Primary spontaneous pneumothorax (PSP) is a common cause of presentation to emergency departments and subsequent hospitalization. Patients with large PSP are treated with tube thoracostomy (TT) and followed up with x-rays. In this study, we investigated the efficiency of bedside ultrasound and compared it with x-ray imaging for the clinical follow-up of PSP patients treated with TT.This is a prospective observational study. After ethical committee approval and written informed consent were obtained, patients who were treated with TT because of PSP were screened...

The aims of this study were to demonstrate the feasibility of obtaining additional cardiac views as proposed on an extended fetal cardiac examination and to see if there was any variation in individual components of that examination stratified by sonographer training, patient body habitus, or equipment. We retrospectively reviewed 200 consecutive detailed second-trimester high-risk fetal obstetric sonograms that included additional extended cardiac views. We analyzed the percentage of the time individual views were obtained, with variation based on (1) a sonographer with greater than 3 years of training compared with a group with 6 to 12 months of training, (2) 2 different ultrasound units, and (3) different body mass indices...

Liposarcoma is the most common paratesticular scrotal malignancy. Ultrasound is the conventional imaging modality for evaluating scrotal masses. Contrast-enhanced ultrasound (CEUS) can provide complementary information by identifying distinct enhancement patterns. We present CEUS findings of 2 concurrent soft tissue masses in 1 patient: a spermatic cord well-differentiated liposarcoma and a retroperitoneal dedifferentiated liposarcoma. We review the Doppler ultrasound, computed tomography, and histopathologic appearances of low- versus high-grade liposarcomas in addition to the utility of CEUS with quantitative analysis in potentially grading liposarcomas...

Among the renal cystic diseases that result in end-stage renal disease, an important hereditary cause is medullary cystic kidney disease, which affects adults in an autosomal dominant pattern. It is characterized by progressive renal failure, tubulointerstitial fibrosis, and formation of small cysts in the renal medulla and corticomedullary junction. While the appearance of medullary/corticomedullary cysts may not be pathognomonic for medullary cystic kidney disease, encountering a patient with renal failure and medullary/corticomedullary cysts should prompt further investigation, given the implication of having the disease...

Piriformis syndrome is a common cause of lumbar, gluteal, and thigh pain, frequently associated with sciatic nerve symptoms. Potential etiologies include muscle injury or chronic muscle stretching associated with gait disturbances. There is a common pathological end pathway involving hypertrophy, spasm, contracture, inflammation, and scarring of the piriformis muscle, leading to impingement of the sciatic nerve. Ultrasound-guided piriformis injections are frequently used in the treatment of these pain syndromes, with most of the published literature describing injection of the muscle...
