Diffuse alveolar haemorrhage (DAH) leads to acute respiratory failure. This is why it requires rapid diagnosis and implementation of appropriate treatment. The standard diagnosis of a patient with DAH includes laboratory tests, diagnostic imagining (X-ray of the chest, high-resolution computed tomography), and bronchoscopy with bronchoalveolar lavage. We present a description of 2 patients diagnosed with systemic connective tissue disease and DAH, monitored with the help of lung ultrasound. To our knowledge, this is the first description of the use of lung ultrasound in DAH in adult patients...

Recently, it was reported that intra-abdominal thickness (IAT) assessments using ultrasound are most reliable if measured from the linea alba to the anterior vertebral column. These 2 anatomical sites can be simultaneously visualized using a linear array transducer. Linear array transducers have different operational characteristics when compared with conventional curved array transducers and are more reliable for some ultrasound-derived measures such as abdominal subcutaneous fat thickness. However, it is unknown whether linear array transducers facilitate more reliable IAT measurements than curved array transducers...

Adult-onset hypertrophic pyloric stenosis (HPS) is a rare anomaly that can be idiopathic or related to underlying gastric pathology. We describe a case of a 25-year-old man with history of human immunodeficiency virus and osteoglophonic dysplasia who presented with pain and swelling at a gastrostomy site. Computed tomography and upper gastrointestinal barium swallow demonstrated gastric distention and stricture at the distal portion of the gastric antrum. An ultrasound detected HPS. The patient eventually required pyloromyotomy for treatment...

The clinical significance of testicular microlithiasis (TM) in patients with primary extragonadal germ cell tumor (EGCT) is not well understood. When EGCT is suspected, sonographic and physical examination of the testicles should be performed to evaluate for testicular lesion or atrophy; negative testicular ultrasound with current technology virtually excludes the possibility of occult primary lesion. Although EGCTs are known to be associated with elevated level of serum tumor markers, the utility of tumor markers in the presence of TM is not well understood...

OBJECTIVE: To investigate the significance of ultrasound elastography for evaluating the optic nerve in patients with primary open angle glaucoma (POAG). METHODS: This prospective, comparative case series included 40 eyes of 40 patients. Twenty eyes with POAG comprised the POAG group, and 20 eyes of 20 patients without glaucoma who admitted to general eye clinic for near vision glasses comprised the control group. All real-time sonographicelastographic examinations were performed by the same physician...

Ectopic hepatocellular carcinoma (HCC) is rare and there has been no report on ectopic HCC arising from both the bile duct and the gallbladder. It is difficult to establish a correct diagnosis for this kind of HCC based on preoperative imaging. All of the preoperative imaging examinations misdiagnosed the HCC as cholangiocarcinoma in our case. However, via retrospective analysis of this case, we found that the patient was positive for hepatitis virus markers and that a tumor marker (α-fetoprotein) was significantly elevated...

AIM: This study aimed to investigate the clinical significance of liver stiffness and serum alpha-fetoprotein (AFP) in differentiating small hepatocellular carcinoma (HCC) from cirrhotic nodule. METHODS: A total of 95 chronic hepatitis B patients who were diagnosed with small HCC (n = 53) or cirrhotic nodule (n = 42) underwent ultrasound elastography point quantification (ElastPQ) examinations on lesion and background liver. Three stiffness parameters, lesion stiffness value (SV), absolute stiffness difference (ASD) of lesion and background liver, stiffness ratio (lesion/background liver) (SR), and serum AFP were retrospectively analyzed...

This study aimed to determine whether active ultrasound surveillance may obviate the need for surgical resection in selected patients with small testicular lesions (STLs). A retrospective 11-year review was conducted of adults who were diagnosed with an STL on scrotal ultrasonography and who either had orchiectomy or sonographic follow-up during a period of at least 3 months. A total of 101 subjects were enrolled. Ultrasound findings, clinical features, histopathology/follow-up imaging were recorded. Logistic regression analysis was performed to select independent risk factors for the diagnosis of malignancy...

Fetuses with hypoplastic left heart syndrome (HLHS) and intact atrial septum are a particular subset of HLHS neonates with high perinatal mortality. The reported mortality in these patients is 50% to 70%, even with prenatal diagnosis. Prenatal left atrial and pulmonary venous hypertension results in abnormal pulmonary vascular and parenchymal development. The goal of this study was to compare the sonographic appearance of the lungs in fetuses with HLHS/intact atrial septum to neonatal outcome and/or pathology in cases where in utero intervention was performed to open the atrial septum...

PURPOSE: The aim of this study was to assess the intraoperator and interoperator agreement for manual measurements of intima-media thickness (IMT) performed under a strict carotid ultrasound technical protocol. METHODS: Two blinded experienced operators independently performed an ultrasound examination at the distal common carotid of 242 subjects in the same patient's position, diastolic phase, probe type, zooming, and depth. Thirty-six subjects were reevaluated in another time point...

Acute epididymo-orchitis (AEO)-related global testicular infarction (GTI) is rare. We report herein the clinical and ultrasound findings of 6 patients with AEO-related GTI. Seventeen patients with torsion-related GTI were also reviewed and compared. The echotexture of AEO-related GTI ranged from mildly inhomogeneous to diffuse heteroechoic, depending on the severity of testicular necrotic changes. All of the patients showed a juxta-epididymal string-of-bead pattern on color Doppler ultrasound, which was ascribed to patent arteries (5/6, 87%) and collateral vessels (1/6, 13%) in the tunica albuginea...

Ultrasound is increasingly being used in examination of the thorax. The sonographic features of normal aerated lung, abnormal lung, pneumothorax, and intrapleural fluid have been published. The sonographic features of uncommon intrathoracic syndromes are less known. Hydropneumothorax is an uncommon process in which the thoracic cavity contains both intrapleural air and water. Few published examples of the sonographic findings in hydropneumothorax exist. We present 3 illustrative cases of the sonographic features of hydropneumothorax with comparative imaging and a literature review of the topic...

Since the development of portable ultrasonography equipment, this technology has provided clinicians the ability to evaluate a variety of lung pathology at the bedside, but we are still learning how to accurately interpret the acquired images. Adequate interpretation and recognition of certain signs is crucial to diagnosing pathological processes. In addition, such signs must be adequately correlated with the patient's medical condition. For instance, the "lung point sign" has been traditionally considered to be pathognomonic for the presence of a pneumothorax, yet such finding may be present in patients with bullous lung disease without a pneumothorax...

OBJECTIVE: The aim of the study was to analyze the sonographic features of nodular Hashimoto thyroiditis (HT) in patients with diffuse background thyroiditis and normal background thyroid parenchyma. SUBJECTS AND METHODS: Eighty-six patients who had fine-needle aspiration biopsy of 100 thyroid nodules confirmed to be HT and a thyroid ultrasound within 1 year of the biopsy were included in the study. Retrospective analysis of several sonographic features of each nodule was then performed...
