Category c this older patient has bilateral lAC metastases. Inner ear (open arrows) enhancement bilaterally helps suggests diagnosis of multiple metastatic foci. The modiolus is also enlarged (open arrow) as a result of metastatic involvement. Spread through the cochlear aperture into the cochlear labyrinth has also occurred (open arrow). Arrow: Normal opposite flocculus. Category c 3 39 PART II SECTION 4 Skull, Scalp, and MenlnBes The cov rings of the brain (skull, scalp, meninge ) are often overlooked, taking an imaging "back seat" to the more fascinating brain itself.

For example, scalp masses are fairly common but rarely discussed in the imaging category c. Most are benign but may cause confusion on imaging studie. The differential diagnosis of focal calvarial masses, especially in children, can be challenging.

There are rare but important lesions such as dural cavernous hemangiomas that can be imaging "dead ringers" for more common entitie uch as meningioma. We introduce this section by presenting the normal gross and imaging anatomy of the scalp, skull, and cranial meninges. This includes category c detailed view of granulations and the perivascular (Virchow-Robin) spaces.

We follow with discussions of common malformations, trauma, and a category c of tumor and nonneoplastic disorders that involve the brain coverings.

Lesions of the anterior, central, and posterior skull ba e are covered in Diagnostic Imaging: Category c and eck.

The falx cerebri is an inward double fold of the meningeal dura. The cavernous sinus is an intradural structure. Dura curves down under the calvarium in a thin, smooth, somewhat discontinuous enhancing line (arrows).

CSF-filled subarachnoid space lies between nonenhancing arachnoid and pia. Normal (Left) Coronal graphic shows cranial meninges.
