The word "megacephaly" refers to a condition where the head is abnormally large. The IPA phonetic transcription of this word is /ˌmɛɡəˈsɛfəli/. It is spelled with the prefix "mega," meaning large or great, and the root "cephaly," meaning head. The "cepha" part of the word comes from the Greek word "kephale" meaning head. The "y" at the end of the word indicates that it is a noun. This complex medical term illustrates how knowledge of root words and prefixes can help with understanding and spelling unfamiliar words.
Megacephaly, also known as macrocephaly, is a medical term used to describe an abnormally large head size or an excessively enlarged cranium. Derived from the Greek words "mega," meaning large, and "cephaly," meaning head, it refers to a condition characterized by an unusual increase in the circumference or overall size of the head.
Megacephaly can manifest itself in various ways, including an enlarged skull that is disproportionate to the individual's body or age. In infants and young children, it may indicate an early closure of the skull bones or abnormalities in brain development. In some cases, megacephaly may result from an accumulation of cerebrospinal fluid within the brain.
While megacephaly can be a symptom of an underlying medical condition or genetic disorder, it can also occur as an isolated anomaly with no associated health concerns. Some conditions often associated with megacephaly include hydrocephalus, achondroplasia, Sotos syndrome, or neurofibromatosis.
Diagnosis of megacephaly usually involves measuring the circumference of the head and comparing it to standardized growth charts based on age and gender. Imaging techniques such as ultrasound, computed tomography (CT) scans, or magnetic resonance imaging (MRI) may be utilized to evaluate the brain structure.
Treatment for megacephaly focuses on managing any underlying conditions causing the abnormal head growth. This may involve surgical interventions to address hydrocephalus or other cerebrospinal fluid abnormalities. Physical therapy and supportive care may also be recommended to address related developmental delays or complications.

The word "megacephaly" is derived from the combination of two Greek roots: "mega" meaning "big" or "great", and "kephalē" meaning "head". So, the term "megacephaly" literally translates to "big head".
