A Study of Seizures in Children and their Correlation with Various Types of Ring Lesions found on Cranial Computed Tomography

A ring enhancing lesion in brain imaging is a common feature in the Indian subcontinent. The size, shape, wall thickness of ring-enhancing lesions and extent of surrounding edema, and importantly, clinical history and age of the patient may help to distinguish the etiology.

To study the clinical profile of children having seizures and their correlation with ring lesions including their type, number and size.

The study was conducted at the Department of Paediatrics, Muzaffarnagar Medical College & Hospital, Muzaffarnagar. A total of 117 children (1–18 yrs), presenting with different types of seizures from April 2014 to June 2015 were taken up for the study. Detailed clinical history of seizures was taken, and general and systemic examination was done. All patients underwent hematological & biochemical investigations, chest xray, Montoux test and cranial computed tomography.

There was male predominance in the study(51.15%). Complex partial seizures was the most common type (53.27%). Majority of the lesions were single(37.38%) with the parietal lobe being the commonest site of occurrence(33.64%). The commonest etiology was neurocysticercosis (51.41%) followed by tuberculoma(6.55%).

We can conclude that the most common cause of ring enhancing lesion on cranial CT in 1–18 yrs of children is neurocycsticercosis followed by tuberculoma.
