Skull base meningiomas are among the most challenging meningiomas to treat clinically due to their deep location, involvement or encasement of adjacent essential neurovascular structures (such as key arteries, cranial nerves, veins, and venous sinuses), and their often-large size prior to diagnosis.

Journal of Neuro-Oncology, 2005
Metastasis to the skull-base particularly affects patients with carcinoma of the breast and prostate. Clinically, the key feature is progressive ipsilateral involvement of cranial nerves. Five syndromes have been described according to the metastatic site including the orbital, parasellar, middle-fossa, jugular foramen and occipital condyle syndromes ...

Chondrosarcoma at the Skull Base
Annals of Otology, Rhinology & Laryngology, 1981A rare case of chondrosarcoma at the skull base is presented. Computerized tomography scan was very helpful in delineating the exact extent of the tumor. Chondrosarcoma is a slow growing malignant tumor which metastasizes very late. Usually it is radioresistant, but when surgery is not feasible, irradiation treatment is worth a trial.

Head & Neck, 2005
Our purpose was to discuss the optimal treatment and outcomes for patients with skull base chordomas.We reviewed the pertinent literature for this study.Skull base chordomas usually arise in the clivus and are rarely completely resectable. Therefore, most are treated with radiotherapy (RT).

Osteoradionecrosis of the skull base
Journal of Neuro-Oncology, 2020Radiation therapy (RT) is often necessary for the treatment of head and neck cancers. Osteoradionecrosis (ORN) is a rare, but potentially serious complication of RT. RT leads to the destruction of vasculature in radiated tissue causing hypoxia and tissue necrosis.

Otolaryngologic Clinics of North America, 2016
The anatomy of the skull base is complex with multiple neurovascular structures in a small space. Understanding all of the intricate relationships begins with understanding the anatomy of the sphenoid bone. The cavernous sinus contains the carotid artery and some of its branches; cranial nerves III, IV, VI, and V1; and transmits venous blood from ...

Radiologic Clinics of North America, 1998
Skull-base imaging has been a key factor in the advancement of skull-base surgery. The analysis of MR imaging or CT of the skull base emphasizes important landmarks, which are key to surgical planning. Although the definitive diagnosis usually is done by biopsy, the radiologist can limit the list of possibilities of the identity of a skull base lesion.

Otolaryngology–Head and Neck Surgery, 1986
Ten skull‐base neuromas treated at the Otology Group P.C. are presented. Each case is reported in detail. The method by which preoperative diagnosis was made is reviewed. Specific attention is paid to distinguishing these tumors from chemodectomas. Presenting signs and symptoms are enumerated.

Osteomyelitis of the Skull Base
Neurosurgery, 1992Three cases of osteomyelitis of the skull base with associated problems in diagnosis and therapy are discussed. Patients with atypical skull base osteomyelitis are difficult to diagnose as they have no ear abnormalities, but they often develop multiple cranial nerve deficits mimicking symptoms of a posterior fossa mass.
