Approximately 60% of patients with brain metastases have subacute symptoms. Symptoms are usually related to the location of the tumor. About 85% of the lesions are in the cerebrum, 15% are in the cerebellum, and 5% are in the brainstem. Morning headache with nausea and vomiting together with papilledema are suggestive of intracranial hypertension. Features such as headache, nuchal rigidity and photophobia indicate meninges involvement. The timing of the onset of these symptoms is subacute

In these cases, identifying the cancer site of origin is non-feasible by visual examination of magnetic resonance (MR) images. Recently, radiomics has been proposed to analyze differences among classes of visually imperceptible imaging characteristics.
