Architectural production has been influenced by a variety of sources. Forms derived from nature, biology and live organisms, had often been utilised in art and architecture. Certain features of the human anatomy had been reflected in design process in various ways, as imitations, abstractions, interpretations of the reality. The correlation of ideal proportions had been investigated throughout centuries. Scholars, art historians starting with Vitruvius from the world of ancient Roman architecture, described the human figure as being the principal source of proportion among the classical orders of architecture...

Intracranial medulloepithelioma is extremely rare and highly malignant in central nervous system. It is a kind of fast-growing tumor and shows a propensity to spread widely throughout the central nervous system. It commonly occurs in infants and young children. We reported a rare case of 2 years old female child with a huge mass diagnosed as medulloepithelioma. Though radiological examination was characteristic for the neoplasm, it was not enough to make a definite diagnosis. Combining with histopathological examination was contributing to diagnose medulloepithelioma and differentiate it from other central nervous system tumors...
