Brain on FDG PET/CT
Abstract The brain demonstrates substantial physiologic FDG avidity. Malignancy involving the brain, including metastases, lymphoma, and primary gliomas, may be detected either as foci of FDG avidity greater than physiologic…

Abstract The skin and subcutaneous tissues are common sites of inflammatory lesions which must be distinguished from malignancy. Visual inspection of FDG-avid skin lesions is often needed to make this…
Abstract The craniovertebral junction is formed by the occipital bone, atlas, and axis. It is a complex structure and consists of osseous, soft tissue, and nervous system. In this chapter,…
Abstract The spectrum of temporal bone tumors can be considered to be broad and various, ranging from rather frequent and benign lesions, such as meningioma and vestibulocochlearschwannoma, to rare and…
Abstract In the imaging evaluation of hearing loss, the radiologic examination is complementary to the physical examination. The clinical evaluation includes not only an accurate history of the hearing loss…
Abstract This chapter describes primary and secondary bone tumors affecting the skull base and provides important epidemiologic and imaging clues for the differential diagnosis. Except for bone metastases, bone tumors…
Abstract The skull base is made of flat bones that separate the intracranial compartment from the extracranial head and neck. Owing to this unique location, it can be affected both…
Abstract The jugular foramen is a complex skull base foramina containing important neurovascular structures that can be directly evaluated only by CT or MR imaging. Thus it is important to…
Abstract The cerebellopontine angle (CPA) cistern is a subarachnoid space centered within the posterior cranial fossa at the level of the internal auditory canal and bordered medially and laterally by…
Abstract Petrous apex abnormalities are usually incidentally detected on imaging for unrelated symptoms. Their deep location precludes direct clinical examination and easy percutaneous biopsy. Therefore, the radiologist plays a key…
