The anterior fontanel encephalocoele is a very rare entity encountered in the clinical practice. When the size of the encephalocoele is larger than the head itself, it is termed as giant encephalocoele.
The case discussed by Behera[1] shows the findings suitable to be called a giant encephalocoele, although the location as anterior fontanel encephalocoele is not justifiable through the images and the clinical pictures given with the case report.
The encephalocoele can be termed to be arising from anterior fontanel encephalocoele if it is arising from the center of anterior fontanel and not any attachment to the bone.[2] The reasons that the case discussed cannot be anterior fontanel encephalocoele are
- The defect is visible in the right parietal bone wall of the anterior fontanel
- The swelling is not in the midline and is over the right edge of the fontanel.
- The defect is not anywhere near the frontal bones, so cannot be termed as “interfrontal” either as interfrontal encephalocoele originate between nasion and anterior fontanel.[3]
So, we suggest that, rather than calling this case a case of interfrontal anterior fontanel giant encephalocoele, it should be termed as right medial parietal giant encephalocoele.
A schematic diagram of the frontal–parietal encephalocoele is attached herewith for further clarification [Figure 1].
