A 73 year-old man experienced left monocular blindness and transient right hand clumsiness. A left carotid arteriogram was performed 4 days after admission. Immediately following arteriography, there was a right hemiparesia and dysphasia. After 24 hours, the abnormalities resolved. The patient was treated with heparin. During the following weeks, he became gradually drowsy and confused. Pseudo-bulbar palsy and astasia appeared after a fluctuating but progressive neurological course. The combination of systemic symptoms, high sedimentation rate, renal failure, livedo reticularis and purple toes suggested necrotizing angiitis. With corticosteroid treatment, there was a slight improvement of systemic symptoms. Cholesterol emboli were seen in both fundi. Cholesterol embolization was proved by identifying the biconcave cholesterol crystal clefts in muscle and skin biopsies. The subsequent course was marqued by continuous neurological deterioration. The patient became stuporous and died 7 months after admission. Despite the lack of central nervous system pathological study, the clinical picture was highly suggestive of cerebral cholesterol embolism. A few cases have been reported, with only eight well-documented clinical descriptions. Clinical signs and symptoms were closely similar to those of the present case. Anticoagulant therapy of cholesterol emboli has been unsuccessful. In the present case, the onset of embolization was temporally related to anticoagulation.

Delirium may present with hyperactive, hypoactive or mixed clinical pictures. The signs of hypoactive delirium are lethargy, confusion, apathy, hypersomnia, muttering, difficulty in maintaining attention, and difficulty in understanding and performing commands. Valproate is commonly used for the treatment of epilepsy and bipolar disorders. It is also used for the management of alcohol withdrawal delirium and agitative-aggressive deliriums. However, few reports are available about the valproate-induced delirium. In this report, we present a 46 years-old woman with bipolar disorder for 14 years. During her last two hospital admissions, she had been diagnosed with manic episode with psychotic features and she had received valproate. She experienced three hypoactive delirium episodes lasting 2-3 days throughout the treatment period of first week. The patient predominantly had the following signs; vomiting, hypersalivation, confusion, drowsiness, dysphasia, and hypoactivity. At the first day of delirium episode, serum valproate level was found to be within the therapeutic range (98.4, 117.1, and 65.6 mug/ml; respectively). In addition, she had normal results of cranial MRI, complete blood count, urine analysis, electrocardiogram, ALT, AST, albumin, bilirubin, BUN, creatinine and electrolytes. The serum ammonia level of the patient could not been measured due to limitations of laboratory facilities. The patient's consciousness improved dramatically 2-3 days after cessation of valproate. In conclusion, valproate can induce delirium at therapeutic blood levels in some patients via various mechanisms and this side effect has to be considered during valproate use.

Herpes simplex virus (HSV) encephalitis is a rare but often fatal disease if left untreated. A 50-year-old woman was admitted with lethargy, confusion, dysphasia and cough. MRI brain demonstrated bilateral temporal and perisylvian hyperintense signal abnormality extending into the cingulate gyrus, typical of HSV encephalitis. However, there was also signal abnormality involving the right thalamus, indicating thalamic involvement. EEG and cerebrospinal fluid PCR confirmed HSV encephalitis. The patient was started on intravenous acyclovir resulting in marked improvement. Adequate assessment and prompt treatment of HSV encephalitis will aid in achieving adequate recovery. Radiological investigation plays a crucial role in diagnosis with typical MR features a useful aid to diagnosis. HSV encephalitis classically involves the medial temporal lobes, insula and cingulated gyri. The basal ganglia and thalami are nearly always spared. We present a very rare case of HSV encephalitis which involved the right thalamus.

After being admitted to hospital with atypical chest pain, a 61-year-old woman was noted to become lethargic and confused. She also developed global dysphasia. MRI was suggestive of encephalitis, and lumbar puncture was positive for cytomegalovirus (CMV) PCR. The patient was treated with intravenous ganciclovir and subsequent oral valganciclovir and she gradually made a reasonable recovery. While this infection is usually closely linked to immunosuppression, the patient was found to be HIV negative, and was not on any immunosuppressive therapy. Going through the patient's medical history revealed two possible risk factors which might have led to the development of CMV encephalitis: immunosuppression secondary to underlying poorly controlled diabetes mellitus; and previous admission to the intensive care unit which might have lead to CMV reactivation.
