Introduction:
Parinaud's Syndrome is an inability to move the eyes upwards which is caused by damage to the tectal plate of midbrain. Commonest causes implicated are the Pineal tumors in children, Multiple Sclerosis in adults and stroke in elderly patients. We present a rare case of Tectal plate tuberculoma leading to Parinaud's Syndrome.
Discussion:
Parinaud's syndrome is caused by damage to the tectal plate or posterior commissure of midbrain. Our patient presented with upward gaze paresis and was diagnosed to have tuberculoma involving the midbrain region. He was managed conservatively and responded to the treatment.
Conclusion:
Tectal plate tuberculoma though a rare possibility, warrants proper diagnostic workup in order to prevent unnecessary brainstem surgery.
