BACKGROUND: The American Thyroid Association (ATA) recommends fine-needle aspiration (FNA) biopsy of nodules measuring >1.5 cm with low-suspicion sonographic patterns or >1.0 cm with high/intermediate-suspicion features. Routine biopsy of nodules <1 cm is not recommended. However, despite these recommendations, subcentimeter nodules are often referred for FNA biopsy. METHODS: This was a retrospective chart review of consecutive thyroid FNAs during an 18-month period (1157 patients, 1491 nodules, 2016-2017) to evaluate age, sex, medical history, diagnoses, and follow-up...

Uterine artery pseudoaneurysm (UAP) is an uncommon cause of postpartum hemorrhage. We present a case of a 19-year-old woman 6 weeks postpartum after low transverse cesarean delivery with recurrent heavy vaginal bleeding requiring a blood transfusion. Transvaginal sonogram revealed a UAP. Embolization of the uterine artery was performed, with resolution of her symptoms.

Platelets modulate clinically relevant yet incompletely understood tissue regeneration processes, and platelet rich plasma (PRP) has been previously used with some success in various non-reproductive medical contexts. Here, we extended PRP application to ovarian tissue with a view to document impact on ovarian reserve among women attending for infertility treatment. PRP was freshly isolated from patients (n= 4) with diminished ovarian reserve as determined by at least one prior IVF cycle canceled for poor follicular recruitment response or estimated by serum AMH and/or FSH, no menses for ≥1 year...

Thyroid cancer management has moved to less extensive surgery in lesions with favorable criteria. Our study evaluated if the sonographic (US) size of thyroid nodules is a reliable criterion to determine the extent of surgery in patients with papillary thyroid carcinoma (PTC). A retrospective study was performed to evaluate thyroid nodules measuring <10 mm in the preop sonogram with a permanent pathology of PTC. Patients were subdivided into two groups based on the US size: A (1-5 mm) and B (6-10 mm). Statistical correlations were made for the presence of the following unfavorable criteria: multifocality, capsular invasion, angio/lymphatic invasion, extrathyroidal invasion, and presence of metastases...

We present a case of a premature infant with a presumed obstructive uropathy found to be a megalourethra leading to a perinatal postrenal failure. A megalourethra - an uncommon cause of urethral dilatation - is a congenital, non-obstructive anomaly of the penile erectile tissue. We think that a distal stenosis resulted in dysplasia of the penile tissue and an aspect of a megalourethra. Further diagnostic workup included urinary tract sonograms, a voiding cystourethrogram and MAG3 scintigrafy. Initially the patient was managed with supportive care such as a suprapubic urinary catheter, followed by surgical intervention (Bengt Johanson)...

Persistent urogenital sinus (PUGS) is a rare anomaly whereby the urinary and genital tracts fail to separate during embryonic development. We report a three-year-old female child who was referred to the Sabah Women & Children Hospital, Sabah, Malaysia, in 2016 with a pelvic mass. She had been born prematurely at 36 gestational weeks via spontaneous vaginal delivery in 2013 and initially misdiagnosed with neurogenic bladder dysfunction. The external genitalia appeared normal and an initial sonogram and repeat micturating cystourethrograms did not indicate any urogenital anomalies...

A silent solid endocrine tumor of pancreas, intraductal adenocarcinoma of pancreas, is the fourth leading cancer-related death in the US. However, it is expected to become the third leading cause by 2030 owing to delayed diagnosis and slow progress in management. Chronic pancreatitis is at risk for pancreatic ductal adenocarcinoma (PDAC). PDAC is diagnostic with transabdominal sonogram, blood test such as carbohydrate antigen 19-9 (CA 19-9), and imaging. PDAC has a dismal prognosis. The survival rate in 5 years is barely 6%, while late detection rate is 80-85% with unresectable stage upon diagnosis...

A spectrum of vascular complications can be seen in pediatric liver transplant patients, including occlusion and hemodynamically significant narrowing of the vessels that provide inflow to or outflow from the graft. Intraoperative Doppler ultrasound (US) has the potential benefit of identifying vascular complications in pediatric liver transplant patients prior to abdominal closure. Importantly, intraoperative Doppler US can be used as a problem-solving tool in situations such as position-dependent kinking of the portal or hepatic veins, or in suspected vasospasm of the hepatic artery...

BACKGROUND: The noninvasive encapsulated follicular variant of papillary carcinoma (nEFVPTC) has recently been reclassified to "noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP)," removing this entity from the malignant category. This re-categorization has had major implications for clinical management. NIFTP has overlapping cytohistologic features with papillary thyroid carcinoma (PTC) and with follicular adenomas (FA), but sonographic data comparing NIFTP to PTC and FA is lacking...

Mammography is the gold standard screening technique in breast cancer, but it has some limitations for women with dense breasts. In such cases, sonography is usually recommended as an additional imaging technique. A traditional sonogram produces a two-dimensional (2D) visualization of the breast and is highly operator dependent. Automated breast ultrasound (ABUS) has also been proposed to produce a full 3D scan of the breast automatically with reduced operator dependency, facilitating double reading and comparison with past exams...
