  • We report a case of 70-year-old man with glioblastoma presenting as acute encephalitic illness. The patient exhibited sudden onset of cognitive impairment and headache for 2 days. Initial brain MRI showed left temporal lobe hyperintensity, and cerebrospinal fluid cytology revealed a mild pleocytosis. The patient had initially improved after medical treatment with a presumptive diagnosis of herpes simplex encephalitis (HSE). After 8 months, the patient complained of recurrent seizures. A follow-up brain MRI revealed marked increases in size and surrounding perilesional edema in the left temporal lesion on T2-weighted images and a new contrast-enhancing lesion on gadolinium-enhanced T1-weighted images. Stereotactic brain biopsy revealed a glioblastoma. The atypical encephalitic presentation of glioblastoma should be considered if definitive evidence for the diagnosis of HSE cannot be obtained.

  • The authors encountered a case of simultaneous radiation-induced multiple meningiomas and ventriculoperitoneal [VP] shunt-related pneumocephalus. A 35-year-old man, who had undergone surgery for medulloblastoma 21 years previously and subsequently received high dose craniospinal irradiation with adjuvant chemotherapy and later underwent a VP shunt because of hydrocephalus, presented with a severe headache and weakness of both lower extremities. Computed tomography showed an air pocket lesion in the left temporal lobe and a large amount of pneumocephalus with a bony defect of the left tegmen tympani. In addition, a 3 cm sized well enhancing mass was noted in the in the right middle cranial fossa and additional small enhancing nodule in the left frontal pole. He was treated by left temporal craniotomy and repair of the bony and dural defects of the left tegmentum tympanum through extradural and intradural approaches, respectively. Afterwards, he underwent right temporal craniotomy and gross total removal of a rapidly growing right middle fossa mass and a left frontal mass. The histological examination was consistent with atypical meningioma, WHO grade II. In conclusion, physicians have to consider the serious long term complications of high dose radiation therapy and VP shunt placement and need to perform the neuroradiologic follow-up after such treatments for several decades.

  • A 67-year-old male presented with left temporal hemianopsia and left hemiparesis. A contrast-enhanced magnetic resonance image revealed a $4.5{\times}3.5{\times}5.0cm$ rim-enhancing mass with central necrosis and associated edema located in the left occipital lobe. Of positron emission tomography and abdominal computed tomography, a 9-cm mass with poor enhancement was found in the right hepatic lobe. Craniotomy and right hemihepatectomy was performed. The resected specimen showed histological features and immunochemical staining consistent with a metastatic neuroendocrine tumor (NET). Four months later, the tumors recurred in the brain, liverand spinal cord. Palliative chemotherapy with etoposide and cisplatin led to complete remission of recurred lesions, but the patient died for pneumonia. This is the first case of a metastatic brain NET originating from the liver. If the metastatic NET of brain is suspicious, investigation for primary lesion should be considered including liver.

  • Hippocampal sclerosis (HS) is one of the most common features of intractable temporal lobe epilepsy. Generally it can be identified through brain magnetic resonance imaging (MRI) with high degree of sensitivity and specificity. Typical brain MRI findings of HS are hippocampal atrophy with hyperintense signal confined to the lesion. On the other hand cortical dysplasia exhibits blurring of the gray-white matter junction and abnormal white matter signal intensity. We present a case where preoperative brain MRI strongly suggested the presence of diffuse cortical dysplasia in the left temporal lobe but postoperative pathology revealed the temporal lesion to be unremarkable except for hippocampal sclerosis.

  • Purpose: We presented with a patient with traumatic brain injury who showed a transcallosal ipsilateral motor pathway from unaffected motor cortex to affected extremities, as evaluated by diffusion tensor tractography (DTT). Methods: One patient and six age-matched normal subjects were enrolled. A 42-year-old left hemiparetic male who suffered from brain injury by motor vehicle accident 9 years ago showed a leukomalactic lesion in the right corona radiata and parieto-temporal lobe. His left extremities were completely paralyzed initially, but recovered slowly over 2 years. At the time of the evaluation, he was able to grasp and release an object, and to walk with spastic gait pattern. DTT was performed using 1.5 T with a Synergy-L Sensitivity Encoding head coil. DTT was obtained with termination criteria of FA <0.2 and an angle change > $45^{\circ}c$. Results: The motor tracts of the unaffected (left) hemisphere of the patient and control subjects originated from the motor cortex and descended along the known corticospinal tract without any transcallosal tract. By contrast, the tract of the affected (right) hemisphere originated from the left premotor cortex, descended through the left corona radiata, and then crossed the mid-portion of the corpus callosum. The tract then descended through the known corticospinal tract pathway to the right medulla. Conclusion: We conclude that the transcallosal ipsilateral motor pathway from the unaffected hemisphere appeared to contribute to the motor recovery in this patient.

  • A 4-year-old girl with Panayiotopoulos syndrome presented with a history of 4 prolonged autonomic seizures. The clinical features of her seizures included, in order of occurrence, blank staring, pallor, vomiting, hemi-clonic movement on the right side, and unresponsiveness. A brain magnetic resonance imaging (MRI) showed a slightly high $T_2$ signal in the left hippocampus. Interictal electoencephalogram revealed spikes in the occipital area of the left hemisphere. We analyzed the current-source distribution of the spikes to examine the relationship between the current source and the high $T_2$ signal. The current source of the occipital spikes was not only distributed in the occipital area of both cerebral hemispheres, but also extended to the posterior temporal area of the left hemisphere. These findings suggest that the left temporal lobe may be one of the hyperexcitable areas and form part of the epileptogenic area in this patient. We hypothesized that the high $T_2$ signal in the left hippocampus of our patient may not have been an incidental lesion, but instead may be related to the underlying electroclinical diagnosis of Panayiotopoulos syndrome, and particularly seizure. This notion is important because an abnormal $T_2$ signal in the hippocampus may represent an acute stage of hippocampal injury, although there is no previous report of hippocampal pathology in Panayiotopoulos syndrome. Therefore, long-term observation and serial follow-up MRIs may be needed to confirm the clinical significance of the $T_2$ signal change in the hippocampus of this patient.

  • Intractable hiccups are those which persist for more than one month and can often occur in patients with disorders of the central nervous system, such as stroke, epilepsy, or brain tumor. An 80-year-old male patient undergoing conservative hemodialysis for diabetic nephropathy, recently developed paralysis and dysphagia due to central nervous system complications including stroke and epilepsy. He was admitted to the ◯◯ Oriental Medicine Hospital, and treated with herbal medicine (Gyulpijugyeo-tang, Jeonssiigong-san, and Ijin-tang) and electrical acupuncture for 30 days. No side effects were observed during hospitalization. The frequency and duration of hiccups were measured daily and found to reduce, and the effect persisted during his admission. The patient took no other nervous system drugs. In conclusion, Korean medicine like gyulpijugyeo-tang and acupuncture can be effective for patients with intractable hiccups who cannot use alternative drugs or treatment, because of other complications.
