Introduction Most often, ganglioneuromas affect older pediatric and adult patients. They are typically slow growing tumors that remain clinically silent until they become large enough to cause symptoms by compression of adjacent structures. Case We report a case of a 22-year-old Hispanic gravida 2
A 23-year-old male known to have an asymptomatic mediastinal mass for four years was admitted due to progressive pitting edema of his arms and legs lasting for one week. The edema subsided prior to surgical extirpation of the left paraspinal mass. Initially recognized radiologically as a
Adrenal ganglioneuroma (AGN) is an extremely rare, benign tumor that originates from the neural crest tissue of the sympathetic nervous system. The majority of cases are detected incidentally, since the disease often lacks clear clinical manifestations or is asymptomatic. In addition, AGN is often
We report a case of gangliocytoma at a cortical and subcortical area in the right parietal lobe. The patient had a generalized seizure at 11 years of age. The MRI shows an ill-demarcated high intensity area in T2 weighted images including an enhancing tumor of 10 mm in diameter. At first, the tumor
Recent reports have suggested that cyst formation accompanying astrocytomas in the central nervous system (CNS) is due to an edematous process caused by blood-brain barrier (BBB) disruption and not a result of necrosis. This study is performed to investigate whether the hypothesis of cyst formation
Our objective was to review current literature pertaining to prenatal ultrasonography of various fetal intracranial neoplastic and non-neoplastic tumors. To this goal, all manuscripts published in the English language regarding this topic obtained from a MEDLINE search from 1966 through January 1998
OBJECTIVE
Intramedullary spinal cord tumors can displace the surrounding neural tissue, causing enlargement and distortion of the normal cord anatomy. Resection requires a midline myelotomy to avoid injury to the posterior columns. Locating the midline for myelotomy is often difficult because of the
Ultrasonic examinations of 3000 pregnant women revealed congenital developmental defects in 22 (0.7%) fetuses: in 4 cases tumors of various sites were detected and in 2 cases the tumors were found in one of the twins. Pathologic and histologic examinations carried out after delivery revealed a
In the publication by the World Health Organization of the histological classification of central nervous system tumors in 1993, several new tumor types were added, including pleomorphic xanthoastrocytoma (PXA), dysembryo-plastic neuroepithelial tumor (DNT), and desmoplastic infantile ganglioglioma
Compound tumors of the adrenal medulla, characterized by a mixture of pheochromocytoma and ganglioneuroma, are rare, only 12 cases having been reported in the literature. We present the case of a 66-year-old woman with a left-sided incidentally discovered adrenal mass that was subsequently shown to
Glial neoplasms that are peripherally located and involve the cortical gray matter are noteworthy because of their predilection to serve as a seizure locus, their amenability to surgical resection, their generally favorable prognosis, and their characteristic imaging features, which facilitate
