Endocrinology

Background:

• Epiphyseal tumors present diagnostic challenges, often mimicking other intracranial pathologies.
• Clinical presentation can include signs of increased intracranial pressure and hypothalamic dysfunction.

Observation:

• A male patient with an epiphyseal tumor was diagnosed using positive-contrast ventriculography.
• Treatment involved ventriculoatrial shunt and radiotherapy.
• Initial diagnostic difficulties arose due to the absence of pathognomonic signs of lamina quadrigemina lesions, leading to suspicion of craniopharyngioma.

Findings:

• Positive-contrast ventriculography proved effective for diagnosing this epiphyseal tumor.
• Disturbances in vertical optokinetic nystagmus and auditory test alterations were noted.
• These specific neurological findings are highlighted as potentially crucial for early epiphyseal tumor diagnosis.

Implications:

• Early diagnosis of epiphyseal tumors may be facilitated by evaluating vertical optokinetic nystagmus and auditory function.
• This case underscores the importance of considering epiphyseal tumors in the differential diagnosis of sellar/suprasellar masses.
• Further research into these specific diagnostic markers could improve patient outcomes for epiphyseal tumors.
