Multifocal osteosarcoma is diagnosed when there are two or more lesions in the skeleton without presence of pulmonary metastases. It is further classified as synchronous type when the patient is demonstrated to have more than one lesion simultaneously at presentation and is known as Synchronous Multifocal Osteogenicsarcoma (MOGS). We report a case of synchronous MOGS showing its multimodality imaging findings including nuclear scan findings with pathological correlation.
Intramuscular hemangiomas are rare benign congenital neoplasms of vascular origin. They account for less than 1% of all hemangiomas and less than 20% of these are found in head and neck and present in 2nd and 3rd decade. The masseter is the most frequently involved site in the head and neck. Because of their infrequency, deep location and unfamiliar presentation, these lesions are seldom correctly diagnosed clinically and usually present as facial swelling causing facial asymmetry. A case of intramuscular hemangioma occurring in masseter muscle of an 8-year-old girl is presented here. Ultrasonography, color Doppler and Gd-enhanced MRI were performed and a presumptive diagnosis of hemangioma was considered which was subsequently confirmed by excision biopsy.
This was a prospective study conducted in pregnant patients with high risk factors who got admitted in the Department of Obstetrics and Gynaecology at Care Hospital, Jamnagar during the period from May 2018 to September 2020.
Background: High-risk pregnancies causes many adverse perinatal outcomes. Doppler ultrasound is a non-invasive technique to study the feto-maternal circulation to guide the clinical management.
Objective: This study aims at evaluating the role of colour Doppler in high-risk pregnancies and their perinatal outcome.
Materials and Methods: This was a prospective study carried out for 29 months in the Department of Radiology with antenatal women in the age group of 18-35 years with singleton pregnancy of gestational age of <28 weeks to >35 weeks having high-risk factors considered in study. The risk factors considered were pregnancy induced hypertension (PIH), gestational diabetes, anemia, oligohydramnios, polyhydramnios and IUGR. Doppler study of umbilical artery and fetal middle cerebral artery (MCA) arteries was done and amniotic fluid index (AFI) was measured. Parameters in the form of resistive index, pulsatility index, and systolic/diastolic ratio were taken. obstetric history was taken with regular interval follow up.
Results: The study was carried out with 50 patients. High-risk pregnancy was more common in the age group of 21-25 years. The most common high-risk factor in pregnancy was oligohydramnios which accounted for 30% of cases. Out of 50 high-risk pregnancies, 5 (10 %) of cases resulted in intrauterine growth restriction (IUGR). Out of 50 high-risk cases, in 36 cases, umbilical artery findings were abnormal. 3 patients had intrauterine death (IUD) and 27 patients had poor perinatal outcome. Umbilical artery abnormality showed significant sensitivity and negative predictive value for adverse (poor + IUD) perinatal. Correlation was seen between high risk pregnancy and need of emergency caesarean section and induction and associated adverse perinatal outcome.
Conclusion: Combination of different arterial waveform study enhance the diagnostic accuracy in identifying those intrauterine growth restricted foetuses that were at risk.
Keywords: Colour Doppler, high risk pregnancy, perinatal outcome.
The Musculoskeletal manifestations of COVID have been well characterized and include bone infarcts, osteonecrosis, osteitis, fasciitis,
tenosynovitis, myositis, myonecrosis, and joint effusion. The mechanism for myositis includes immune-mediated damage, ICU-acquired
weakness, toxic myopathies, and possibly direct viral muscle destruction. Corticosteroids induced suppression of osteoblasts, apoptosis of
osteocytes and reduced blood ow to the bone result in weak bones. Risk factors include male gender, use of multiple type of corticosteroids, higher
dose of corticosteroid for prolonged duration, alcohol or tobacco abuse and cardio vascular ailments. We aimed at providing MRI evidence of postCOVID musculoskeletal manifestations. Patients with musculoskeletal symptoms from among the many cases of post-COVID sequelae admitted
to the G. G. hospital in Jamnagar based on MRI results were studied along with review of the literature. Most common observation was
osteonecrosis with most common site being femoral head. Post diagnosis, most patients with high grade of osteonecrosis were managed surgically,
meanwhile, myonecrosis was managed with physiotherapy and medical management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
