    Area of Science:

    • Pediatric Neurosurgery
    • Neuro-oncology
    • Developmental Biology

    Background:

    • Pineal region tumors are rare and can present with diverse neurological symptoms.
    • Teratomas, germ cell tumors containing multiple germ layer derivatives, are among the neoplastic entities found in the pineal region.
    • Early diagnosis and surgical management are crucial for favorable outcomes.

    Observation:

    • A 3-year-old boy presented with progressive nausea, vomiting, and altered consciousness.
    • Clinical examination revealed signs of increased intracranial pressure and focal neurological deficits.
    • Imaging studies, including CT and angiography, identified a cystic mass in the pineal region with mass effect.

    Findings:

    • Histopathological analysis confirmed a pineal teratoma, characterized by the presence of epidermal and dermal appendages, bone, cartilage, and neural tissue.
    • The tumor was completely excised via a right occipital transtentorial approach.
    • No evidence of germinoma was found on examination.

    Implications:

    • This case underscores the successful surgical resection of a complex pineal teratoma in a pediatric patient.
    • Complete tumor removal is associated with improved neurological outcomes.
    • Accurate histopathological diagnosis is essential for guiding further management and prognosis.
