[Brain stone. A case report].

Area of Science:

• Neurology
• Neurosurgery
• Pathology

Background:

• Presents a rare case of an idiopathic brain stone.
• Highlights the diagnostic challenges of intracranial calcifications.

Observation:

• A 43-year-old woman presented with seizures and a calcified shadow in the right temporal lobe.
• Neuro-radiological examination revealed a dumbbell-shaped calculus (17x10 mm).
• Electroencephalography (EEG) and clinical observations were inconclusive.

Findings:

• Surgical excision of the calculus was performed.
• Histopathological examination identified it as a collection of PAS-positive spherical lamellar particles.
• The mass was a hard calculus with minimal perifocal gliosis, easily separable from brain tissue.

Implications:

• Successful surgical removal of the idiopathic brain stone led to complete seizure resolution.
• This case contributes to the understanding of rare intracranial calcifications.
• Emphasizes the importance of surgical intervention for symptomatic brain stones.
