INTRODUCTION Heterotopic ossification occurs when bone develops in tissues which usually don't undergo ossification. Heterotopic mesenteric ossification, also known as intra-abdominal myositis ossificans, is a rare and benign form of ossification, usually related with previous abdominal surgery or trauma. PRESENTATION OF CASES We report two cases of heterotopic ossification both after multipl...

BACKGROUND The high variations of background luminance, low contrast and excessively enhanced contrast of hand bone radiograph often impede the bone age assessment rating system in evaluating the degree of epiphyseal plates and ossification centers development. The Global Histogram equalization (GHE) has been the most frequently adopted image contrast enhancement technique but the performance i...

The premature fusion of some the sternal ossification centers and obliteration manubrio-sternal joint caused a rare deformity called CurrarinoSilverman syndrome. Patients present an abnormally short sternum with forward angulation at junction. Cardiopulmonary diseases spinal deformities are most frequent related disorders. It was also described as component Turners Noonans syndromes.

disodium hemiphthalate glycyrrhetinic acid (dhga) possesses anti-inflammatory and analgestic activities. in our research, this agent was injected intraperitoneally to mice, according to the following schedule.1) 25 mg/kg, 50mg/kg & 75mg/kg at 7th day of pregnancy.2) 50 mg/kg & 75mg/kg at 8th day of pregnancy.3) 50mg/kg & 75mg/kg at 9th day of pregnancy.dhga with doses of 50mg/kg and 75mg/kg at ...

Mechanical forces are essential for normal adult bone function and repair, but the impact of prenatal muscle contractions on bone development remains to be explored in depth in mammalian model systems. In this study, we analyze skeletogenesis in two 'muscleless' mouse mutant models in which the formation of skeletal muscle development is disrupted; Myf5(nlacZ/nlacZ):MyoD(-/-) and Pax3(Sp/Sp) (S...

OBJECTIVE A presentation of the clinical and pathogenic aspects of choroidal ossification. CASES PRESENTATION We report three clinical cases of choroidal ossification: choroidal osteoma, ossified choroidal hemangioma and total ossification of the choroid. The three patients underwent complete eye examination. The optical microscopy of a sample of ossified choroidal tissue revealed a spongy, o...

BACKGROUND AND PURPOSE A thorough knowledge of fetal growth and development is key to understanding both the normal and abnormal fetal MR imaging findings. We investigated the size and signal intensity of the normal pituitary gland and the intrasphenoidal ossification around the Rathke pouch in formalin-fixed fetuses on MR imaging. MATERIALS AND METHODS Thirty-two fetuses with undamaged brain...

Demineralized bone matrix has been successfully commercialized as an alternative bone graft material that not only can function as filler but also as an osteoinductive graft. Numerous studies have confirmed its beneficial use in clinical practice. Heterotopic ossification after internal fixation combined with the use of demineralized bone matrix has not been widely reported. In this paper we de...

We describe a case of intramuscular vascular malformation with extensive ossification within the posterior compartment muscles of leg which grossly mimicked long bone leading to equinus deformity of foot. Phleboliths and calcifications are characteristic of vascular malformations, while massive ossification is rare. To our knowledge, no extensive ossified vascular malformation within the leg mu...
