Background: Rosai-Dorfman Disease (RDD) is a rare idiopathic non-neoplastic histioproliferative disease characterized clinically by massive painless cervical lymphadenopathy, fever and weight loss. Extranodal involvement has also been recognized. Central nervous system (CNS) manifestations are extremely rare and patients with intracranial involvement usually present with clinical and radiological findings suggestive of a meningioma.
Case Description: We report our experience in the management of three patients with RDD. Two patients had dural based lesions, radiologically in favour of a meningioma, and one patient had a parenchymal lesion suggestive of a tuberculous granuloma. Treatment consisted of total excision in one case, and subtotal excision followed by conventional radiotherapy in two cases. The diagnosis was confirmed by histopathology and immunochemistry which is essential for a definite diagnosis of RDD.

Center for Cranial Base Surgery, Hospital Angeles Pedregal, Mexico City, Mexico.
Article Synopsis
- Rosai-Dorfman disease (RDD) is a rare histiocytosis often presenting with systemic symptoms, but this case highlights its unusual progression to the brain after skull base involvement.
- The presented case involves a 57-year-old male with severe headaches and a tumor mass affecting several areas, culminating in surgical intervention that revealed RDD.
- The study emphasizes the need for timely surgical treatment to prevent local and systemic disease progression, despite RDD typically being regarded as benign.
Study protocol of the ASTOP trial: A multicenter, randomized, double-blind, placebo-controlled trial of presurgical aspirin administration for the prevention of thromboembolic complications of coil embolization for ruptured aneurysms.
PLoS One

Department of Endovascular Surgery, Tokyo Medical and Dental University, Tokyo, Japan.
Article Synopsis
- Thromboembolism is a critical concern in patients undergoing endovascular treatment for ruptured cerebral aneurysms, and administering antiplatelet agents like aspirin before the procedure may lower this risk.
- The study, called ASTOP, is a multicenter, randomized, double-blind trial involving 484 patients, comparing the effects of 200 mg of aspirin versus a placebo prior to treatment.
- Primary outcomes will focus on measuring thromboembolic complications and ischemic lesions during the procedure, while secondary outcomes will assess cerebral ischemic events, bleeding incidents, and patient functional status after 90 days.
Coil Embolization for Cerebral Aneurysm Using Low Pulse Rate Fluoroscopy.
Neurol Med Chir (Tokyo)

Department of Neurosurgery, Osaka University Hospital.
Although coil embolization is commonly perceived as a minimally invasive procedure, the associated radiation exposure cannot be disregarded. To date, no specific study has investigated radiation exposure during coil embolization. This study aimed to investigate the potential of lowering the pulse rate to decrease radiation exposure during coil embolization while maintaining patient safety.
