Rosai-Dorfman Disease of rare isolated spinal involement: report of four cases and literature review.
Rosai-Dorfman disease (RDD) is a rare histioproliferative disorder that only occasionally involves the central nervous system (CNS). ⋯ Preoperative diagnosis of spinal RDD is still challenging because the lesion is usually a dura-based lesion that mimics a meningioma. Surgical resection is an effective treatment, and radiotherapy, steroid therapy, and chemotherapy have not shown reliable therapeutic efficiency.

The authors introduce a new fusion technique using 2 three-dimensional digital subtraction angiography images acquired by a flat-panel detector angiographic system to understand the detailed angioarchitecture of complex cerebral and spinal vascular malformations. ⋯ A fusion technique using two three-dimensional digital subtraction angiography is beneficial for preoperative planning and successful treatment in cases of complex cerebral and spinal vascular malformations.

Chiari I malformation (CM-I) is defined by cerebellar tonsillar herniation through the foramen magnum. Patients typically present with chronic complaints, including headache, dizziness, and numbness, although there are few reports in the literature of pediatric patients presenting acutely with neurological deficit caused by CM-I. We report a child who presented acutely with hemiparesis and magnetic resonance imaging findings consistent with CM-I and spinal cord edema. ⋯ This case highlights an unusual presentation of CM-I with neurological deficit related to spinal cord edema, possibly precipitated by the "water-hammer" effect of this patient's coughing fits. Providers should be aware of the acute presentations of CM-I.
