Subungual squamous cell carcinoma is very rare, but it is the most frequent primary malignant tumor of the nail bed. Therefore, its diagnosis and treatment are crucial to ensure a favorable prognosis. We present the sonographic findings in a case of a subungual squamous cell carcinoma. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound, 2017.

BACKGROUND: To investigate the agreement between Kupffer phase of Sonazoid contrast-enhanced sonography (CEUS) and hepatobiliary phase of gadoxetic acid-enhanced MRI in the evaluation of focal liver lesions (FLLs). METHODS: One hundred fifty-four FLLs in 154 patients who underwent both Sonazoid CEUS and gadoxetic acid-enhanced liver MRI were included in this retrospective study. FLL visibility on the Kupffer-phase images was graded as one (invisible or isoenhancing), two (vaguely visible or vaguely hypoenhancing), or three (clearly visible or clearly hypoenhancing), and that on the hepatobiliary-phase images of MRI was graded as one (invisible or hyper/isointense), two (vaguely visible or weakly hypointense), or three (clearly visible or strongly hypointense)...

Proliferating trichilemmal tumor (PTT) is a rare tumor that originates from the outer root sheath of a hair follicle. About 90% of PTTs occur on the scalp. The sonographic findings of PTT in the subungual region have not been reported previously. In our case, sonography showed a heterogeneous mass containing echogenic foci with no detectable intratumoral vascularity. These echogenic foci probably represent keratin and cholesterol. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound, 2017.

Patients with the complaint of ingested foreign body commonly present in the emergency department. Radiographic imaging is always done for the purpose of localization. However, radiolucent materials like wood are not easily picked up on CT scan. We report the case of a 33-year-old male patient who presented with the complaint of progressive abdominal pain and history of ingestion of a toothpick. It was removed by endoscopic ultrasound-guided localization-assisted targeted endoscopic dissection. Endoscopic ultrasound-guided localization reduced the length and depth of the required incision and helped to minimize the risk of damage to the surrounding tissue...

IgG4-related disease is a relatively newly described entity with findings that historically have been confused with a variety of other diseases with markedly different treatments and prognoses, including Sjogren's syndrome and MALT lymphoma. We present a case of IgG4-related disease of the salivary glands and review the literature on sonographic findings of IgG4-related disease. By connecting sonographic features of IgG4 disease with common ancillary features of IgG4 disease in other sites (pancreas, hilar lymph nodes, biliary tree, thyroid, and retroperitoneum), radiologists can play a pivotal role in the early diagnosis and identification of IgG4-related disease...

Lymphangioma of the mesocolon is very rare. We report two cases of surgically resected and histologically proven mesocolic lymphangioma in adults. In both cases, ultrasound revealed a large cystic mass with multiple thin septa in the lower abdomen. A peculiar finding was the large craniocaudal sliding movement of the mass synchronized with the patient's respiration, which was a clue to the diagnosis of mesenteric lymphangioma. © 2017 Wiley Periodicals, Inc.

A preterm newborn infant, delivered at 30 weeks of gestation and 965 g birth weight, developed respiratory distress with resistant hypoxia after a central catheter line was inserted via the right venae brachialis on postnatal day 21. Left-sided massive pleural effusion, collapsed left lung with air bronchograms, and bidirectional shunting through reopened ductus arteriosus were detected by targeted neonatal echocardiography. Hydrothorax was drained under sonographic guidance, producing a milky-white fluid biochemically compatible with parenteral nutrition...

A cesarean scar pregnancy is a rare type of ectopic pregnancy. Induced abortion by local methotrexate (MTX) injection is an effective management approach. We describe a case in which a large intrauterine vascular lesion appeared after the sonographic-guided local injection of MTX, which successfully induced the abortion of the cesarean scar pregnancy. Although a cesarean scar pregnancy may be safely treated with a local MTX injection, close follow-up, including serum β-human chorionic gonadotropin level measurement and Doppler sonography, is needed because an intrauterine vascular lesion could develop even after a successfully induced abortion...

BACKGROUND: To investigate the effects of Valsalva maneuver (VM) on retrobulbar blood flow parameters in healthy subjects. METHODS: Participants without any ophthalmologic or systemic pathology were examined in supine position with color and pulsed Doppler imaging for blood flow measurement, via a paraocular approach, in the ophthalmic artery (OA), central retinal artery (CRA), central retinal vein (CRV), nasal posterior ciliary artery (NPCA), and temporal posterior ciliary artery (TPCA), 10 seconds after a 35- to 40-mm Hg expiratory pressure was reached...

