Questions

In regards to petrous temporal bone fractures, which is FALSE? 

In transverse fractures of the petrous temporal bone, which cranial nerve is most likely injured?

Which connective tissue disease is associated with lymphocytic interstitial pneumonitis (LIP)?

According to Barrow classification, what is the most common type of caroticocavernous fistulae?

A CT report for facial trauma contains the following findings: "There is a mildly comminuted fracture involving the left frontal process of the maxilla and left nasal bone. Fracture lines in this region extend from the pyriform aperture across the medial maxillary buttress to the left inferior orbital rim, sparing the infraorbital canal. However, minimally displaced fractures involve the medial third of the orbital floor, internal orbital buttress, and the lamina papyracea. There is less than 0.5 mm outward herniation of extraconal fat into the ethmoid labyrinth. One of the fracture lines extends anteriorly to the frontomaxillary suture, liberating a minimally displaced fragment of bone containing the lacrimal fossa, which appears intact. The left lateral orbital wall is intact. There is a fracture of the medial wall of the maxillary sinus but not the lateral wall."

What classification best summarizes the most significant injuries?

Which of these structures is NOT removed in a radical neck dissection?

Which of these structures may be removed during a selective neck dissection?

Which of the following MRI sequences is most likely to best allow the identification of individual cranial nerves within the cavernous sinuses?

Which of the following imaging findings is most suggestive of cavernous sinus thrombosis on CT venography (CTV) in an intubated patient?

An MRI of a patient with left facial numbness and ophthalmoplegia shows a T2 intermediate signal intensity mass in the left cavernous sinus which exhibits homogeneous enhancement and extends into Meckel’s cave and the orbital apex. The flow void of the left internal carotid artery is mildly narrowed. CT shows mild thickening and sclerosis of the lateral wall of the left sphenoid sinus.

Which connective tissues disease is commonly associated with nonspecific interstitial pneumonia (NSIP) pattern on imaging?

Which of these structures do not typically drain into level IA nodes?

During ultrasound of the neck, the relationship of which two structures is a useful surrogate for the margin between level III and level IV?
