Computed tomographic scanning is an excellent modality for evaluation of most orbital and
intracranial tumors
and strokes. However, MR scanning is definitely superior to CT when evaluating for multiple sclerosis, posterior fossa lesions (evaluation of gaze palsies, internuclear
ophthalmoplegia
, and downbeat nystagmus), or when assessing an area where sagittal scanning is important (chiasmal lesions). Magnetic resonance has increased specificity when the CT is equivocal. Although MR and CT may be complementary in the information they provide, many clinical studies have shown MR to be superior to CT in evaluating cerebral infarctions, hematomas, the intracanalicular optic nerve, optic chiasm, sella turcica, and the cavernous sinus. Magnetic resonance generally has replaced metrizamide CT cisternography as the procedure of choice for evaluating the suprasellar cistern and posterior fossa. Computed tomography is still preferable for major trauma, especially involving acute fractures and hematomas, although MR is more sensitive to the more subtle intracerebral lesions, such as shear injuries and subdural hematomas, that may provide prognostic information. Computed tomography also is preferred in situations where detecting small amounts of calcification is important for the differential diagnosis. As the development of MR imaging continues with faster scan times, finer spatial resolution, the use of paramagnetic contrast agents, and with increased availability and decreased cost, MR imaging may become preferable to CT as the imaging modality of choice for the CNS and orbit.

Painful ophthalmoplegia is an important presenting complaint to emergency departments, ophthalmologists, and neurologists. The etiological differential diagnosis of painful
ophthalmoplegia
is extensive and consists of numerous sinister etiologies including vascular (eg, aneurysm, carotid dissection, carotid-cavernous fistula), neoplasms (eg, primary
intracranial tumors
, local or distant metastases), inflammatory conditions (eg, orbital pseudotumor, sarcoidosis, Tolosa-Hunt syndrome), infectious etiologies (eg, fungal, mycobacterial), and other conditions (eg, microvascular infarcts secondary to diabetes, ophthalmoplegic migraine, giant cell arteritis). A systematic approach to the evaluation of painful
ophthalmoplegia
can lead to prompt recognition of serious disorders that if left untreated, can be associated with significant morbidity or mortality. Inflammatory conditions such as Tolosa-Hunt syndrome and orbital pseudotumor are highly responsive to corticosteroids, but should be diagnoses of exclusion.

The present study was done to observe the ophthalmic manifestations in patients with intracranial tumor. This was a prospective, purposive, consecutive, observational study conducted in patients with radiologically proven
intracranial tumors
in the department of Ophthalmology with collaboration of Department of Neuro-surgery of Bangabandhu Sheikh Mujib Medical University from January 2006 to December 2010. All cases had tissue histopathology confirmation post-operatively. The most common type of intracranial tumor was pituitary adenoma (58.04%), followed by craniopharyngioma (20.53%), posterior fossa tumour (12.50%) [medulloblestoma, ependymoma], meningioma (8.04%) [sphenoidalwing meningioma, petroclavel meningioma, oligodendroglioma] and others (0.89%) [nasopharyngial carcinoma, esthesio - astrocytoma]. Common neuro-ophthalmological findings were visual blur (91.07%), visual field defect (71.42%), optic disc changes (50%), pupillary light reaction defect (48.21%) and colour vision defect (46.42%). The study shows, pituitary adenoma is the most common tumor that impairs the visual pathway structures followed by craniopharyngioma, posterior fossa tumour & meningioma. Furthermore, decreased visual acuity, visual field defect, abnormal optic discs, relative afferent pupillary defect and
ophthalmoplegia
etc. are the common neuro-ophthalmic features that should be carefully examined for early detection of
intracranial tumors
.
