Symptomatic parasellar granular cell tumors.

D H Becker, C B Wilson

    Neurosurgery
    |February 1, 1981
    PubMed
    Summary
    This summary is machine-generated.

    Parasellar granular cell tumors present with visual loss and hormonal issues. Imaging can differentiate them from other suprasellar lesions, and surgery focuses on decompression, not total removal.

    Area of Science:

    • Neurology
    • Neurosurgery
    • Endocrinology

    Background:

    • Parasellar granular cell tumors (pituicytoma, myoblastoma, choristoma) are rare neoplasms.
    • Symptomatic presentations include visual loss, dementia, and adenohypophyseal insufficiency.

    Observation:

    • Computed tomographic (CT) scans reveal high-density, sharply demarcated suprasellar lesions with significant contrast enhancement.
    • Angiography may show a suprasellar blush, and lack of calcification aids in differentiating these tumors from craniopharyngioma, pituitary adenoma, and optic glioma.
    • Intraoperatively, these tumors are noted to be tough, non-suckable, and vascular.

    Findings:

    • Data from six cases and seven previously reported long-term survivors do not support the use of postoperative radiation therapy.

  • Surgical intervention should prioritize suprasellar decompression when complete excision poses significant risk.

    • Implications:

    • Accurate preoperative diagnosis using imaging modalities like CT is crucial for appropriate surgical planning.
    • Conservative surgical management focusing on decompression may be the optimal strategy for parasellar granular cell tumors to minimize morbidity.
