Occipital Osteodiastasis.

Occipital osteodiastasis (OOD) is a prominent traumatic lesion in neonates born by breech, during delivery of after coming head. The lesion consists of traumatic separation of the cartilaginous joint between the squamous and lateral portion of the occipital bone resulting in a posterior fossa subdural haemorrhage associated with laceration of the cerebellum. We report a term female baby with OOD born by breeach extraction with X-ray skull showing separation of squamous and lateral portion of occipital bone and NCCT brain revealing large extra axial bleed in the right temporo-parieto-occiptal region.

Large choroid plexus teratoma: A rare cause of congenital hydrocephalus.

Teratomas form the most common type of congenital brain tumors, frequently presenting as stillbirth. The largest neonatal series of intracranial teratomas reported a 12% survival rate. Although the first teratoma of the lateral ventricle was reported in 1961 by Maier, neonatal intracranial teratoma of the lateral ventricle is an extremely rare entity. We report here a large intracranial poorly differentiated teratoma arising from choroid plexus of lateral ventricle. This typically presented at birth with a large congenital hydrocephalus.
