ABSTRACT
Mycotic aneurysms of the intracavernous segment of the internal carotid artery secondary to cavernous sinus thrombophlebitis are exceedingly rare. The authors report a case with mycotic pseudoaneurysm in the cavernous portion of the internal carotid artery with clinical and angiographic evidence cavernous sinus thrombosis. The strikingly development of the pseudoaneurysms was demonstrated by digital subtraction angiography.

Herpes zoster is an acute, self-limited disease of infectious origin. It is characterized by grouped vesicular lesions on an erythematous base distributed over several dermatomes as well as single. In some cases the patients can be found to have an identifiable risk factor such as old age, malignancy, irradiation, chemotherapy, immunosuppresive therapy and trauma. The majority of cases are self-limited and resolved completely. However it may have serious complication. We reviewed 369 cases of herpes zoster to determine the distribution of lesions, incidence of postherpetic neuralgia, associated disorders, and the age. 134 cases (36.1%) of 369 cases with herpes zoster were associated with chronic disorders. The complications of herpes zoster were developed in 71 cases (19.2%) and postherpetic neuralgia (PHN) was the most commom complication. The frequency and severity of postherpetic neuralgia were proportional to age. There was a predilection of the involvement in thoracic dermatomes, lumbar dermatomes and ophthalmic division of trigeminal nerve in decreasing order of frequency. The incidence and duration of postherpetic neuralgia are significantly related to age.

Of 129 patients with carbon monoxide (CO) poisoning, 62(48.0%) had characteristic computed tomographic (CT) findings. The most common finding, seen in 42 patients, was low-density in the cerebral white matter, and the second characteristic feature, seen in 33 patients, was low-density in both globus pallidi. Abnormal CT findings tended to increase in accordance with the duration of unconsciousness during acute CO poisoning, but such findings occurred even when the mental state was clear during acute illness. The prognosis of acute CO poisoning depended on low-density lesions of the cerebral white matter rather than those of the globus pallidus. There also seemed to be a significant correlation between the cerebral white matter changes in the initial CT scan and the development of delayed neurologic sequelae after acute CO poisoning, particularly in middle age or older patients, but no correlation between the CT findings and the clinical outcome of delayed neurologic sequelae.

Albinism is associated with neural anomalies including foveal hypoplasia and aberrant optic pathway projection that result in a variety of oculomotor instability. We present a 38-years-old man with oculocutaneous albinism who had horizontal jerk-type nystagmus, which showed a reverse in direction by any extraneous light stimulation which was documented by electronystagmogram. The mechanism of the nystagmus in this case is uncertain. These findings in albinism have not been reported previously, to our knowledge, and suggest a defect in the visual pathway system.
