| Summary: | Abstract Lower limb weakness is usually a feature of ruptured anterior communicating (ACom) aneurysms due to spasm of the anterior cerebral arteries. Paraclinoid aneurysms, in addition to other cardinal features of subarachnoid haemorrhage (SAH), usually present with headache and visual field defects due to compression of the optic pathway. We report a case of left paraclinoid aneurysm presenting with right lower limb weakness and gyrus rectus hematoma without SAH. The aneurysm was long, passing beneath the optic nerve to emerge in the inter-optic cistern, leading to such atypical presentation. The aneurysm was clipped successfully after drilling the clinoid. As per our knowledge, such a clinical presentation of paraclinoid aneurysm has not been reported in the literature till date.
