    Abstract:
    OBJECTIVE: In children with giant cystic solid craniopharyngioma (CP), the Ommaya reservoir was implanted in the CP cavity, and the cystic fluid was continuously drained for 5 days before the tumor resection. METHODS: An 11-year-old male patient was admitted to the hospital due to vision loss for 1 year, intermittent headache, vomiting for 6 months, and frequent urination for 2 months. Besides, magnetic resonance imaging of the head showed cystic solid lesions in the sellar region, suprasellar, and bilateral frontal lobes, with a size of 96.0×82.6×76.0 mm. Before the surgical resection, an Ommaya reservoir was implanted within the tumor cavity. The drainage was continued for 5 days and was 39 to 50 mL (43.80 ± 4.67 mL). Following the tumor shrank, a craniotomy was performed. RESULTS: Following surgical treatment, the CP was entirely removed. The child subsequently developed hypothyroidism and hypocortisolism, for which hormone replacement therapy was administered. No tumor recurrence was observed after 3 years of follow-up. CONCLUSION: The treatment of giant cystic solid CP in children is challenging. Preoperative implantation of the Ommaya reservoir, continuous drainage of cystic fluid, shrinkage of the tumor, and reduction of tumor tension are beneficial for tumor resection.
