Alterations in normal coagulation and hemostasis are critical issues that require special attention in the neurosurgical patient. These disorders pose unique challenges in the management of these patients who often have concurrent acute ischemic and hemorrhagic injuries. Although neurosurgical intervention in such cases may be unavoidable and potentially life-saving, these patients should be closely observed after instrumentation.

A 57-year-old male with liver cirrhosis secondary to amyloid light-chain amyloidosis was admitted to the intensive care unit for the management of delayed hydrocephalus. An external ventricular drain (EVD) was placed for the treatment and monitoring of hydrocephalus. Five days after EVD placement, a head computed tomography scan revealed a tract hemorrhage. However, on repeated imaging, the size of the hemorrhage continued to increase despite aggressive blood pressure control and several doses of phytonadione. Extensive coagulopathy workup was remarkable for low factor VII levels. In that setting, recombinant activated factor VII was administered to normalize factor VII levels, and the tract hemorrhage stabilized.

To the best of our knowledge, this is the first case of spontaneous hemorrhage after EVD placement in the setting of liver cirrhosis-associated factor VII deficiency. Our case highlights the importance of identifying coagulation disorders in neurosurgical patients at high risk for coagulopathy and closely monitoring them postoperatively.

Schwannomas of the abducens nerve are a rare pathology and are encountered less within the cavernous sinus. We describe a case of sixth cranial nerve schwannoma, in the cavernous sinus.

A 50-year-old lady, presented with 2 years history of double vision and left facial numbness that started 6 months before presentation, found to have hyperintense lobulated mass at the left cavernous sinus extending into Meckel's cave with bony remodeling on magnetic resonance imaging. She underwent left frontotemporal craniotomy, combined extra-intradural approach, gross total resection. She had a gradual recovery of the sixth cranial nerve function.

Abducens nerve schwannoma of the cavernous sinus is a rare and challenging tumor. However amenable to surgical intervention with favorable neurological outcome.

