Objective: The purpose of this study was to ascertain the use of ultrasound in speculating the severity of disease by correlating ultrasound imaging features with platelet count. If ultrasound serves as an important supplementary to the clinical and laboratory profile in diagnosing dengue fever was also studied. Materials and methods: 102 patients were studied retrospectively who were serologically positive for dengue fever between early September 2015 and 2016 to late october 2015 and 2016.These patients were sent for ultrasound examination of the abdomen and thorax and than imaging features were studied. Results: Of the 102 seropositive dengue patients, 65(63.72%) showed GB Wall thickening, 35(34.31%) showed ascitis, 70 (68.6%) showed bilateral pleural effusion,40 (39.21%) showed hepatomegaly, 56 (54.91%)showed splenomegaly and in 11 (10.78%) patients USG study was found to be normal. In this study, one patient showed honey comb appearance of GB wall with GB wall measuring 10mm. Patients with platelet count of less than 40,000, 100% showed GB wall thickening and pleural effusion and 50% showed ascitis. In patients with platelet count between 40,000 – 80,000, pleural effusion was more common than GB wall thickening. Whearas patients with platelet count of >1.5 lac, still 11 patients were found to have persistent GB wall thickening. Conclusion: Sonographic imaging features of GB wall thickening, pleural effusion, ascitis, hepatomegaly, splenomegaly favoured the diagnosis of dengue fever especially during an epidemic in the postmonsoon period and the patient presenting clinically with fever and accompyning symptoms. Reduced platelet count showed a direct relationship to abnormal ultrasound features.
