Therapeutic strategies for managing hemorrhagic moyamoya disease (MMD) remain controversial. In this study, we investigated the optimal therapy for hemorrhagic MMD. ⋯ Surgical revascularization, especially a direct bypass regimen, may be the optimal strategy for treating hemorrhagic MMD.

Review Case Reports
A Rare Case of Malignant Craniopharyngioma Reactive to Adjunctive Stereotactic Radiotherapy and Chemotherapy: Case Report and Literature Review.
Malignant craniopharyngioma or anaplastic craniopharyngioma was first reported in 1987 by Akachi and colleagues. It has malignant clinical and histological features, remarkably rapid progression, atypical pathology like squamous cell carcinoma, and a poor prognosis. To date, 17 cases of malignant craniopharyngioma have been reported, most of which were secondary malignant tumors. In classic benign craniopharyngioma, adjunctive treatment after gross total removal is not necessary, but in cases of malignant tumors, adjunctive treatment is important. ⋯ Adjunctive gamma knife stereotactic radiosurgery and chemotherapy for malignant craniopharyngioma affects follow-up strategies, we propose the need for a revision to the World Health Organization classification regarding the evaluation of malignant craniopharyngioma.

Review Case Reports
Sciatica Caused by Venous Varix Compression of the Sciatic Nerve.
The authors report the case of a 76-year-old woman presenting with leg pain, numbness, and weakness mimicking a lumbosacral radiculopathy. ⋯ Variceal compression is a rare cause of extraspinal origin of lower extremity radicular pain. It should be considered if there is lack of correlation between radiologic findings and the clinical picture or if there is a failure of response to treatment of the assumed spinal cause.

Review Case Reports
Clipping of a Pediatric Pial Arteriovenous Fistula Located at Basilar Artery Tip Using a Hybrid Trapping-Evacuation Technique.
Intracranial pial arteriovenous fistulas (PAVFs) are rare cerebrovascular lesions with high mortality rates. We report a rare case of pediatric PAVF at the basilar artery tip and its treatment with surgical clipping aided by a trapping-evacuation technique in a hybrid operating room. ⋯ The successful obliteration of the lesion is reported. In addition, a brief review of literature comparing endovascular embolization, surgical disconnection, and hybrid technique for treatment of PAVF is included.

This study aimed to summarize the diagnosis, therapy, and prognosis of pituitary metastasis. ⋯ Pituitary metastasis is a rare disease. Its diagnosis depends on the clinical manifestations and radiologic results. The primary therapeutic method is surgery and subsequent radiotherapy and chemotherapy; however, the prognosis of this disease is poor.
