Neurocysticercosis (NCC) is the most common parasitic infestation of the central nervous system. Most cases of NCC are to related and/or associated with inflammation within the cerebral parenchyma. A 71-year-old woman presented with a 4-year history of visual disturbance. This symptom had become aggravated 4 weeks earlier. Her visual acuity gradually decreased and superior hemianopsia was noted. Magnetic resonance imaging (MRI) revealed an enhanced and thickened pituitary stalk accompanying a suspicious mass. The provisional diagnoses were lymphoma, glioma, or other inflammatory conditions. Laboratory studies, including blood and hormonal studies, showed normal findings. Surgical resection was performed. In the pathological examination, degenerated parasitic wall structure was seen and its contents were composed of completely degenerated focal globular structures suggesting the scolex of cysticercus. We report an unusual case of NCC involving the pituitary stalk which was presented with a juxtasellar tumor. The possible underlying mechanisms are discussed with a review of pertinent literature.
神经囊尾蚴病（NCC）是中枢神经系统最常见的寄生虫感染。大多数NCC病例与脑实质内的炎症相关和/或有关联。一名71岁女性有4年视觉障碍病史。该症状在4周前加重。她的视力逐渐下降，出现上象限偏盲。磁共振成像（MRI）显示垂体柄增粗且强化，伴有可疑肿块。初步诊断为淋巴瘤、胶质瘤或其他炎症性疾病。包括血液和激素检查在内的实验室检查结果均正常。进行了手术切除。病理检查发现退化的寄生虫壁结构，其内容物由完全退化的局灶性球状结构组成，提示为囊尾蚴的头节。我们报告一例罕见的累及垂体柄的NCC病例，该病例表现为鞍旁肿瘤。结合相关文献对可能的潜在机制进行了讨论。
