Demographics:
44 years old, Female
Indication:
Headache, vertigo
Findings
- Empty, expanded sella
- Narrowing of the bilateral distal transverse sinuses with irregular contour and linear intraluminal filling defects
- Expansion of the left Meckel's cave
- Low-lying cerebellar tonsils without peg-like morphology or significant crowding at the foramen magnum
- Mild dilation and tortuosity of the bilateral intraorbital optic nerve sheaths with mild flattening along the posterior sclera bilaterally
- No evidence of acute infarct, hemorrhage, mass effect, or hydrocephalus
Diagnosis
Idiopathic intracranial hypertension (IIH)
Sample Report
No evidence of acute intracranial abnormality.
Constellation of findings including bilateral posterior scleral flattening, tortuous intraorbital optic nerves, empty expanded sella, bilateral distal transverse sinus stenosis, and low-lying cerebellar tonsils is typical for idiopathic intracranial hypertension (IIH). Recommend correlation with CSF pressure analysis.
Irregularity of the transverse sinuses with linear intraluminal fillings defects, which could be the result of remote thrombus and/or webs.
