Case contributed by Ammar Haouimi
Diagnosis almost certain

Presentation

Febrile seizures. Rule out meningitis.

Patient Data

Age: 4 years

Normal posterior cerebral fossa and cerebral hemispheres with no abnormal parenchymal or leptomeningeal enhancement. Normal size of the ventricular system, cavum septi pellucidi.

Note the complete absence of the sagittal suture with a normal head configuration.

Case Discussion

The absence of the sagittal suture should not be interpreted as premature fusion or scaphocephaly. Usually, this can be considered as an isolated anomaly without skull deformation.
