MRI Brain Lesions in Eclampsia: A Series of 50 Cases Admitted to HDU of a Tertiary Care Hospital
,
Abstract
Objective: To correlate the Magnetic Resonance Imaging findings and clinical presentation in patients of eclampsia.
Materials and methods: This one year prospective study was conducted in the HDU of Department of Obstetrics and Gynecology, PT.B.D.Sharma, PGIMS, Rohtak .A total of 50 women with eclampsia (both antepartum and postpartum) were divided into two groups: a) study group patients with abnormal MRI
b) control group: b) control group: patients with normal MRI.Comparison was done using chi-square test and unpaired student ‘t’ test.
Results: MRI revealed abnormal findings in 24% of women, commonest diagnosis being CVT without infarct (10%) followed by infarct (8%), PRES (4%) and HLE (2%).Totally 66% (n = 33) of the women presented with postpartum eclampsia while 34% (n = 17) had antepartum eclampsia.96%(n = 48) were unbooked cases. Unconsciousness, altered sensorium, headache, blurring of vision, seizures, GCS < 3 correlated well with MRI findings (p = 0.000, p = 0.027, p = 0.001, p = 0.007, p = 0.005, p = 0.000 respectively) whereas fundoscopic changes did not (p = 0.520). The mean uric acid and serum creatinine levels was higher (0.41 ± 0.11 mmol/ L vs 0.26 ± 0.10 mmol/ L and 80 ± 18 µmol/ L vs
71 ± 9 µmol/ L) in the study group and this was statistically significant (p = 0.003, p = 0.04 respectively).There was no statistically significant difference between blood pressure values of cases with or without MR imaging evidence of brain lesions. There was no maternal mortality among 50 cases. The sensitivity, specificity, positive predictive value and negative predictive value of neurological findings for abnormal MRI in patients with eclampsia was found to be 91.7%, 73.7%, 52.4%, 96.6% respectively.
Conclusion: Unconsciousness, altered sensorium, headache, blurring of vision,seizures, GCS < 3, elevated uric acid and serum creatinine levels in the follow-up of pregnant patients with preeclampsia/eclampsia should be a warning for possible brain lesions whereas booking status, mean BP, fundoscopy, platelet, hemoglobin, liver enzymes were not significantly associated with positive MRI findings in patients of eclampsia.
