title: [Optochiasmatic tuberculoma and MRI. 2 cases].
abstract: Two cases are reported of optochiasmatic tuberculoma, an exceptional complication difficult to diagnose in the absence of any tuberculous context. Although diagnosis of the optochiasmatic occupying process is simple by scan or NMR imaging, it is generally difficult to identify the chiasma in a process of this type. It is therefore impossible to recognize the two forms of these tuberculomas: intra- and peri-chiasmatic histologic types, and yet these have an incidence on therapy and prognosis. Surgical exploration is justified when the diagnosis remains in doubt or when the functional prognosis is implicated.
