[Multiple non-neoplastic lesions in computerized cranial tomography].
Multiple intracranial lesions observed in the computerized tomography ever cause worry due to the possibility of neoplastic etiology, although granulomatous diseases (parasitic or not) and vascular diseases can produce this type of lesions. Five patients with clinical picture that suggested expansive intracranial masses and that had multiple lesions in the computerized tomography that suggested neoplastic diseases are presented. In all patients the clinical evolution and/or other complementary diagnostic tests showed the non neoplastic etiology of the lesions. In three patients the lesions were due to parasitic diseases (intracranial tuberculomas in one case and neurocysticercosis in two cases) and in the other two cases the lesions were due to vascular disturbs (cerebral infarcts). The knowledge of the several diseases that can cause multiple intracranial lesions as seen in the computerized tomography allows to direct the etiologic diagnostic that is essential to introduce the correct treatment avoiding irradiation of non neoplastic lesions and unnecessary surgical procedures. In our country, granulomatous parasitic diseases, mainly neurocysticercosis, tuberculosis and fungal diseases must be considered in the differential diagnosis of multiple intracranial lesions observed in the computerized tomography, together with cerebral infarcts and neoplasms.
