We present a case of hydrocephalus as the primary manifestation of neurosarcoidosis. Sarcoidosis is a rare disease in Korea and its incidence is much lower than that of tuberculosis. Diagnosis is made by pathologic findings and by exclusion of other granulomatous disorders. Neurosarcoidosis is observed in approximately 5% of sarcoidosis. Its common manifestations are facial palsy (50% of patients with neurosarcoidosis) and optic neuritis. Hydrocephalus is a very uncommon reported finding. Although the typical presentation of sarcoidosis such as facial palsy is not a diagnostic dilemma, more atypical presentations such as hydrocephalus with altered mentality in a tuberculosis patient can lead to a misdiagnosis.

A differential diagnosis between neurosarcoidosis and neurosyphilis is particularly problematic in patients with a positive serologic result for syphilis. We report here a patient with a solitary cavernous sinus sarcoidosis who had a history of syphilis and showed rapidly progressing cavernous sinus syndrome. A transsphenoidal biopsy was performed and a histopathologic examination revealed a non-caseating granuloma with an asteroid body. His facial pain disappeared after steroid therapy. He received oral prednisolone for one year. A follow-up magnetic resonance imaging of the brain revealed resolution of the mass over the cavernous sinus. Particularly in patients with a history of syphilis, neurosyphilis should be included in a differential diagnosis of neurosarcoidosis.

A 31-year-old man was admitted to our hospital due to hydrocephalus with neurosarcoidosis. Ventriculo-peritoneal shunting was performed in the right lateral ventricle with intravenous methylprednisolone. Subsequently, after 4 months, additional ventriculo-peritoneal shunting in the left lateral ventricle was performed due to the enlarged left lateral ventricle and slit-like right lateral ventricle. After 6 months, he was re-admitted due to upward gaze palsy, and magnetic resonance image showed an isolated fourth ventricle with both the inlet and outlet of fourth ventricle obstructed by recurrent neurosarcoidosis. Owing to the difficulty of using an endoscope, we performed neuronavigator-guided ventriculo-peritoneal shunting via the left lateral transcerebellar approach for the treatment of the isolated fourth ventricle with intravenous methyl prednisolone. The patient was discharged with improved neurological status.

A 31-year-old man presented with dull headache and memory disturbance lasting for one week. Computed tomographic scans revealed acute hydrocephalus. The cerebrospinal fluid contained 53 leukocytes/$mm^3$, with a mononuclear preponderance and no erythrocytes. Magnetic resonance imaging revealed hydrocephalus and leptomeningeal enhancement. Magnetic resonance angiography and digital subtraction angiography showed supraclinoid occlusion of the right internal carotid artery, which resembled unilateral moyamoya disease. Neuroendoscopic biopsy of a lesion in the septum pellucidum revealed noncaseating granulomas, which was consistent with sarcoidosis. The patient was successfully managed with intravenous methylprednisolone and ventriculoperitoneal shunting. To our knowledge, this is the first case of moyamoya-like vasculopathy associated with neurosarcoidosis.

유육종증은 다발성 비건락성 육아종 형성을 특징으로 하는 원인 미상의 전신 질환으로 주로 폐, 피부, 림프절 등의 장기를 침범하며, 신경계 침범은 상대적으로 드문 것으로 알려져 있다. 저자들은 다른 신경학적 증상 없이 단기 기억장애만을 특징으로 하는 신경유육종증이 병발한 폐유육종증 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

A case of parasagittal meningioma en plaque with a peculiar clinical presentation is reported with a review of the literature. A 72-year-old woman presented with dysphasia and right hemiparesis. Computed tomography and magnetic resonance imaging demonstrated focal edema of left frontal lobe and a thick sheet-like parasagittal enhancing lesion with extension along the falx cerebri and adjacent sulcal enhancement. Differential diagnosis included idiopathic hypertrophic pachymeningitis, meningeal neurosarcoidosis, metastasis and meningioma en plaque. Cerebral angiography revealed occlusion of the anterior one-third of the superior sagittal sinus as well as a faint tumor blush supplied from the anterior branch of the middle meningeal artery. At surgery, the tumor invading the dura and skull was removed totally but the tumor invaded into the superior sagittal sinus was removed subtotally. The tumor was confirmed to be a transitional meningioma on pathological examination.
