Focal Electroencephalography Rhythm Asymmetry due to Focal Skull Fibrous Dysplasia
نویسنده
چکیده
An unusual pervasive and persistent asymmetry in background rhythm was found on surface electroencephalography (EEG) recordings in a 22 year old with new onset of generalized seizure activity. Radiographic correlation with computed tomography, positron emission tomography and bone scan imaging uncovered that the higher amplitude left frontal-parietal background activity was related to a circumscribed area of left frontal-parietal fibrous dysplasia affecting the skull. This case report emphasizes that the presumed higher electrical conductance of fibrous dysplasia lead to a greater transparency of normal background rhythms, and must be taken into account as a form of breach rhythm for accurate EEG interpretation.

Fibro-Osseous lesions are numerous and heterogeneous group of tumors of the jaws which pose difficulties on classification, diagnosis and treatment. The present study was undertaken to evaluate fibrous dysplasia and the diagnostic value of histologic examination for its workup. Fifteen patients with cranio-facial bone lesion, who had previous pathologic diagnosis of fibrous dysplasia, were ...

Introduction Fibrous dysplasia is a non-hereditary disease of childhood, of unknown etiology, in which fibrous tissue replaces normal bone. There is a wide spectrum of involvement, from asymptomatic isolated bonelesions to severe debilitation and the rare Albright’s syndrome of osteitis fibrosa disseminata, hyperpigmented skin lesions and endocrine dysfunction (Albright et al. 1937). The follow...

BACKGROUND Interpretation of small biopsy fragments from suspected lesions of fibrous dysplasia with unusual clinical and/or radiological features may be challenging due to wide histomorphological spectrum of stromal appearances. Awareness of these variations should improve diagnostic confidence. METHODS We retrospectively studied 26 cases of fibrous dysplasia (F- 19, M- 7; Ages ranged from 1...
متن کاملFocal Hematopoietic Hyperplasia of Rib, Mimicking to Fibrous Dysplasia
Focal haematopoietic hyperplasia is a rare and localized proliferation of the bone marrow to such an extent that it produces a tumor-like expansion hence called as pseudotumor. Radiologically it presents as an osteolytic expansile mass and may mimics with certain bony tumors. We report a case of Focal haematopoietic hyperplasia in the 3rd anterior rib of a 45 year old man clinically presenting ...

Fibrous Dysplasia (FD) is a focal bone lesion occurring sporadically and in hereditary syndromes caused by activating mutations of the G protein alpha subunit. It rarely undergoes malignant transformation. Malignant Fibrous Histiocytoma (MFH) is a sarcoma of soft tissues and may be found as primary sarcoma of the bone or multifocally. Until now only a few cases of malignant transformation of FD...
