Enlargement of the fetal spleen is usually found secondary to systemic diseases and is frequently associated with hepatomegaly. By far, the most common causes of fetal splenomegaly are infectious. Other etiologies responsible for this sign are hemolytic anemia, congestive cardiac failure, metabolic disorders, and rarely, leukemia, lymphoma, and histiocytosis.We report a case of prenatal splenomegaly diagnosed at 35 weeks, confirmed in the postnatal period. The postnatal workup showed the newborn had a familial type 3 form of hemophagocytic lymphohistiocytosis (HLH)...

Meig syndrome is the triad of benign ovarian tumor, ascites, and pleural effusion. Pseudo-Meig syndrome mimics the Meig syndrome triad; however, in pseudo-Meig syndrome, the ovarian tumor usually represents a primary malignancy or metastases. Differentiating Meig from pseudo-Meig syndrome is challenging both clinically and with diagnostic imaging but is important because prognoses for these distinct entities are drastically different. Evidence-based sonographic prediction models are valuable because they can aid in this distinction...

Jiayi Xing, Jian Wang, Shanshan You, Jianchu Li
Drains are routinely used after thyroidectomy and lateral neck dissection. In rare cases, the drainage tube is broken and retained in the neck. It is difficult to identify the sonographic features of the remnant tube due to variable reasons. However, through comparative and phantom observations, we noticed the double-tract sign of the tube wall and drainage holes as the key points to solving this problem. We report such a case of the ultrasound-guided localization of a broken drainage tube that was retained in the patient...

Hua Xin, Jie Li, Hai-Yang Hu
BACKGROUND: Childhood mortality due to pneumonia is high. Chest radiography is the primary imaging modality used for the evaluation of pneumonia in children. Lung ultrasonography (LUS) is a newer, alternative diagnostic method that has been gaining popularity in recent years. We conducted a meta-analysis to summarize the diagnostic usefulness of LUS for childhood pneumonia. METHODS: All studies included in this meta-analysis were retrieved from PubMed, Elsevier's Science Direct, and Springer, and by manual searches including the use of reference lists, through March 31, 2017...

The aim of this pictorial review is to describe the technical advances achieved through the application of 4-dimensional (4D) ultrasound using spatiotemporal image correlation (STIC) over conventional 2-dimensional ultrasound in the prenatal detection of congenital heart disease (CHD). Spatiotemporal image correlation is a volume imaging technique that simplifies fetal heart studies while providing more diagnostic information than is typically available from traditional 2-dimensional studies. Four-dimensional software allows the study of cardiac anatomy and function during a single cardiac cycle and has greatly contributed to diagnostic enhancement of CHD...

This study was to evaluate the correlation between birth weight and the distance between distal rectal pouch and perineum (P-P distance) and to determine a cutoff value for P-P distance to diagnose low-type imperforate anus in neonates with low-birth weight (LBW).We included 15 neonates with LBW (mean weight, 2012 ± 470 g; range, 906-2452 g) and imperforate anus (surgically confirmed: 11 low type and 3/1 intermediate/high type), who underwent ultrasonography on the day after birth. Type of imperforate anus was defined based on the International Classification of Anorectal Anomalies...

OBJECTIVE: This study aimed to evaluate the ultrasonographic pattern of cervical lymph nodes (CLNs) and whether levothyroxine with prednisone therapy is effective for lymphadenopathy in patients with Hashimoto thyroiditis (HT). METHODS: This retrospective study was looking at patients with confirmed diagnosis of HT who underwent comprehensive neck ultrasound examination. We reviewed sonographic findings in 127 patients with HT, 234 euthyroid patients with goiter, and 122 healthy subjects...

OBJECTIVE: The aims of this study are to evaluate the utility of sonoelastography for parotid gland masses and to determine which cutoff strain ratio (SR) would be best for the differentiation between benign and malignant lesions. METHODS: From August 2015 to December 2016, 39 parotid gland masses were examined prospectively by ultrasonography and strain sonoelastography. Elastographic scores were determined by a 4-point scoring method. Interventional procedures were performed on all patients after sonographic examinations...

The purpose of our study was to determine if a textural analysis metric can be implemented to improve diagnosis of adenomyosis by ultrasound.We retrospectively identified 38 patients with a magnetic resonance imaging (MRI) diagnosis of uterine adenomyosis that also had a pelvic ultrasound within 6 months. We also identified 50 normal pelvic ultrasound examinations confirmed by a normal pelvic MRI within 6 months as a control group. A region of interest (ROI) was subsequently placed on the study population ultrasound image corresponding to the area of adenomyosis on MRI...

Jia-Wu Li, Qiang Lu, Yan Luo
Hepatic vein stenosis after liver transplantation is a relatively rare complication that could even result in graft loss. However, it is difficult to arrive at a definite diagnosis at the early stage of postoperation, and there are few researches on ultrasonic shear wave elastography in the diagnosis of hepatic vein stenosis. We report the case of an 11-year-old male patient with cirrhosis due to hepatolenticular degeneration who received an auxiliary left hemiliver graft from his uncle. Massive ascites developed in 4 days after the operation...

Breast lymphoma is uncommon, and it usually involves breast parenchyma and ipsilateral axillary lymph nodes. We report rare cases of cutaneous T-cell lymphoma involving the skin and subcutaneous fat layers mimicking panniculitis of the breasts in a 33-year-old male patient who presented with a growing palpable mass and pain in both breasts and in 17-year-old female patient who presented with an indolent palpable breast mass for 1 year. Extranodal natural killer/T-cell nasal-type and subcutaneous panniculitis-like T-cell lymphomas were diagnosed after skin punch biopsies...

Abdominal ultrasound of a 28-year-old man with chronic abdominal pain and vomiting demonstrates a dilated aperistaltic distal esophagus, which was confirmed on follow-up esophagram as achalasia. The 2 main types of achalasia are primary and secondary. Primary achalasia occurs with the loss of postganglionic neurons resulting in failed distal esophageal relaxation. Secondary achalasia is esophageal narrowing due to nondenervation causes. The diagnosis of achalasia is typically made with manometry and barium esophagram...

Risks associated with isolated great saphenous vein (GSV) thrombosis remain controversial. The purpose of this study is to identify the risk of pulmonary embolism (PE) in patients with isolated GSV thrombosis, particularly those with thrombus within 3 cm of the sapheno-femoral junction. A retrospective chart review of color flow Doppler lower extremity venous ultrasound examinations from an academic hospital from 2011 to 2016 was conducted. Seventy-eight patients were identified as having acute thrombus in their GSV and were then further stratified based on the presence or absence of concomitant deep venous thrombosis (DVT)...
