Contrast agent neurotoxicity mimicking subarachnoid haemorrhage

We are presenting an unusual complication of the intravascular angiographic contrast agent in a 58-year-old male patient with the diagnosis of subarachnoid haemorrhage [SAH]. After cerebral angiography, his clinical condition deteriorates. Computed tomography scan of the brain showed the picture of SAH due to the contrast agent of extravasation. Appropriate treatment, with avoidance of additional contrast agent administration was resolved in complete neuroradiological recovery within 2 days

Primary spinal intramedullary primitive neuroectodermal tumour in an adult

Primary spinal primitive neuroectodermal tumour [PNET] is believed to be very rare. A review of the available literature revealed 14 cases of spinal PNET, which affected the paediatric age group but no previously reported cases involved an adult. A 42-year-old patient presented with weakness of both lower limbs and signs of upper motor neuron lesion. Intramedullary PNET was discovered after neurological deterioration following C3-4, C5-6 and C6-7 discectomy. Patient received postoperative radiotherapy, however, he died 8 months later from brain metastasis. As this is the first case of its kind in the literature, we believe it is worth reporting to point out the possibility of the existence of such a lesion in the spinal cord

Tuberculoma of the optic nerve

This is a case of 50 year-old Saudi lady complaining of progressive loss of vision in both eyes, associated with a constant, steady headache. She was referred to King Fahd Hospital of the University for evaluation. A computed tomography scan and magnetic resonance imaging were done and a craniotomy was planned. A biopsy from the left optic nerve showed evidence of a granulomatous lesion, which proved to be tuberculosis. In this report, we discuss the clinical and pathological findings in a case of tuberculosis of the optic nerve. A review of the literature indicates that this is the first report of its kind from this area. With the resurgence of tuberculosis throughout the world, this rare aetiology as a cause of visual loss should be kept in mind
