BACKGROUND: To explore the relationship between fetal Transverse Cerebellar Diameter (TCD) and menstrual gestational age (GA) and to generate normative references (nomogram) of the fetal TCD in some pregnant women in Southwest Nigeria. METHODS: Four hundred pregnant women with a singleton fetus between 14 and 38 weeks GA were enrolled. The TCD and other biometric parameters (biparietal diameter, head circumference, abdominal circumference, and femur length) as well as the cerebellar appearance were analyzed and correlated with the GA...

AIM: Atherosclerosis remains the pathological basis of myocardial infarction and ischemic stroke. Early and accurate identification of plauqes is crucial to improve clinical outcomes of atherosclerosis patients. Our study aims to evaluate the potential value of fibroblast activation protein inhibitor (FAPI)-04 PET/CT in identifying plaques via a preclinical rabbit model of atherosclerosis. METHODS: New Zealand white rabbits were fed high-fat diet (HFD), and randomly divided into the model group injured by the balloon, and the sham group only with incisions...

INTRODUCTION AND IMPORTANCE: Uterine arteriovenous malformation (UAVM) can be present at birth or acquired later, often after trauma like cesarean delivery. It can cause severe vaginal bleeding but may have no symptoms. What makes our case special, other than being a rare condition, is the surgical technique used. CASE PRESENTATION: A 24-year-old woman came in with abdominal pain at 38 weeks pregnant. She had a cesarean delivery 13 months before. She had an uncomplicated repeat cesarean but bled heavily after from uterine atony...

An 8 yr old male German shorthaired pointer was presented on July 4, 2022, for acute abdominal and testicular pain. The dog was vasectomized at an unknown age under the care of his previous owners. The dog had an enlarged, painful left testis, scrotal edema, and an enlarged, nonpainful prostate. Abdominal ultrasound revealed mild peritoneal and retroperitoneal effusion, orchiepididymitis, enlarged ductus deferentes and testicles, and suspected benign prostatic hyperplasia versus prostatitis. Peritoneal effusion cytology revealed seminoperitoneum with marked neutrophilic inflammation...

PURPOSE OF REVIEW: Surgery is a cornerstone in the management of pancreatic cancer and precancerous pancreatic lesions. However, many patients are not suitable candidates for surgery at the time of diagnosis for various reasons. Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) appears to be a promising treatment option for patients who are ineligible for surgery for management of pancreatic adenocarcinoma (PDAC), and pancreatic neuroendocrine tumors (PNETs), and pancreatic cystic lesions (PCLs)...

It has been proposed that formation of abdominal aortic aneurysm (AAA) is part of a systemic arterial dilatative disease. However, arteries in the upper extremity are scarcely studied and it remains unclear whether both muscular and elastic arteries are affected by the proposed systemic arterial dilatation. The aim of this study was to investigate diameter and stiffness of muscular and elastic arteries in arterial branches originating from the aortic arch. Twenty-six men with AAA (69 ± 4 years) and fifty-seven men without AAA (70 ± 5 years) were included in the study...

Hepatic sparganosis (HS) is extremely rare and has not been previously reported in Eastern China. We report the diagnosis and treatment of a patient with HS from Xuzhou City, Jiangsu Province, China. The patient was admitted due to an acute biliary tract infection, and the symptoms improved after treatment at the Gastroenterology Department. During an ultrasound examination on admission, an abnormal echo was incidentally discovered at the junction of the left and right lobes of the liver. Thereafter, upper abdominal computed tomography (CT) and magnetic resonance imaging (MRI) non-contrast and contrast-enhanced examinations, and serum tumor biomarker examination were completed...

PURPOSE: Ultrasound-guided percutaneous biopsy (USPB) of the native kidneys is the preferred diagnostic method for several nephrological conditions in both adult and pediatric populations. Conventionally, native kidney biopsies are conducted with patients in the prone position (PP). However, an alternative approach involving the supine oblique antero-lateral position (SALP) has been explored, particularly for individuals who are obese, elderly, or critically ill. METHODS: This study aimed to assess the feasibility and outcomes of USPB performed in SALP with a Free-Flank setting (FF-SALP) in pediatric patients (Group A) compared to adults (Group B)...

Many ultrasound-guided procedures are available for administering analgesia via peripheral nerve blockade. This systematic review aims to compare different ultrasound-guided procedures to determine which procedure is better suited for pediatric abdominal surgeries. The objective is to understand the efficacy of ultrasound-guided procedures for postoperative pain management in children undergoing abdominal surgeries and to identify which procedure takes less time and is better suited for a particular surgery...

INTRODUCTION: Chimney technique (chimney graft in abdominal aortic aneurysm repair [ChEVAR]) can be used to treat patients with pararenal aortic aneurysm unfit for open surgery and not suitable for custom-made fenestrated endograft. Since almost 1 in 5 patients undergo a reintervention within 3 years, features associated with higher risk of complications need to be investigated to tailor the follow-up schedule to each patient. The aim of our study was to assess the impact of mural thrombus in the pararenal aorta on perioperative and follow-up complications after ChEVAR...

