Partially cystic thyroid nodules (PCTNs) are common on ultrasound (US). However, there are insufficient data on the prevalence of thyroid carcinoma among such nodules. The purpose of this study was thus to evaluate the prevalence and differentiation of partially cystic thyroid cancers in US-guided fine needle aspiration (FNA).A total of 1342 consecutive patients with 1360 thyroid nodules underwent prospective US diagnosis and FNA biopsy. In total, 281 nodules (20.7%) were partially cystic lesions. The nodules were prospectively analyzed based on US features (ie, solid portion positions, shapes, margins, and microcalcifications) and US diagnosis (benign, suspicious, or malignant)...

INTRODUCTION: The mesodiverticular band (MDB) is an embryologic remnant of the vitelline circulation, which carries the arterial supply to the Meckel diverticulum. In the event of an error of involution, a patent or nonpatent arterial band persists and extends from the mesentery to the apex of the antimesenteric diverticulum. This creates a snare-like opening through which bowel loops may herniate and become obstructed. This report describes 2 rare cases of small bowel occlusion owing to an internal hernia caused by a MDB...

Here we report a case of sclerosing mesenteritis that we diagnosed with needle biopsy under the guidance of computed tomography (CT) and ultrasound (US) observation. An 82-year-old woman presented with appetite loss, weight loss and epigastric pain. CT of the abdomen and pelvis revealed increased density of the mesentery adjacent to the small bowel and enlarged lymph nodes. Sclerosing mesenteritis was suspected, but malignancies, such as lymphoma, were also considered. We performed CT and US-guided needle biopsy with the coaxial technique...

Leslie Noirez, Laurent P Nicod
In the past twenty years ultrasound has been the subject of renewed interest in lung exploration in the broad sense. The necessity of accessing a means of rapid exploration at the bed of the patient in a critical situation has led to the development of a pleuro-pulmonary ultrasound semiology to make it a diagnostic tool of choice which exceeds the strict framework intensive care units and emergency services. With the diagnosis of thoracic tumors or the exploration of interstitial syndromes, it tends to integrate more into the daily practice of the pulmonologist...

Silk suture reaction (i.e., a benign granulomatous inflammatory foreign body reaction) is a rare complication of thyroid surgery. Here, two cases of post-thyroidectomy suture reaction are presented. Both of the patients were female, one is 48 and the other is 34 years old. The patients were presented with neck swelling and leakage of serous fluid from the Kocher's incision. Both patients had normal free T4, free T3, and TSH values. The 48-year-old female patient had a right subtotal and left near-total thyroidectomy 6 years ago and the other had bilateral total thyroidectomy 6 years ago...

Snapping pes anserinus syndrome is an often encountered cause of medial knee snapping. It results from impingement and translation of the gracilis tendon or semitendinosus tendon over the osseous structures of the knee during active flexion and extension. Ultrasonography is often the diagnostic imaging test of choice in cases of mechanical snapping. We report 2 cases of painful snapping pes anserinus and highlight the value of dynamic ultrasound in making an accurate diagnosis so as to direct care.

Introduction A very high number of patients presenting in emergency departments suffer from an unknown infection or rather fever. If diagnostic imaging is necessary ultrasound can be performed. Whether ultrasound is superior to medical history and clinical examination considering the significantly enhanced technology in recent years and hence has to be performed in patients without abdominal symptoms with non-obvious focus cannot be answered by review of the literature. The objective of this study was to evaluate the relevance of abdominal ultrasound in the determination of the site of infection and to analyse whether an abdominal ultrasound for the identification of the source of infection is dispensable in patients in whom history and clinical examination do not indicate an abdominal focus...

PURPOSE OF REVIEW: We review new applications of optical coherence tomography (OCT) technology in neuro-ophthalmology. We also describe new technologies for visualizing the extracranial vessels in the diagnosis of giant cell arteritis (GCA). RECENT FINDINGS: Newer OCT modalities are expanding the evaluation of the optic disc, and are being applied to a number of neurologic conditions such as demyelinating and neurodegenerative disease. Swept-source OCT and enhanced-depth imaging OCT are refining the fine-grained analysis of the optic nerve head in the diagnosis of papilledema and optic nerve drusen...

OBJECTIVE: The standard of care for the diagnosis and follow-up of urolithiasis is unenhanced CT. The hypothesis of this study was that that by using image fusion of subsequent ultrasound (US) with the initial unenhanced CT, ureteral stones can be precisely localized. CONCLUSION: Of the 25 stones founds on unenhanced CT studies, 22 (88%) were confidently identified using US-unenhanced CT fusion within 72 hours after the initial CT scan was obtained. US-unenhanced CT fusion might obviate the need for repeated CT scans for monitoring urolithiasis...
