Clinical findings include dysfunction of the extraocular muscles innervated by the apoplejiaa nerve, with associated pupillary paralysis. The Journal accepts works written in Spanish or English. SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field. Neurosurgery journals Neurosurgery society Useful addresses.
There is no proven association between pituitary tumours and aneurysms but they may coexist due to the frequency of occurrence of both.
Aneurysms of the PCA are an important cause of oculomotor nerve lesions from compression of the nerve outside the central nervous system CNSas it passes near the junction of the PCA with the apopldjia portion of the internal carotid artery near the cavernous sinus. Continuing navigation will be considered as acceptance of this use.
Postgrad Med J ; Third nerve lesions from diabetes mellitus or hypertension typically spare pupillary function although it is not always possible to differentiate between medical and compressive causes of these lesions based entirely on apopeljia findings as in case two. The MRI showed a minimally enhancing sellar mass of predominantly high signal intensity on T1WI with a central hypo-intense area.

Case 1 A year-old Caucasian male presented with a two-day history of severe headaches and a one-day history of leftsided ptosis preceded by diplopia. Non-secreting tumours are usually large at diagnosis, frequently extending into the wpoplejia cistern with compression of the optic chiasm, producing visual field deficits, particularly bitemporal hemianopsia 6.

Ptosis as the early manifestation of pituitary tumour. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal’s impact. Visual field assessment revealed left nasal loss and mild constriction of the right nasal field. The MRI demonstrated the haemorrhage to greater advantage than did computed tomography.
Isolated unilateral ptosis due to superior rectus weakness without other ophthalmic muscle or papillary abnormality may be due to involvement of the superior branch of the oculomotor nerve in the orbit and is rarely the initial feature of a pituitary tumour with apoplexy 5,9, Treatment is mainly based on supportive measures intravenous fluids and steroids and surgical decompression in those cases with no response to medical treatment and progressive neurological impairment.
