Neurological deficits commonly associated with anterior choroidal artery infarction (AChAI) include hemiplegia, hemisensory loss, and homonymous hemianopsia, while neuropsychological and perceptual deficits are uncommon. Prominent cognitive function impairment has rarely been reported. Here, we report a case of AChAI with prominent cognitive function impairment without motor deterioration. In contrast to the typical clinical features of AChAI, near complete and rapid motor recovery was observed, while cognitive impairment persisted despite rehabilitation therapy.

Cerebral developmental venous anomaly (DVA) is generally benign. However, we have experienced two cases of DVA causing symptoms. In the first case, the patient demonstrated DVA with venous infarction. DVA was visualized in the arterial phase using digital subtraction angiography (DSA), and was diagnosed as arterialized DVA. The second case presented as transient right homonymous hemianopia. DSA revealed venous congestion; the transient aggravation of venous congestion may have caused the symptom. DSA is useful for diagnosing the pathomechanism of symptomatic DVAs.

We report a case of immature teratoma arising at the suprasellar region in a 18 year-old-male who presented with bitemporal hemianopsia, nausea and polydipsia. The teratoma is a rare neoplasm consisting of 0.5% to 1.2% of all intracranial tumors. The clinical presentation, radiologic finding, pathology and treatment are briefly described with a review of other cases from the literature in view of clinical features and management.

We report a 39-year-old male who had generalized tonic-clonic seizure with loss of awareness. Investigations led to a diagnosis of a left temporal lobe tumor. He underwent resection of the mass with consequent loss of brain tissue in the temporal lobe and was found to have a complete right homonymous hemianopia in the immediate postoperative period. Macular ganglion cell analysis on optical coherence tomography (OCT) showed homonymous thinning affecting the inferonasal sector in the right eye and inferotemporal sector in the left eye. This case demonstrates transsynaptic retrograde degeneration through the interruption of the inferior optic radiation, and its corresponding effect on the structure and function of the affected retinal field. Temporal lobe lesions may cause not only a homonymous visual f ield defect contralateral to the side of the lesion but also result to homonymous sectoral thinning of the macular ganglion cell complexes in both eyes located ipsilateral to the side of the lesion.

The anterior middle fossa is the most common location of benign intracranial arachnoid cysts. In the adult, headache, temporal bulging, and mild proptosis are the usual presenting complaints, although seizures and contralateral weakness have been described. Bitemporal hemianopsia associated with this lesion has not been noted previously. Herein we describe the patient with bitemporal hemianopsia associated with sylvian fissure arachnoid cyst. Cystoperitoneal shunt was beneficial. The etiology, histology, and suggested therapy of other patient with arachnooid cyst are also discussed.

Giant serpentine aneurysm(GSA) is a giant aneurysm containing a serpentine channel which enters and exits at separate sites and is continuous with the parent vessel. This 33-year-old man with a two-year history of frontal headache presented with bitemporal hemianopsia three months before admission. Suprasellar mass of computed tomography revealed a giant(3X2.5X2cm) mixed density, mimicking a brain tumor. Cerebral magnetic resonance images showed a flow void within the mass, and this was consistent with the serpentine vascular channel demonstrated by angiography. The aneurysm was revealed by surgery involving the frontobasal interhemispheric approach, left A1 & A2 were clipped and the mass of the aneurysm was removed in toto an aneurysmorrhaphy was constructed, and to preserve the distal blood flow to the left A2, the patient made an unevenful recovery.
