[Difficulties in the diagnosis of brain tumors]

In 27 patients brain tumors were misdiagnosed for several years. Most mistakes were due to the incomplete analysis of the patients' complaints, anamnesis and peculiarities of the disease development. Most difficult were identifying the leading neurologic deficit, detecting the adjacent and remote signs. Using full sequence of both simple and sophisticated diagnostic techniques (PET, angiography, CT etc.) one can sharply reduce the incidence of diagnostic errors.
