Abstract
PDF - Meningiomas in bone are rarely subjected to fine-needle aspiration diagnosis, and those arising in the skull bone with a cystic presentation are rare. A 24-year-old woman presented with subdural hemorrhage, and subsequent radiology depicted an osteolytic mass-like lesion in the sphenoid bone. Intraoperatively, a solid and cystic hemorrhagic lesion mimicking an aneurysmal bone cyst was observed in the sphenoid bone with dural tearing. Frozen cytology showed singly scattered or epithelioid clusters of round to elongated cells intermixed with many neutrophils. Tumor cells had bland-looking round nuclei with rare prominent nucleoli and nuclear inclusions and eosinophilic granular to globoid cytoplasm in capillary-rich fragments. Histology revealed intraosseous meningothelial and microcystic meningioma (World Health Organization grade 1) in right lesser wing of the sphenoid bone. Considering its unusual location and cytologic findings, differential diagnoses included chordoma, chondroma, chondrosarcoma, and aneurysmal bone cyst. The present case posed a diagnostic challenge due to possible confusion with these entities.

Abstract
PDF
- Encephalocele is a relatively rare congenital anomaly which is classified into occipital, parietal, anterior syncipital and anterior basal type regarding to the protrusion site through the bony defect of the skull. Anterior basal type of encephalocele is important in view of it's pathogenesis as well as diagnostic difficulty because of invisibility on external appearance. We have experienced a case which could be best fit to anterior basal encephalocele. This type of encephalocele is extremely rare. This report deals with a case of deadborn of 34 weeks of gestation with body weight of 2400gm and head circumference of 32 cm. There was no evidence of protrusion of brain on external examination. On autopsy the normal brain structure was compressed by abnormal mass of brain with normal consistency which was found in the petrous portion of the parietal area and covered partly by the dura. In this case, there were another associated anomalies, such as atrophy of the left optic nerve, hemihypoplasia of the left mandible, patent ductus arteriosus, bilateral hydrocele, and Meckel's diverticulum.
