Intrasellar arachnoid cysts.

F B Meyer, S M Carpenter, E R Laws

    Surgical Neurology

    Summary
    This summary is machine-generated.

    Transsphenoidal surgery effectively treated intrasellar arachnoid cysts, relieving visual loss and hyperprolactinemia. However, anterior pituitary dysfunction did not improve, indicating potential need for hormonal replacement post-surgery.

    Area of Science:

    • Neurosurgery
    • Endocrinology
    • Pathology

    Background:

    • Intrasellar arachnoid cysts are rare sellar lesions.
    • Symptoms can include headache, visual disturbances, and hormonal imbalances.
    • Surgical intervention is often considered for symptomatic cases.

    Purpose of the Study:

    • To analyze the outcomes of transsphenoidal surgery for intrasellar arachnoid cysts.
    • To evaluate the efficacy of cyst excision and marsupialization.
    • To discuss the pathophysiology and surgical indications for these cysts.

    Main Methods:

    • Retrospective analysis of 13 patients with pathologically confirmed intrasellar arachnoid cysts.
    • Treatment involved transsphenoidal cyst excision and marsupialization.

  • Patient symptoms and postoperative outcomes were documented.

    • Main Results:

    • Significant improvement in visual loss (7/7 patients) and hyperprolactinemia (4/4 patients) post-surgery.
    • No improvement in anterior pituitary dysfunction (2/2 patients).
    • Two additional patients required hormonal supplementation postoperatively.

    Conclusions:

    • Transsphenoidal surgery is effective for relieving mass effect symptoms like visual loss and hyperprolactinemia caused by intrasellar arachnoid cysts.
    • Surgical outcomes for anterior pituitary dysfunction are poor, suggesting potential for persistent or new hormonal deficits.
    • Indications for surgery include relieving compression of optic chiasm, pituitary stalk/gland, and excluding other sellar neoplasms.
