The imploding antrum: An unusual case of nontraumatic painless enophthalmos.

The imploding antrum or silent sinus syndrome is a rare phenomenon that presents with spontaneous painless enophthalmos and hypoglobus. It occurs due to ipsilateral maxillary antral atelectasis secondary to asymptomatic obstructive chronic sinus mucosal disease. Ophthalmologists, otorhinolaryngologists, and radiologists must be aware of this entity.

Duplication of the pituitary gland - plus syndrome.

Duplication of the pituitary gland (DPG) is a very rare developmental anomaly that is often associated with other anomalies - the DPG-plus syndrome and occurs due to splitting of the rostral notochord and prechordal plate during blastogenesis. DPG with the constellation of associated anomalies as in our patient has not been reported previously. This article illustrates the importance of imaging the brain in all patients with obvious midline facial anomalies and the complementary role of MRI and CT in such cases.
