We reported a rare case of the posterior inferior cerebellar artery arising from the internal carotid artery directly. A 33-year-old male was admitted to our hospital with the complaint of throbbing type headache. CT showed no abnormal findings. ⋯ We diagnosed it as a kind of variant of the persistent primitive hypoglossal artery. The persistent primitive hypoglossal artery is composed of the proximal segment derived from the primitive hypoglossal artery, and the distal segment consisting of portions of the lateral anastomotic channels (primitive lateral basillo-vertebral anastomosis) which give rise to the posterior inferior cerebellar artery. We speculated that this variant resulted from the persistence of the proximal segment, which communicated with the stem of the posterior inferior cerebellar artery via the distal segment, and next, the disconnection of the posterior inferior cerebellar artery origin with the vertebral artery due to the aplasia of right vertebral artery and the involution of the distal segment connected to the basilar artery.

Review Case Reports
[Two cases of generalized tetanus presenting with dysphagia as an initial symptom].
We describe two patients with generalized tetanus, a 60-year-old man and a 76-year-old woman, presenting with dysphagia as an initial symptom of the disease. Eighty percent of patients with generalized tetanus manifest dysphagia on admission to a hospital. However, dysphagia is rare as an initial symptom. ⋯ Therefore, elderly people are considered susceptible to tetanus. We suggest that tetanus should be considered in the differential diagnosis of dysphagia particularly in elderly patients. We also suggest that treatment of tetanus should be initiated immediately, because tetanus still has a high mortality rate at present.

Examination of a 58-year-old woman who had developed severe upper back pain showed left peripheral type of facial nerve palsy, sensory disturbance of limbs and body trunk (Th7-9), cerebellar ataxia and generalized hyporeflexia. Upper back pain increased at night and was resistant to NSAIDs, antianxiety agents, opioids, and corticosteroids. Concentrations of serum CK and cerebrospinal fluid total protein were elevated. ⋯ However, only one GBS patient with initial severe upper back pain has been reported. Although the precise mechanism of pain in GBS remains unclear, EMG findings lead us to surmise our patient's pain originated from the nerve roots. Limb and back pain should therefore be taken into account for the diagnosis and treatment of GBS patients.

Despite advances in radiation and chemotherapy along with surgical resectioning, the prognosis of patients with malignant glioma is poor. Among the new treatments currently being investigated for malignant glioma, immunotherapy is theoretically very attractive, since it offers the potential for high tumor-specific cytotoxicity. ⋯ Dendritic cell-based immunotherapy strategies appear promising as an approach to successfully induce an antitumor immune response and increase survival in patients with glioma. The development of methods for manipulating dendritic cells for the purpose of vaccination will enhance the clinical usefulness of these cells for biotherapy for malignant glioma.

Case Reports
[Cheiro-oral syndrome due to a cortical infarction in the precentral gyrus: a case report].
We report a 65-year-old woman with sudden onset of paresthesia on the left side of the lip and left thumb. Neurological examinations did not demonstrate any disturbance of higher brain function or motor function except for subjective thermohyperesthesia of the left thumb. Brain MRI demonstrated a small high intensity lesion on T2-weighted images (T2 WI) and diffusion-weighted images (DWI) in the right anterior precentral gyrus. ⋯ Not only lesions of the postcentral gyrus as a primary sensory cortex but also those of the precentral gyrus or opercula causing COS were described in previous reports, indicating that the hand and mouth sensory areas may be widely distributed. Cortical mapping studied by electrical stimulation through subdural grid electrodes also supports this finding. Further examination of the relation between neurological symptoms and localization on MR images such as DWI is needed to clarify the distribution of the sensory cortex.
