The clinical characteristics, treatment and prognosis differences between occipital brain tumors with venous flow obstruction and occipital brain tumors without venous flow obstruction

Patients with occipital tumors may present with symptoms similar to PTC secondary to venous drainage obstruction. Therefore, it is important in patients with PTC symptoms and occipital tumor to preform Magnetic-Resonance-Venography or Computed-Tomography-Venography as well. Most of the patients needed surgical intervention in addition to medical treatment in order to preserve visual functions. Probably the early treatment to this group brought to good visual prognosis that was not different from the group without venous drainage obstruction. Therefore, early diagnosis and prompt multi-disciplinary treatment may lead to better results in cases of occipital tumors with venous drainage obstruction.
