Eosinophilic fasciitis (EF), a rare rheumatic disease, usually affects the limbs symmetrically and generally spares the hands and feet. Cases of unilateral hand involvement are rarely reported. Here, we report such a rare case. Ultrasonography demonstrated thickening of the overlying skin and subcutaneous tissue, peripheral deep fascia, myositis of lumbrical muscles and adductor pollicis muscle, and edema surrounding flexor digitorum tendons. It reminds us that EF should be considered in the differential diagnosis of unilateral painful hand swelling despite being uncommon...

Fitz-Hugh-Curtis syndrome (FHCS) is defined as inflammation on the surface of the liver following sexually transmitted chlamydia infection. We successfully observed the microvascular structure of the inflamed portion between the abdominal wall and surface of the liver in an elderly patient with FHCS using a superb microvascular imaging (SMI) system, a new technology developed for observing minute vascular flow. An 80-year-old Japanese female with right dorsal to lateral abdominal pain and fever came to our hospital...

Catheter ablation is an effective treatment in patients with symptomatic atrial fibrillation. Complications are infrequent and usually resolve with minimal or no intervention, but active bleeding due to arterial injury during the vascular access can sometimes represent a life-threatening complication. Contrast-enhanced computed tomography is the standard technique to detect active bleeding, but it may not be immediately available. We report a case of iatrogenic hemorrhage after catheter ablation, in which contrast-enhanced ultrasonography played a decisive role in the recognition of active arterial bleeding due to injury to the right common femoral artery...

PURPOSE: To investigate the association of renal elasticity to microscopic findings of nephron hypertrophy and nephrosclerosis. METHODS: Patients who underwent renal biopsy were enrolled. Renal elasticity was measured by acoustic radiation force impulse, and nephron size (glomerular volume, non-sclerotic glomerular density, and mean profile tubular area) and nephrosclerosis (globally sclerotic glomeruli and interstitial fibrosis) were estimated. Nephron hypertrophy was indicated by larger glomerular volume, larger tubular area, and lower non-sclerotic glomerular density...

Acute funisitis is characterized by the infiltration of fetal neutrophils from the umbilical vessels into Wharton's jelly and presents as fetal inflammation. However, no reports about its prenatal diagnosis using ultrasonography have been published. We encountered one case of oligohydramnios at 26 weeks and another case of threatened premature delivery at 27 weeks of gestation with ultrasonographic findings of non-uniform thickening of Wharton's jelly, a heterogeneous internal echo, and a high echoic line of the umbilical vessel wall...

PURPOSE: The acceleration time (AcT) ratio of the internal carotid artery (ICA) is increased in ICA stenosis. However, there are few reports that have directly compared the AcT ratio to digital subtraction angiography (DSA) findings. METHODS: We evaluated 177 vessels with DSA and carotid artery ultrasonography. The AcT ratio was calculated as AcT of the ICA (ICA-AcT)/AcT of the ipsilateral common carotid artery (CCA). We evaluated the correlation of DSA-NASCET stenosis with the origin of the ICA or the peak systolic velocity (ICApsv) in the stenotic region, ICApsv/peak systolic velocity of the CCA (CCApsv), ICA-AcT, and AcT ratio...

Splenic artery pseudoaneurysm (SAPA) is a relatively infrequently encountered but clinically important vascular change, because it carries a high risk of rupture that warrants prompt treatment regardless of its size. Thus, sufficient knowledge is indispensable when seeing chronic pancreatitis patients or post-traumatic patients. Here, we report two such cases. The first case was a 52-year-old woman known to have chronic pancreatitis who presented with hematemesis and hemodynamic instability in which X-ray computed tomography (CT) and color Doppler sonography (CDS) had difficulty visualizing slow blood flow in SAPA, but superb microvascular imaging (SMI) clearly demonstrated the slow blood flow in SAPA, prompting our therapeutic decision to perform rapid embolization...

A 26-year-old pregnant woman was diagnosed with fetal bladder prolapse following rupture of a patent urachus/urachal cyst, based on the finding of cyst disappearance with replacement with an infra-umbilical, extra-abdominal solid soft-tissue mass, mimicking bladder exstrophy. The neonatal findings confirmed the prenatal diagnosis. The baby was healthy and had a successful surgical correction. This report provides clues to differentiating ruptured bladder prolapse from bladder exstrophy as follows: (1) well-documented urachal cyst with urine-filled mass in the early gestation, (2) development of solid soft-tissue mass shortly after disappearance of the urachal cyst, and (3) no other structural abnormalities (bladder exstrophy is usually associated with abnormal genitalia, epispadias, or pubic diastasis)...

Cardiac hemangiomas are rare benign tumors. Here, we report the case of a man in his 30s who had a cardiac hemangioma with no symptoms. He was being treated with β-blockers for chronic heart failure with hypertensive heart disease at Osaka Minato Central Hospital. Routine echocardiography revealed a mobile spherical mass in the left ventricle that had not been detected on echocardiography performed 4 months previously. Subsequently, the tumor was excised to prevent potential embolic events and was pathologically diagnosed as a cardiac hemangioma...

A 60-year-old male patient presented with intermittent right-sided scrotal swelling for the last 4 months. On ultrasonography, a fluid-filled cavity extending through the right inguinal canal into the scrotum was noted with inferior displacement of the right testis. Multiple papillary hyperechoic lesions with internal vascularity on Doppler ultrasound were protruding into the fluid-filled cavity. Computed tomography showed herniation of the bladder through the right inguinal canal into the scrotum with mural components in the herniated segment...
