Aims and objectives
Intracranial metastases represent the most central common nervous system neoplasm [1] and have a poor prognosis [2].
Most of them are solitary parenchymal lesions (Fig.
1,
2) (80 % located in the cerebral hemispheres,
15 % in the cerebellum,
3 % in the basal ganglia,
while the brainstem is a rare localization).
[3] Uncommon localisations for intracranial metastases are: leptomeningeal (found in only 5 % of patients with systemic neoplasms),
ventricular (accounting for 1-5 % of cerebral metastases,
most commonly in the lateral ventricle choroid plexus) [4],
orbital (extremely uncommon,
usually extraconal) [5],
paranasal sinuses (extremely rare,
generally in the maxillary sinus ) [6],
pituitary gland (1 % of pituitary tumors,
usually located in the posterior lobe) [4].
The median age of patients diagnosed with secondary brain lesions is reported between 57 and 63 [7].
These given,
the aim of our study is to present the intracranial localisations of metastases among patients with various neoplasms.
