Frontal bossing is the development of an unusually pronounced forehead which may also be associated with a heavier than normal brow ridge. It is caused by enlargement of the frontal bone , often in conjunction with abnormal enlargement of other facial bones , skull , mandible , and bones of the hands and feet.
Compensatory growth occurs forward at the coronal suture and backward at the lambdoid suture giving respectively a prominent forehead, called frontal bossing, and a prominent back portion of the head, called coning. [10] [11] This is the most common form of craniosynostosis. [13]
Parrot's sign, [3] also known as 'Parrot's nodes' [4] and 'Parrot's bosses', [5] [6] refers to the bony growth noted at autopsy by Marie Jules Parrot and Jonathan Hutchinson on the skulls of children with congenital syphilis (CS) in the 19th century. [2] [7] Later publications also describe it as the frontal bossing that presents in the late ...
Kagami-Ogata syndrome is a rare genetic disease that is caused by mutations on Maternal chromosome 14 or by paternal UPD(14). [1] The main signs of this disease are: polyhydramnios, narrow bell-shaped thorax, coat-hanger-like ribs, abdominal wall defect, enlarged placenta. [2]
Acute periostitis is due to infection, characterized by diffuse formation of pus, severe pain, and constitutional symptoms, and usually results in necrosis.It can be caused by excessive physical activity as well, as in the case of medial tibial stress syndrome (also referred to as tibial periostalgia, soleus periostalgia, or shin splints).
Cranial sutures. A defining characteristic of Crouzon syndrome is craniosynostosis, which results in an abnormal head shape.This is present in combinations of: frontal bossing, trigonocephaly (fusion of the metopic suture), brachycephaly (fusion of the coronal suture), dolichocephaly (fusion of the sagittal suture), plagiocephaly (unilateral premature closure of lambdoid and coronal sutures ...
Early skeletal deformities can arise in infants such as soft, thinned skull bones – a condition known as craniotabes, [15] [16] which is the first sign of rickets; skull bossing may be present and a delayed closure of the fontanelles. Young children may have bowed legs and thickened ankles and wrists; [17] older children may have knock knees ...
The disease was first described by Maroteaux and Lamy in 1962 [4] [5] at which time it was defined by the following characteristics: dwarfism; osteopetrosis; partial agenesis of the terminal digits of the hands and feet; cranial anomalies, such as persistence of fontanelles and failure of closure of cranial sutures; frontal and occipital bossing; and hypoplasia of the angle of the mandible.
