A cytology negative rare tumor with the presentation of pseudotumor cerebri clinical symptoms: diffuse leptomeningeal glioneuronal tumor
Diffuse leptomeningeal glioneuronal tumor is characterized by hydrocephalus, leptomeningeal involvement in the absence of a primary parenchymal mass, and negative cerebrospinal fluid (CSF) cytology. It is an extremely rare and difficult tumor to diagnose as no mass can be biopsied and it mimics infectious, rheumatologic, and inflammatory pathologies. An 11-year-old girl presented with complaint...
متن کاملNewly Identified Characteristics and Suggestions for Diagnosis and Treatment of Diffuse Leptomeningeal Glioneuronal/Neuroepithelial Tumors
Diffuse leptomeningeal glioneuronal tumor is unique for communicating hydrocephalus, diffuse leptomeningeal enhancement, cystic changes, absence of tumor cells in cerebral spinal fluid, and a cell population of both glial and neuronal copositivity. It has likely been misdiagnosed as mixed glioneuronal tumors, oligodendrogliomas, and neuroepithelial tumors. Children with signs of this tumor are ...
متن کاملGiant keratocystic odontogenic tumor: a challenging diagnosis
The keratocystic odontogenic tumor, although a benign lesion, is peculiarly aggressive with a high recurrence rate. Its involvement with the maxillary antrum is atypical. We report the unusual case of a 20-year-old male patient with an extensive antral tumor associated with an impacted third molar, which was initially misdiagnosed as a dentigerous cyst. Clinical, radiographic, and histopatholog...
متن کاملPrimary Diffuse Leptomeningeal Gliosarcomatosis
Primary diffuse leptomeningeal gliomatosis (PDLG) is a rare condition with a fatal outcome, characterized by diffuse infiltration of the leptomeninges by neoplastic glial cells without evidence of primary tumor in the brain or spinal cord parenchyma. In particular, PDLG histologically diagnosed as gliosarcoma is extremely rare, with only 2 cases reported to date. We report a case of primary dif...

vealed elevated protein level of 72 mg/dl and 3 white blood cells with no neoplastic cells, therefore providing no evidence of malignancy or CNS infection. Antiepileptic medications were started, and the patient underwent a right temporal brain and leptomeningeal biopsy. Pathology revealed idiopathic leptomeningeal inflammation and fibrosis without brain involvement. The patient improved clinic...
