Eight-hundred eleven case records of patients with hemorrhagic fever with renal syndrome (HFRS) caused by Puumala virus were reviewed, and particular attention was given to data regarding severe neurological manifestations. The most common symptoms were headache (97%), blurred vision (40%), and vomiting (31%); 27% of the patients had all three. Nine patients (1%) had severe neurological manifestations: meningism and cerebral hemorrhage occurred during the first week of illness, whereas epileptiform seizures and urinary bladder paralysis developed during the second week. In terms of the severity of renal failure, as evidenced by maximum serum creatinine levels, there was no difference between patients with or without severe neurological conditions. There was one fatal case due to cerebral hemorrhage; the other patients with severe neurological manifestations clinically recovered and did not have any neurological signs during 6 months of follow-up. HERS caused by Puumala virus, or a variant of it, may be associated with severe, potentially life-threatening neurological complications.

Although meningismus or meningitis are known to occur after pituitary surgery; meningo-encephalitis caused by Streptococcus pneumoniae following a trans-sphenoidal approach has not been previously reported. A 56-year-old man presented with blurred vision. Two days after uneventful surgery, the patient became hyperpyrexic which progressed to confusion and lethargy within 48 hours. Spinal fluid cultures revealed Streptococcus pneumoniae. The patient was treated appropriately and made an uneventful recovery. MR images showed persistent changes within both frontal lobes. This case further suggests that peri-operative antimicrobial chemoprophylaxis may not save the patient from serious surgical infections.

Vogt-Koyanagi-Harada (VKH) disease is a systemic disease consisting of bilateral granulomatous panuveitis combined with cutaneous and neurologic manifestations. However, there have been few reports of brain magnetic resonance imaging (MRI) in VKH disease. A 54-year-old Korean woman presented with severe periorbital pain, blurred vision and meningismus. Ophthalmologic examination disclosed bilateral optic disc edema with peripapillary nerve fiber hemorrhages. Lumbar puncture revealed monocytic pleocytosis. After a diagnosis of VKH disease was made, the patient was treated with high-dose corticosteroid. Brain MRI showed diffusely thickened posterior ocular walls with retinal detachment and perineural infiltrative changes along the optic nerves and adjacent pachymeningeal enhancement of the anterior temporal lobes bilaterally. We report a case of VKH disease with panuveitis and meningeal involvement of the anterior temporal lobe detected by brain MRI.