In female infants, herniation of the ovaries, fallopian tubes and uterus has been reported. Herniation of the ovaries is a rare congenital condition that may be complicated by strangulation, torsion, and infertility. A 6-week-old female infant presented with visible swelling in the right inguinal region. This case highlights the utility of ultrasonography as a cheap and easily available imaging technique that can be used for the characterization of the hernial contents, and guide the management, further accentuated by the use of color Doppler imaging, of this subtle but crucial entity.Primary symptoms of Crohn's disease usually include, among others, abdominal pain and cramping, recurrent diarrhea, fever and weight loss. The aim of this study was to show the effectiveness of ultrasound in the diagnosis and assessment of the extent of perianal complications in Crohn's disease. Five patients (four boys and one girl) aged from 13 to 16 years, with prolonged pain in the perianal area, which worsened when sitting, were admitted to the Department of Pediatric Gastroenterology between 2017 and 2019. Each patient underwent intestinal ultrasound with a high frequency 7-12 MHz linear probe and transperineal ultrasound to assess the anal canal and the surrounding soft tissues. In each case, the echogenicity of the bowel wall was assessed for mural stratification and possible thickening. Anorectal fistulas were detected in all the five patients. Three patients (12 y.o. male, 12 y.o. female and 16 y.o. male) presented with perianal abscesses drained by fistulas. In the first patient the fistula was limited to the perianal soft tissue (22 × 23 mm); in the second patient it was localized within the ischioanal region (40 × 50 mm); and in the third patient (5-6 mm abscess) the fistula was with a hypoechoic fistulous tract reaching the sphincter. CADD522 datasheet All of the patients were eventually diagnosed with Crohn's disease as a result of further clinical workup. Ultrasound examination is a non-invasive, well-tolerated modality for the evaluation of Crohn's disease activity and its possible complications, e.g. fistulas and abscesses. Ultrasound is especially useful in patients who require repeated follow-up investigations.Glomus tumors or paragangliomas are rare benign neoplasms which are very uncommon in the head and neck region. They grow slowly from paraganglion cells, which serve various regulatory tasks in the body and form the basis of the extra-adrenal neuroendocrine system. They have benign properties, but tend to cause local invasion and expansion to adjacent anatomic structures. The majority of glomus tumor cases are incidental findings, since the clinical symptoms are mostly absent. The purpose of this paper is to distinguish the ultrasonographic features of different glomus tumors located within the neck region, based on their varying anatomical location and space occupying behavior.We report the case of a 40-year-old man presenting at the emergency department with ankle and feet edema due to acute sarcoidosis (Lofgren syndrome). The diagnosis was suggested based on an ultrasound examination showing bilateral asymmetrical tenosynovitis of the flexor tendons with hypervascular subcutaneous cellulitis without any significant ankle and foot joint effusion or synovitis. This case report highlights the crucial role of ultrasound imaging as the first-line diagnostic tool in the investigation of a non-specific clinical condition, when performed by a knowledgeable sonographer with attention to detail. Radiologists performing ultrasound should be aware of the presenting ultrasound pattern of acute soft tissue sarcoidosis, and should include this entity in the differential diagnosis of patients with distal lower extremity swelling, tenosynovitis and hypervascular subcutaneous cellulitis, in order to narrow down the differential diagnosis and facilitate the clinical workup of the patient.Especially in recent years, the use of point-of-care ultrasound by non-radiologist clinicians has become widespread. Point-of-care ultrasound provides rapid responses to the problems of critically ill patients at the bedside. This technique has many important advantages, including being non-invasive, cheap, repeatable, painless, and radiation-free. Numerous studies have revealed the most important clinical benefits of point-of-care ultrasound use by pediatric intensive care providers. The inferior vena cava is a vessel that is highly sensitive to fluid changes. The inferior vena cava diameter can be measured by a point-of-care ultrasound, and represents a critical parameter in assessing the patient's fluid status. The inferior vena cava collapsibility index (in spontaneously breathing patients) and the inferior vena cava distensibility index (in mechanically ventilated patients) are calculated by determined formulas by using maximum and minimum diameters of the inferior vena cava. The indices are important guides for pediatric intensive care providers for managing their patients' fluid treatment. Although some authors claim it is not a reliable method, the technique is coming to fore in intensive care units day by day, and has an increasing trend among pediatric intensive care specialists. Here, we aim to give detailed information on the ultrasonographic inferior vena cava diameter measurement methods, and calculations of the inferior vena cava collapsibility index and inferior vena cava distensibility index, and emphasize the importance of a noninvasive, bedside, and objective method of detecting the volume status of critically ill patients for pediatric intensive care specialists according to the published literature.Despite their considerable clinical significance, intra-abdominal hypertension and abdominal compartment syndrome are rarely discussed in the context of ultrasonography. They occur in critically ill patients, usually hospitalized in intensive care units. Early diagnosis of these conditions is of key importance for prognosis as it allows for proper treatment and prevents high mortality. Although there are various methods for the assessment of intra-abdominal pressure, a measurement using a sensor-equipped catheter placed in the bladder is the gold standard. However, this technique does not allow to identify the etiology of the problem, which is usually resolved by analyzing patient's clinical data supported by imaging findings. Computed tomography is most often used for this purpose. Recent years have proved that point-of-care ultrasonography is also useful in this respect. This issue has become the basis for developing this review paper, which describes the opinion of the experts of the World Society of the Abdominal Compartment Syndrome on the nomenclature, classification and diagnosis of intra-abdominal hypertension. We also presented preliminary data on the role of ultrasound in the diagnosis and monitoring of intra-abdominal hypertension and the contribution of this modality to the choice of appropriate treatment for patients presenting with this clinical condition. A multi-center study used point-of-care ultrasonography to assess the position of a g-tube in the stomach and its contents, intraluminal content status and bowel motor function, the monitoring of gastric drainage and forced intestinal evacuation, the presence of ascites and ascitic status without and after paracentesis. Even when simplified, the method was found to be very useful.The primary technique for detecting the presence and monitoring the development of carotid atherosclerotic plaque is ultrasound. The development of ultrasound techniques has made it possible to precisely visualise not only blood flow, but also vessel walls, including atherosclerotic plaque. Contrast-enhanced ultrasound examination enables one to make an objective observation of atherosclerotic plaque neovascularisation, clearly indicating active inflammation, which is an inherent feature of vulnerable (unstable) plaque. Depending on the examination method used, it is possible to precisely visualise different components of the plaque and its behaviour during blood flow through the vessel lumen or through the neovessels of the plaque, and, consequently, determine the possible presence of inflammation, which is a defining feature of plaque stability. The full utilisation of physical phenomena that underlie contrast-enhanced ultrasound will bring further enormous progress of diagnostic and probably also therapeutic methods for carotid atherosclerosis.
