Because solitary fibrous tumor (SFT) and hemangiopericytoma (HPC) contain identical genetic abnormalities, the World Health Organization coined the term SFT/HPC to describe these lesions. Here, we present a rare case of SFT/HPC in a 40-year-old man with massive repeated intracranial hemorrhage (ICH) in right medial temporal lobe. ICHs from a SFT/HPC were repeatedly misdiagnosed as hypertensive ICH by several departments and hospitals over approximately eight months, and the patient underwent inappropriate treatments. The amount of repeated ICH accompanying the tumor has increased significantly compared to the first ICH, which may suggest rapid tumor growth. To avoid misdiagnosis and inappropriate treatment, surgeons should carefully examine all past and current patient-related radiological images and medical records before considering surgery.

Optic neuritis (ON) may rarely mimic optic nerve tumor, index of suspicion should be kept high. A 34-year-old woman presented to a major academic institute with a history of right-sided ocular pain and progressive visual loss in the same eye. Her magnetic resonance imaging showed markedly thickened optic nerve; her workup for inflammatory pathology was negative; she was diagnosed as a case of optic nerve tumor and was planned for surgery. Patient for second opinion came to a tertiary care institute where on proper history taking and evaluation she was diagnosed and treated on the lines of ON and she improved. The diagnosis of ON is a clinical one, it may mimic optic nerve tumor in rare cases.
