OBJECTIVE
We intended to assess the clinicopathological features and treatment outcome in patients of intracranial atypical teratoid rhabdoid tumor (AT/RT), a rare malignant tumor of the brain.
METHODS
Medical records were reviewed and clinical data collected on AT/RT in a 6-year period (2006-2012).
A Malignant rhabdoid tumor (MRT) arising in the right temporoparietal lobe of a 9-year-old boy is described along with the results of an immunohistochemical study. The patient initially sought medical attention for a ptosis and right sided headache. The child underwent a subtotal resection of the
Rhabdoid tumors of the central nervous system are rare malignancies. Primary central nervous system atypical teratoid/rhabdoid tumors (ATT/RhTs) mostly occur during early childhood and are almost invariably fatal. These tumors show similar histological and radiological features to primitive
Atypical teratoid/rhabdoid tumor (AT/RT) is a rare, highly malignant tumor of the central nervous system (CNS) that typically occurs during infancy. These tumors exhibit morphologic heterogeneity and differentiate along multiple lineages, thus posing a diagnostic challenge. Here, we present two
A 4-year-old boy presented with anorexia, headache, and poor spirits was found to have tumors in posterior fossa and suprasellar region which enclosed by CT scan of brain. Bilateral suboccipital craniotomy was performed by neurosurgeon. The pathological report revealed the tumor was malignant
Malignant rhabdoid tumor (MRT), described for the first time in 1978 in the kidney, has rarely been reported in other organs including the brain and has involved adults in only 3 cases. We described a case of MRT in a 32-year-old woman who presented with severe headache, nausea and sudden onset of
Here we present the case of a 60-year-old woman with a rare sellar region atypical teratoid/rhabdoid tumor (AT/RT), complicated by lung metastasis and treated with neurosurgery, radiotherapy, and chemotherapy. The patient had recurrent headache associated with left cavernous sinus syndrome after a
BACKGROUND
Atypical teratoid/rhabdoid tumors (ATRT) are uncommon malignancies of the central nervous system and often difficult to distinguish radiographically and pathologically from other common tumors. In this report, we present the first case of sellar ATRT presenting with subarachnoid (SAH) and
Atypical teratoid/rhabdoid tumors (AT/RT) of the central nervous system are rare and extremely aggressive malignancies of early childhood. We report a case of AT/RT in an adult patient. A 30-year-old woman presented with headache, vomiting and ataxia during the second trimester of pregnancy.
Atypical teratoid/rhabdoid tumor (AT/RT) is a rare, highly malignant, true rhabdoid tumor in the central nervous system predominantly presenting in young children.AT/RT typically shows rhabdoid cells which can also be seen in other tumors, but it is differentiated from other tumors by the specific
Rhabdoid tumors of the central nervous system are uncommon, aggressive childhood malignancies. The 13 described adult cases comprise both primary CNS tumors and malignant transformation of previously existing gliomas, meningiomas, and astrocytomas. Central nervous system rhabdoid lesions of adults
Background: Atypical teratoid rhabdoid tumor (ATRT) is a rare, highly malignant central nervous system neoplasm classified as an embryonal grade IV neoplasm by the World Health Organization. ATRT generally occurs in children younger than
This paper presents the case of an eight-year-old girl who presented with headache and vomiting and was found to harbor a right fronto-temporo-parietal, partially cystic and centrally solid tumor that measured 11 x 8 x 7 cm. This vascular tumor was gross totally removed. The initial histopathologic
Rhabdoid tumors of the brain are rare with an invariable dismal prognosis despite treatment. This is the case of a 3 year old boy who presented lethargy, somnolence, nausea, vomiting, and headaches one week prior to hospitalization. A posterior fossa tumor with hydrocephalus was noted on a head
Teratoid/rhabdoid tumor is a recently introduced infantile brain neoplasm of uncertain origin clinically characterized by a most aggressive course. We describe the case of a 2-year-old boy and a 7-year-old girl, the former presenting with central fever and hemiparesis, while vomiting and headache
