case_images: At the age of 6 months, the swelling measured 8 cm (Figure 1).
case_images: Brain MRI: sagittal section: an occipital bone defect giving birth to a bag of meningeal envelopes containing liquid in hyposignal T1 (A) and hypersignal T2 (B).

case_images: The MRI revealed an occipital bony defect with a neck measuring 25 x 25 mm, giving rise to a sac of meningeal membranes containing fluid with low signal intensity on T1 and high signal intensity on T2, devoid of brain tissue or ventricles, thus ruling out the diagnosis of meningoencephalocele and meningoencephalocystocele measuring 86 x 77 mm (Figure 2).
case_images: Increase in size of the occipital swelling with the presence of yellowish fluid.

case_images: fig3-2333794X231204498
case_images: A decision for surgical intervention was made, but another 2-month delay, again due to family reasons, led to a change in the clinical appearance of the swelling, which increased in size and exhibited a yellowish fluid (Figure 3).
case_images: Brain MRI: (A) sagittal section T1, (B) Axial section T2: an occipital bone defect giving birth to a bag of meningeal envelopes containing liquid in hyposignal T1 and hypersignal T2, (C) Brain MRI: Sagittal section with injection : Presence of an enhanced portion after injection of PDC related to thickened meninges and vascular structures in favor of infectious neo-angiogenesis.
