Two Cases of Invasive Aspergillosis of Sino-nasal Origin

Cerebral aspergillosis is a rare condition that affects primarily the immunocompromised host. Most of cerebral aspergillosis is developed by hematogenous dissemination from extracranial foci, but aspergillosis of sino-nasal origin rarely affects the CNS. In case 1, wel symptom of tumor recurrence was unilateral numbness of the chin. A 65-year-old male was admitted because of paresthesia around the left chin and left lower lip. Neurologic examination revealed hypesthesia on the left side of chin, lower lip and buccal mucous mem-brane. Bone scan (Tc-99m MDP) showed focal hot uptakes on the left mandible and left first rib. Brain CT with bone window setting showed a focal osteolytic lesion in the bone marrow of the left mandibular canal without destruction of bone cortex. Both coronal T1 weighted image and axial T2 weighted image showed focal low signal intensities on the left ramus. The pathophysiologic mechanism could be understood by identification of the pathologic focus.

Two Cases of Sporadic Encephalitis Lethargica

We present two patients with clinical features suggestive of a hyperkinetic form of encephalitis lethargica described by von Economo. While undergoing treatment for viral meningoencephalitis, they both developed comatose mentality, oromandibular dyskinesia, chorea, myoclonic jerk, oculogyric crisis, opistotonus, respiratory failure, and autonomic dysfunction. One patient died of autonomic failure while the other improved several months later. In both patients, cerebrospinal fluid exmamination revealed only pleocytosis. A brain MRI and EEG showed no specific findings. In order to control severe hyperkinetism and autonomic failure, medical treatments including L-dopa, clonazepam, and steroid pulse therapy were administereed in both cases while electroconvulsive therapy was tried in one of the cases. However, they all failed. These cases and previous reports informed us of the presence of sporadic form of encephalis.
