Sphenoclival Intraosseous Lipoma: A Typical Lesion at an Atypical Location.

In this report, we present the case of a rare tumor in the sphenoclival region and discuss the potential pitfalls in its diagnosis and management. Intraosseous lipoma is a rare benign tumor, mostly accounting for 0.1% of all bone tumors.

Chorangiopagus parasiticus twins.

Chorangiopagus parasiticus twins (CAPP) occur due to asymmetric abnormality of monozygous, twinning. It is the commonest form of asymmetric twinning, occurring in 1% of monozygous twins. The asymmetric twin survives by parasitizing the more normally developed co-twin by connecting with the chorionic circulation, hence, chorangiopagus parasiticus.
