Sporadic Hemangioblastoma in the Pituitary Stalk: A Case Report and Review of the Literature.

Lee GI, Kim JM, Choi KS, Kim CH - J Korean Neurosurg Soc (2015)

Bottom Line: Most pituitary stalk hemangioblastomas reported in the literature were associated with von Hippel-Lindau (VHL) disease.Here, we report only the 3rd case of sporadic pituitary stalk hemangioblastoma diagnosed in a 60-year-old woman.Despite the danger of potential complications due to excessive vascularity or proximity to important neural structures, the tumor in our case was successfully removed while preserving pituitary function.

ABSTRACT
Hemangioblastomas in the pituitary stalk are especially rare. Most pituitary stalk hemangioblastomas reported in the literature were associated with von Hippel-Lindau (VHL) disease. Here, we report only the 3rd case of sporadic pituitary stalk hemangioblastoma diagnosed in a 60-year-old woman. Despite the danger of potential complications due to excessive vascularity or proximity to important neural structures, the tumor in our case was successfully removed while preserving pituitary function. In this case, complete surgical excision was shown to be an effective treatment option for symptomatic pituitary stalk hemangioblastoma, and we suggest careful evaluation of any highly enhancing mass with a signal void in the pituitary stalk preoperatively, even if no VHL disease is evident.

No MeSH data available.

The sagittal (A) and coronal (B) brain magnetic resonance images with contrast which obtained 6 months after complete removal of the tumor demonstrate an intact pituitary stalk and no residual tumor.

Figure 4: The sagittal (A) and coronal (B) brain magnetic resonance images with contrast which obtained 6 months after complete removal of the tumor demonstrate an intact pituitary stalk and no residual tumor.

Mentions: Postoperatively, the patient experienced considerable improvement of her symptoms and the postoperative period was uneventful except for occurrence of transient diabetes insipidus which was successfully managed with fluid control and hormonal replacement therapy. During the follow up period, a manifestation of the VHL complex was investigated and screening for other HBLs was performed, but there were no remarkable findings. Cranial MR images, obtained 6 months after surgery, demonstrated an intact pituitary stalk and no residual tumor (Fig. 4). Up to the present, 1 year after surgery, she lives well without neurological deficits or pituitary dysfunction.
