We describe the case of a 14-year-old Caucasian male, a resident in the Democratic Republic of the Congo, who was observed in Portugal with severe Plasmodium falciparum malaria with high-level parasitemia and severe thrombocytopenia. The course was complicated by bilateral sixth cranial nerve palsy during acute malaria, followed by the appearance of delayed cerebellar ataxia during the recovery...

The author reports on the case of a 60-year-old woman who presented with recurrent left sixth cranial nerve palsy. The patient was initially hospitalized to rule out an aneurysm of the internal carotid artery. Angiography revealed segmental dilation of the internal carotid artery and a persistent primitive trigeminal artery (PPTA) that coursed through the dorsolateral cavernous sinus, opening i...

BACKGROUND Pituitary adenoma may present with neuro-ophthalmic manifestations and, typically, rapid tumor expansion is the result of apoplexy. Herein, we present the first case of an isolated sixth cranial nerve palsy as initial feature of a rapidly expanding ACTH positive silent tumor without apoplexy. CASE PRESENTATION A 44 year old female with a history of sarcoidosis presented with an iso...

acute idiopathic peripheral facial paralysis (bell's palsy) is the most common disorder of the facial nerve. most patients recover completely, although some have permanent disfiguring facial weakness. many studies have attempted to identify an infectious etiology for this disease. although the cause of bell's palsy remains unknown, recent studies suggest a possible association with herpes simpl...

Colloid cysts are benign slow-growing cystic lesions located on the roof of the third ventricle that usually present with symptoms related to gradual rise of intracranial pressure. They mostly remain asymptomatic and sometimes grow progressively and cause diverse symptoms associated with increased intracranial pressure such as headache, diplopia, and sixth cranial nerve palsy. Here we report a ...

CLINICAL FEATURES The presentation of CVT can be acute, subacute or chronic. The presenting symptoms are grouped into four major syndromes (Bousser et al. 1997): • isolated intracranial hypertension – headache, visual obscurations, vomiting, papilloedema ± sixth nerve palsy (Biousse et al. 1999); • focal syndrome – focal or generalized seizure and/or a focal defi cit such as monoor hemi-paresis...

We present a case with recurrent orbital myositis sequentially affecting both lateral rectus muscles separately. In the first episode, the absence of the required symptoms for the diagnosis of orbital myositis led to the erroneous diagnosis of sixth nerve palsy. Eventually, the correct diagnosis was established with cerebral MR imaging. Orbital myositis should be included in the differential di...
