ABSTRACT
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. This article illustrates the typical presentation in a 17‑year‑old male with unilateral ptosis and a deep superior sulcus, and characteristic imaging findings of ipsilateral increased orbital volume and depression of the orbital floor, maxillary sinus opacification and atelectasis with retraction of the posterolateral and medial walls, lateralization of the uncinate process, and obstruction of the ostiomeatal unit. This is probably the first time that the syndrome is being reported in such a young person. The pathogenesis, differential diagnosis, and treatment modalities of this entity are also reviewed.
ABSTRACT
Tuberous sclerosis is a genetic disease with autosomal dominant inheritance, associated with hamartomas in several organs and various skin findings. A case of a ten year old boy is presented here to highlight the multisystem involvement in tuberous sclerosis. The child had seizures, facial papular naevi and peri-ungual fibromas. MRI revealed cortical tubers, white matter lesions and subependymal nodules. Orbital ultrasound showed retinal hamartoma on the left side. Ultrasound of the abdomen revealed a soft tissue mass at the upper pole of left kidney with a small cyst in right kidney.
