Intracranial Rosai—Dorfman disease treated with microsurgical resection and stereotactic radiosurgery: Case report
2003
✓ Sinus histiocytosis or Rosai—Dorfman disease (RDD) is a rare idiopathic histioproliferative disorder typically characterized by painless cervical lymphadenopathy, fever, and weight loss. Extranodal, intracranial disease is uncommon. In this report the authors describe the first case of intracranial RDD treated with stereotactic radiosurgery after resection. This 52-year-old man with known RDD presented with a 7-day course of fever, headache, diplopia, left facial paresthesias, and difficulty swallowing. No cranial nerve deficits were evident on examination, but right submandibular and inguinal node enlargements were noted. On neuroimaging, the patient was found to have a homogeneously contrast-enhancing petroclival lesion with extension into the left cavernous sinus. The patient underwent a combined left petrosal craniotomy and partial labyrinthectomy with duraplasty for biopsy sampling and partial microsurgical resection of the lesion. Microscopic examination of the biopsy specimen revealed the presenc...
