Cranial MR imaging of osteopetrosis.

Background And Purpose: The purpose of this study was to describe the cranial MR imaging manifestations of osteopetrosis. These features have not previously been reported in the literature.

Methods: Cranial MR studies, obtained with a uniform imaging protocol, were reviewed in 47 patients with osteopetrosis.

Endobronchial cockroach: an unusual foreign body aspiration.

Foreign-body aspiration is a frequent and potentially lethal occurrence in children. It is associated with a variety of symptoms including choking, coughing, and wheezing. These symptoms differ in severity and are sometimes absent, and chest radiograph findings are often nonspecific.

Intracranial placement of a nasotracheal tube after facial fracture: a rare complication.

Extensive facial trauma is often associated with fractures to the skull base, cribriform plate, and sphenoid sinus. Attempted intubation of patients with facial trauma may result in intracranial penetration and placement of nasogastric or nasotracheal tubes into the brain. Such a complication carries significant morbidity and mortality.
