Pseudoaneurysms of the scalp are rare. Most common etiology is trauma. The patients usually present clinically with persistent painful swelling in the scalp few days after the trauma. The lesion may or may not be pulsatile clinically. Ultrasonography (US) is the best modality to assess these pseudoaneurysms. It not only helps in the diagnosis, but also to trace the offending arterial branch and helps in treatment. We present two cases of post-traumatic scalp pseudoaneurysms which were diagnosed with US and were managed by US-guided thrombin injection...

Gregory Milligan, John C Moscona
Coronary sinus thrombosis is a rare and often overlooked diagnosis that can have fatal consequences. We report a case of acute coronary sinus thrombosis in a patient with systolic heart failure who had undergone recent right-heart catheterization. The patient presented with recurrent presyncope, syncope, and shortness of breath. An echogenic focus consistent with a coronary sinus thrombus was visualized on transthoracic echocardiography that had not been seen previously on recent imaging. The patient was managed on oral anticoagulation...

OBJECTIVE: Clinical decision making in children with heart disease relies on detailed measurements of cardiac structures using two-dimensional and M-mode echocardiography. However, no echocardiographic reference values are available for the Chinese children. We aimed to establish z-score regression equations for left heart structures in a population-based cohort of healthy Chinese Han children. METHOD: Echocardiography was performed in 545 children with a normal heart...

Amyloid goiter (AG) is defined as the diffuse enlargement of the thyroid gland resulting from extensive amyloid deposition. Imaging findings in AG may vary depending on the amount of amyloid and fat deposition. A few case reports of AG with clinically subacute thyroiditis (SAT)-like syndrome have been published. However, there have been no reports on AG mimicking SAT with clinical and imaging findings. Herein, we present a case of AG mimicking SAT with a detailed report of the clinical and imaging findings.

We report a case of vitelline vein aneurysm detected at 23 weeks of gestation. Few postnatal cases of vitelline vein aneurysm have been reported; however, due to their similar appearances most of them were considered initially as umbilical vein dilatations. The accurate prenatal diagnosis of vitelline vein aneurysm and early postnatal surgical treatment are crucial steps to prevent postnatal obliterative extension of thrombosis that might cause severe neonatal morbidity.

When administered inappropriately, first-trimester misoprostol management of induced or spontaneous abortion can result in loss or damage of a continuing pregnancy. Despite these serious consequences, such misoprostol exposures continue to occur. Unfortunately, contributing factors and preventive measures receive little attention. We describe the cases of 4 women in whom misoprostol was inappropriately administered during management of induced and presumed spontaneous abortion. In each case, careful adherence to published clinical guidance could have avoided the exposures...

Eccrine spiradenoma is a rare, benign, adnexal skin tumor of the sweat gland, which may manifest in any part of the body. It is typically located in the dermal or the subcutaneous fat layer. Eccrine spiradenomas rarely progress to malignant transformation and only a few cases of malignant transformation have been reported. Due to its rarity, there have been few reports about the sonographic appearances of eccrine spiradenoma. We report the sonographic findings in one case of eccrine spiradenoma, located in the subcutaneous fat and the deep dermal layers of the upper arm in a middle-aged woman...

Ultrasound-guided injections such as steroid injections are common procedures involving the musculoskeletal system. They are usually performed after a subcutaneous injection of local anesthetic (LA), which can be painful. In 126 consecutive patients, local anesthesia was performed using ethyl chloride spray prior to a therapeutic ultrasound-guided injection in joints, tendons, or bursae. Ninety-nine (78.5%) patients found the use of ethyl chloride spray helpful. The use of ethyl chloride spray is an effective, patient-friendly alternative to the standard injection of local aesthetic for ultrasound-guided therapeutic musculoskeletal injections with the advantage of a lower cost of $0...

Fetus in fetu (FIF) is an extremely rare anomaly featuring a monozygotic, diamniotic, parasitic twin, enclosed within its host twin. It is characterized by the presence of vertebrae and well-developed organs in a fetiform mass. Only 18 cases of intracranial FIF have been published. Of them, only five cases were prenatally detected. This study prenatally demonstrated triplet FIFs at 31 weeks within amniotic-like sac in the fetal skull, consisting of multiple well-defined organs. The FIF attached to the host twin via body stalk containing a single main feeding artery and vein, representing umbilical vessels...

AIM: To evaluate clinical and imaging outcomes after ultrasound (US)-guided 3% polidocanol (POL) foam-sclerotherapy of venous malformations (VMs). METHODS: We retrospectively evaluated consecutive VM cases over 1.5 years, with 6-month follow-up. US findings were used to classify VMs into four types depending upon extent of anechoic channels, connections to adjacent veins, and dysmorphism. Single or multiple needles were inserted depending upon lesion size, and used to inject up to 8 mL POL per session, every 2 to 4 weeks...

PURPOSE: Pulmonary ultrasound (PU) examination at the point-of-care can rapidly identify the etiology of acute respiratory failure (ARF) and assess treatment response. The often-subjective classification of PU abnormalities makes it difficult to document change over time and communicate findings across providers. The study goal was to develop a simple, PU scoring system that would allow for standardized documentation, have high interprovider agreement, and correlate with clinical metrics...

Ultrasonography is a well-defined and widely accepted technique in the settings of interventional procedures requiring peripheral venous access, either for the confirmation of the vein patency (with the compression test) or for guiding needle insertion. This report describes a case of unsuccessful guidewire passage through the right iliac vein in spite of successful ultrasonography-guided puncture of the femoral vein. On repeat duplex ultrasonography, the Doppler waveform showed a continuous pattern without respiratory phasicity, which was consistent with proximal venous occlusion...

Synovial chondromatosis is a rare, benign, proliferative cartilaginous lesion arising from the synovial tissue, tenosynovium, or bursal lining. We describe the case of a patient who initially presented with multiple axillary masses. Breast ultrasound (US) was requested due to the concern of a breast tumor with axillary lymph node metastases. US study was helpful and provided adequate information to suggest the diagnosis.
