Pituitary adenomas are generally considered benign tumors; however, a subset of these tumors displays aggressive behavior and are not easily cured. The protocol for nonsurgical treatment of aggressive pituitary lesions…
This article discusses contemporary use of external beam radiotherapy and stereotactic radiosurgery for pituitary adenoma patients. Specific techniques are discussed. In addition, indications and outcomes, including complications, are detailed. •…
The endoscopic transsphenoidal approach to the sella turcica has been developed and refined for the treatment of pituitary lesions. Studies comparing endoscopic transsphenoidal surgery with the traditional microscopic transsphenoidal technique…
Clinically nonfunctioning pituitary adenomas range from those causing significant hypothalamic/pituitary dysfunction and visual field compromise to those being completely asymptomatic, detected either at autopsy or as incidental findings on imaging…
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…
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…
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…
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…
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 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…
