Abstract

Purpose

To evaluate the role of susceptibility-weighted imaging (SWI) in patients with idiopathic intracranial hypertension (IIH).

Materials and methods

A prospective study was done on 55 patients with IIH who underwent SWI of the brain. The images were evaluated by two independent readers for cerebral microbleeds (CMBs) and the interobserver agreement between both readers was calculated. The graphic rating scale (GRS) for headache was calculated.

Results

CMBs were found in 16 (29%) of patients with IIH for both readers with excellent interobserver agreement (K = 0.8, p = 0.001). There was excellent interobserver agreement for location (K = 0.8, p = 0.001) and side of CMBs (K = 0.8, p = 0.001). There was good interobserver agreement for size of CMBs (K = 0.75, p = 0.002) and number (K = 0.6, p = 0.006). The mean GRS for headache in patients with CMBs (5.61 ± 1.3) was significantly higher (p = 0.02) than that of patients without CMBs (4.9 ± 0.8).

Conclusion

We concluded that SWI can detect CMBs in patients with IIH especially in  patients with higher GRS for headache.
