What our notes say
- The resultant cranial abnormalities include ventriculomegaly, lemon sign (due to flattened frontal bones), banana sign (due to effacement of the cisterna magna), and head measurements that are small for gestational age. (CNS PATHOLOGY — Past Paper Questions & Answers)
- With the lemon sign, the frontal bones are flattened (almost concave) so that the anterior skull is not as rounded. (CNS PATHOLOGY — Past Paper Questions & Answers)
- Infection can spread to adjacent bone (e.g., frontal bone osteomyelitis — Pott's puffy tumour). (Head & Neck Pathology MCQs: Oral, Ear, Throat & Gland Tumors)
- Location: Underneath the frontal bone, most anterior part of the cerebrum. (Clinical Anatomy of the Cerebral Cortex)
