Iliac artery aneurysm causing isolated superior gluteal nerve lesion.

Lesions of the superior gluteal nerve (SGN) lead to weakness of hip abduction, manifesting itself as a gait abnormality, with contralateral tilting of the pelvis with each step. Causes are numerous and may occur at different anatomical locations before the nerve enters the suprapiriform foramen, in the foramen itself, or after the nerve has exited the foramen. This case report describes an SGN lesion by a large iliac artery aneurysm in a patient presenting with a gait disorder.

Intravascular lymphomatosis: a clinicopathological study of three cases.

In patients with intravascular lymphomatosis (IL) a broad spectrum of neuro-psychiatric disorders including dementia, focal neurological signs and seizures has been reported. Clinical diagnosis is difficult since neuroimaging findings are nonspecific. The clinical histories, biopsy and autopsy findings of three patients with IL, one with brain biopsy, are described. Two of them presented with rapidly progressive, fluctuating dementia. The third patient suffered from seizures followed by aphasia. Histology revealed large-cell lymphoma of the B cell type. The prognosis of IL, in general, is poor.

Dissociated unilateral convergence paralysis in a patient with thalamotectal haemorrhage.

A 47 year old male was admitted in a comatose state. CT scan showed a haemorrhage in the right pulvinar thalamus descending into the right part of the lamina quadrigemina. He presented with anisocoria, prompt bilateral pupillary light reaction, and unilateral convergence paralysis contralateral to the lesion in combination with upward gaze palsy. During an observation period of two months, the convergence reaction returned to normal. MRI showed a lacunar lesion ventral to superior right colliculus. Angiography revealed an arteriovenous malformation (right posterior cerebral artery--sinus rectus) as the possible cause of the haemorrhage.

Angiotropic lymphoma (malignant angioendotheliomatosis) presenting with rapidly progressive dementia.

An 87-year-old male presented with rapidly progressive dementia, disorder of consciousness and myoclonus, suggesting Creutzfeldt-Jakob disease, but with nonspecific EEG and negative CT findings. Autopsy revealed a malignant angiotropic lymphoma with accumulation of tumor cells within small vessels of the brain and visceral organs. Immunohistochemistry disclosed a large cell lymphoma of B cell type.