OBJECTIVE: To compare the performance of the abdominal handheld point-of-care ultrasonography (POCUS) Butterfly-iQ to gold standard transvaginal ultrasonography (US) in identifying the position of intrauterine devices (IUDs) in the hands of a medical doctor specialised in ultrasonography. METHODS: In this diagnostic accuracy study, a single operator conducted abdominal POCUS followed by conventional transvaginal US. Seventy patients utilising copper or hormonal IUDs were assessed between June 2021 and October 2022...

Core stability training is crucial for competitive athletes, individuals who want to improve their health and physical performance, and those undergoing clinical rehabilitation. This study compared the ultrasound (US) muscle thickness of the abdominals and lumbar multifidus (LM) muscles between seven popular trunk stability exercises performed using hollowing and bracing maneuvers. Forty-four healthy young adults, aged between 21 and 32 years, performed a plank, bird dog, beast crawl, dead bug, Pilates tap, bridge, and side planks using the bracing and the hollowing maneuver...

Dirofilaria immitis is a mosquito-borne nematode-causing canine heartworm disease, with adult worms localized in the pulmonary arteries and right heart. In rare cases, ectopic migration might occur, and adults and blood circulating microfilariae can be found in unusual organs or fluids (e.g., eyes, abdominal cavity, bone marrow, and urine). A 17-year-old mixed-breed female dog was presented in a private veterinary clinic in Italy for hematuria and dysuria. Physical examination showed cardiac mitral murmur with marked respiratory distress and cyanotic mucous membranes after handling...

Cornual ectopic pregnancy, though rare, presents significant challenges in diagnosis and management. This case report details the clinical presentation and successful treatment of a 22-year-old primigravida experiencing symptoms of abdominal pain, nausea, and vomiting, ultimately diagnosed with an unruptured left cornual ectopic pregnancy. Employing a multidisciplinary approach involving clinical suspicion, beta-human chorionic gonadotropin (β-hCG) measurements, and transvaginal ultrasound findings, we underscored the importance of timely intervention to avert adverse outcomes...

Inguinal bladder hernia (IBH) is a rare clinical condition that may present as scrotal swelling. Most patients are asymptomatic and found incidentally at the time of herniorrhaphy. IBH continues to pose a challenge to surgeons before, during, and even after herniorrhaphy. This case report aims to describe the case of the incarcerated right inguinal hernia containing the small bowel and the urinary bladder herniation. An 81-year-old male presented to the emergency department with complaints of abdominal pain, distension, and swelling in the right groin...

Tuberculosis poses a significant public health challenge, especially in highly endemic countries. Rarely, it appears as an abdominal mass resembling a malignant abdominal tumor and can be misleading on imaging, so early diagnosis remains a challenge, and confirmation may require invasive examinations such as laparotomy. The most characteristic radiological appearance is that of a solid, hypervascular, or peripherally enhancing mass with a hypodense center. We present a case of retroperitoneal tuberculosis that simulated a teratoma on imaging...

UNLABELLED: Aortic mural thrombus (AMT) in the absence of aneurysm or atherosclerosis is a rare clinical finding and an uncommon cause of peripheral arterial embolization. AMT in a normal artery is usually attributed to systemic hypercoagulability. We describe a case of subacute lower limb ischemia due to AMT associated with active ulcerative colitis (UC). A 46-year-old man with active UC was referred to our hospital for the evaluation and treatment of left leg pain. Ultrasound and contrast computed tomography showed occlusion of the left popliteal artery, and an AMT in the abdominal aorta between the inferior mesenteric artery and the aortic bifurcation...

AIM: Pituitary stalk interruption syndrome is a relatively rare disease. Patients with this disease usually have different degrees of short stature in adulthood. The purpose of this case report is to highlight a special case of unusually elongated limbs with excessive height growth and congenital absence of uterus and ovary, so as to improve clinicians understanding of the atypical manifestations of pituitary stalk interruption syndrome and provide reference for the clinical diagnosis and treatment of the disease...

OBJECTIVES: Clinical examination alone cannot reliably rule out significant traumatic abdominal injury. Computed tomography (CT) has become the primary method for evaluating blunt abdominal trauma and clinicians rely heavily on it to rule out abdominal injury. Ultrasound examination may miss significant abdominal injury particularly in stable patients. The use of a contrast agent improves ultrasound sensitivity to visceral abdominal injuries. The objective of this diagnostic study is to compare bedside contrast enhanced ultrasound (CEUS) performed by emergency physicians to CT in hemodynamically stable adults for the assessment of blunt abdominal trauma and evaluate CEUS accuracy outcomes...
