Imaging the Pituitary and Parasellar Region
Magnetic resonance imaging is the fundamental imaging tool for the evaluation of tumors and other lesions of the pituitary gland and infundibulum. Abnormalities may arise within the pituitary itself, from…
Radiotherapy for Malignant Tumors of the Skull Base
Malignant tumors of the skull base are a fascinating group of tumors arising via disparate causes leading often to similar presentations. This article explores radiotherapy techniques applied to this group…
Craniofacial Reconstruction Following Oncologic Resection
The ability to reliably reconstruct complex and sizable wounds has decreased the morbidity of skull base surgery substantially, preventing major complications and allowing treatment of tumors previously considered inoperable. Addressing…
Temporal Bone Malignancies
Primary temporal bone tumors are rare. Suspicious lesions of the ear canal should be biopsied for diagnosis. Surgical resection to achieve negative margins is the mainstay of treatment. Small tumors…
Head and Neck Sarcomas
Sarcomas of the head, neck, and skull base represent a heterogeneous group of tumors with distinct prognostic features. There have been significant improvements in characterizing these sarcomas using traditional morphologic…
Esthesioneuroblastoma
Esthesioneuroblastoma is a rare malignant neoplasm in the olfactory region of the nasal cavity and anterior skull base. Diagnosis and staging require anatomic imaging and careful pathologic assessment. Standard treatment…
Skull Base Chondrosarcoma
Chondrosarcomas are indolent but invasive chondroid malignancies that can form in the skull base. Standard management of chondrosarcoma involves surgical resection and adjuvant radiation therapy. This review evaluates evidence from…
Sinonasal Carcinomas
Sinonasal carcinomas are uncommon neoplasms accounting for approximately 3% to 5% of all upper respiratory tract malignancies. Sinonasal malignancies in most cases do not cause early symptoms and present in…
Skull Base Chordomas
Chordomas of the skull base are one of the rarest intracranial malignancies that arise from ectopic remnants of embryonal notochod. The proximity of many chordomas to neurovascular structures makes gross…
Minimally Invasive Approaches to the Anterior Skull Base
The use of minimally invasive approaches to the anterior skull base is a valuable tool to improving the treatment in patients with aggressive anterior skull base neoplasms. This article discusses…
