Summary
A midline tuberculous abscess caused raised intracranial pressure by compressing the superior sagittal sinus. This rare cause of elevated intracranial pressure highlights unusual intracranial tumour presentations.
Area of Science:
- Neurology
- Neurosurgery
- Infectious Disease
Background:
- Raised intracranial pressure (ICP) can result from intracranial tumours obstructing venous sinuses.
- Midline occipital tumours uncommonly cause ICP elevation via non-thrombotic compression of the superior sagittal sinus.
Observation:
- A case of elevated ICP is presented.
- The cause was a midline tuberculous abscess.
Findings:
- The tuberculous abscess non-thrombotically obstructed the superior sagittal sinus.
- This obstruction led to secondary raised intracranial pressure.
Implications:
- Tuberculous abscesses should be considered in the differential diagnosis of midline occipital masses causing ICP elevation.
- This case expands the understanding of non-thrombotic venous sinus compression as a mechanism for raised ICP.
