Neuroradiology, 1978
A systematic study of the structures of the base of the skull was performed with CT. The findings in 141 pathological cases are described. The value and some limitations of this kind of investigation are described and discussed. A comparison with conventional tomography is made.

Intracranial chondrosarcoma are rare tumours, accounting for approximately one in 1000 intracranial neoplasms. Although more common in the axial or appendicular skeleton, intracranial tumours present a challenging surgical and oncological problem. Chondrosarcoma have a predilection for the skull base and although commonly slow growing, Grade II and III

Ganglioneuroma of the Base of the Skull
Journal of Craniofacial Surgery, 2011Ganglioneuromas are rare benign tumors originating from the ganglion cells of the sympathetic and parasympathetic nervous system. Ganglioneuromas in the base of skull are extremely rare. In this article, we describe a case of primary ganglioneuroma below the foramen ovale observed in a 38-year-old man. The lesion was asymptomatic. The patient underwent

Osteomyelitis of the base of the skull
The Laryngoscope, 1986AbstractInfection in the marrow of the temporal, occipital, and sphenoid bones is an uncommon, but increasing occurrence. It is usually secondary to infections beginning in the external auditory canal and is caused almost uniformly by the gram negative Pseudomonas aeruginosa bacteria.

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.

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 ...

Skull base hemangiopericytomas
Acta Neurologica Belgica, 2021To retrospectively evaluate the clinical outcome of six patients with skull base hemangiopericytomas (HPCs) and that of a cohort of 37 similar patients identified by a systematic review of the literature.The series constitutes of three men and three women with newly diagnosed skull base HPC who underwent multimodal treatment including surgery, external

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.

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).

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.
