Abstract

Background

The most frequent clinical presentation of occipital or visual tract lesion is hemianopsia or quadrantanopsia. However, damage to the primary or secondary visual cortex can also manifest as visual hallucinations (photopsiae or complex phenomena). We report visual and somatosensory phenomena following cerebral venous infarction based on a study of a patient with a history of recent head injury.

Case presentation

We report a 61-year-old man with a history of recent head injury presented with a headache of two weeks duration. He was complaining of transient visual abnormalities, which he described as impaired ability to recognize faces, dark spots moving in the visual field and distorted contours of an objects. Clinical examination showed a balance disorder with no evidence of visual deficit. During further observation the patient started to experience more complex visual and sensory phenomena of: waving of the ceiling, clouds that he could form and feel, he had an impression of incorrect sizes of given objects, he could see a nonexistent pack of cigarettes and the character from the arcade game Pac-Man “eating” an existing drip stand.

Conclusions

The patient mentioned above possessing simple and complex visual and somatosensory hallucinations and illusions in the course of venous stroke. A possible mechanism involves irritation of cortical centers responsible for visual processing.