Lingual node metastasis from early-stage squamous cell carcinoma of the tongue is uncommon and difficult to detect. We present a case of a lingual lymph node metastasis from an early tongue cancer. Sonography demonstrated a small nonpalpable lingual node on the floor of the mouth. The patient underwent complete surgical resection and had no evidence of recurrence 5 years later. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound, 2017.

The anterior complex of the fetal brain is a group of structures that are important to evaluate during the routine anatomic survey to exclude several serious brain malformations. These structures include the cavum septum pellucidum, anterior horns, interhemispheric fissure, callosal sulcus, and corpus callosum. The relationship between these structures is easily remembered with the presented visual cartoon. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound, 2017.

REVIEW
Divya Singh, Ladbans Kaur
Over the years, cesarean section has played a pivotal role in reducing maternal and perinatal morbidity and mortality. With the rising trend of this surgery, a substantial number of pregnant women have a cesarean section scar. The scar can serve as the abode of grave conditions in subsequent pregnancies, namely cesarean scar pregnancy, morbidly adherent placenta, and scar dehiscence. Sonography has emerged as a robust tool for the diagnosis of these potentially life-threatening conditions. This review highlights the key sonographic features of various complications that can occur at the cesarean scar site in subsequent pregnancies...

So Young Park, Gou Young Kim, Young Soo Chun
Proliferative fasciitis is a benign entity involving the subcutaneous tissues and fascias, characterized by the proliferation of fibroblast-like spindle cells and ganglion-like cells. However, proliferative fasciitis may be easily confused with sarcoma clinically and pathologically, because it appears as a rapidly growing painful mass and has histologic features such as high cellularity, bizarre morphologic patterns, mitotic figures, and diffuse infiltrative proliferation. Imaging findings of proliferative fasciitis have been very rarely reported...

We report the case of a 22-year-old athlete who sustained a blunt thoracic trauma to the right chest causing a costal cartilage fracture. Plain radiographs revealed no abnormalities while sonographic (US) examination performed a week later because of persistent pain led to the diagnosis of a displaced fracture of the right tenth costal cartilage. A follow-up US examination confirmed the healing of the fracture and allowed the patient to return to competitive sport activity. We recommend the use of US in patients with persisting pain after thoracic trauma with negative plain radiographs of the ribs to rule out radiographically occult costal cartilage fractures...

This review summarizes the current evidence regarding the diagnostic accuracy of sonography (US) in women with deep infiltrating endometriosis (DIE). It is well known that transvaginal ultrasound (TVUS) can detect ovarian endometriomas with a high degree of sensitivity. In recent years, US has also been used to detect DIE. In the hands of an experienced sonologist, the sensitivity and specificity of TVUS in the detection of DIE is comparable to those of MRI. TVUS can eliminate the need for an MRI in the majority of patients and reduce the need for diagnostic laparoscopy, proving to be an important tool in preoperative planning...

OBJECTIVES: Orthostatic hypotension (OH) is controversially regarded as the cause of orthostatic dizziness in Parkinson's disease (PD). We sought to evaluate whether cerebral autoregulation is an alternative cause for orthostatic dizziness in PD patients, using transcranial Doppler monitoring during head-up tilting. METHODS: Forty-five PD patients with dizziness, 13 PD patients without dizziness, and 10 age-matched healthy controls were enrolled. Participants were divided into the following four groups: patients with dizziness and OH (group 1, n = 22), patients with dizziness but no OH (n = 23, group 2), patients without dizziness (n = 11, group 3), and age-matched healthy controls (n = 10, group 4)...

No published case of Wolman's disease has described the prenatal sonographic findings. We present a case in which a third-trimester sonographic examination demonstrated fetal hepatomegaly and bilateral adrenal echogenicity suggestive of diffuse calcification. Wolman's disease, also known as lysosomal acid lipase (LIPA) deficiency, is a rare autosomal-recessive disorder characterized by complete absence of the LIPA enzyme. The diagnosis of Wolman's disease was made postnatally by biochemical testing, which indicated absence of LIPA enzyme activity and gene sequencing, which confirmed homozygosity for the G66V mutation within the LIPA gene...

BACKGROUND: To determine the prognostic relevance of prior imaging studies in the evaluation of patients referred for renal ultrasound (US) examination to investigate abnormal renal function tests. METHODS: We conducted a retrospective study of 208 consecutive renal US examinations performed for abnormal renal function tests. RESULTS: 68% (142/208) of patients reviewed for the study had prior abdominal imaging with 15% (21/142) receiving that imaging within 1 month prior to the renal US study and 56% (80/142) within the prior year...
