Abstract Background Aggressive angiomyxoma is an infrequent benign tumor that usually occurs in the pelvic region. Pelvic masses have variety of differential diagnosis but some featured findings should prompt the diagnosis of aggressive angiomyxoma by the radiologist. Case presentation A 40-year-old female patient presented with a two-year history of perineal swelling. Radiological examination including gray scale and color Doppler ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI) was consistent with the diagnosis of aggressive angiomyxoma. The patient underwent surgical operation that ensures total resection of the tumor. Conclusion In the case of extensive pelvic soft tissue mass with characteristic imaging findings, the radiologists should take the diagnosis of aggressive angiomyxoma into consideration.

Vascular torsion is a rare renal transplant complication which requires prompt diagnosis and surgery to salvage allograft function. We report here a case of renal allograft torsion with interesting imaging findings on unenhanced CT and color Doppler ultrasound. A 60-year-old woman with a history of pancreas and kidney transplant presented to the emergency room with nausea, vomiting, abdominal pain, and minimal urine output. Unenhanced CT of the abdomen demonstrated an enlarged and malrotated renal allograft with moderate hydronephrosis. Color Doppler ultrasound demonstrated lack of vascularity within the allograft. The patient was taken urgently to the operating room where the renal allograft was found twisted 360 degrees around the vascular pedicle. After the allograft was detorsed, the color of the kidney returned and the Doppler signals for arterial flow improved. Intraoperative biopsy showed no evidence of infarct or acute cellular rejection. The detorsed kidney was surgically fixed in position in its upper and lower poles. Follow-up ultrasound 1 day later demonstrated normal blood flow to the renal allograft and the serum level of creatinine returned to normal.

We report the disease characteristics, diagnosis, and treatment of granulomatous orchitis. A 38-year-old man presented with a history of intermittent swelling, pain, and discomfort in the right testicle of 3 days’ duration. Unenhanced magnetic resonance imaging (MRI) of the testis and scrotum revealed an oval mass in the right testis measuring approximately 17 mm in diameter, with clear borders and a target ring-like appearance from periphery to center. T1-weighted imaging (T1WI) showed uniform low-intensity signals, and T2WI showed mixed high- and low-intensity signals. Diffusion-weighted imaging (DWI) signals were iso-intense, and the outer ring on enhanced scans showed progressive enhancement. We performed radical resection of the right testis under combined spinal–epidural anesthesia. The pathological diagnosis was granulomatous right orchitis. Two months postoperatively, ultrasonography showed no testis and epididymal echo signals in the right scrotum, and no obvious abnormalities; color Doppler blood flow imaging (CDFI) findings were normal. Granulomatous orchitis is rare in clinical practice, and the cause is unknown. The disease involves non-specific inflammation; however, it is currently believed that antibiotics and steroids are ineffective for conservative treatment, and orchiectomy should be actively performed.

Background and Importance: Sacrococcygeal Teratoma (SCT) with medular invasion is rare. Case Presentation: We report a case of an 11-month male infant, with no prenatal history of any abnormality, presenting since birth, a mass in the buttock extended to retrorectum associated with a right side hypotonic limb and monoplegia. Medullar and abdominal pelvic Magnetic Resonance Imaging (MRI) showed a sacrococcygeal tissue mass and intradural lumbosacral invasion with a high level of alpha-fetoprotein. Surgical excision was done successfully with an uneventful follow-up. Conclusion: Despite of the intradural invasion, those SCT are in major cases mature and present low risk of malignancy or recurrence.

Starting a surgical job can feel like learning a completely new language. It may be the first time seeing patients in acute severe pain with a variety of lumps and bumps and a past history of previously unheard of complex operations. It can be easy to get hung up on whether the distended large bowel loop on the X- ray is a caecal or sigmoid volvulus or whether the strangulated hernia is femoral or inguinal. Ultimately, however, the most important point is that, as a junior doctor, it is being able to recognize that the patient is acutely unwell and may require an operation that will save lives. Ironically, a surgical rotation involves little time in the operating theatre— mostly, it will be spent dealing with problems during the peri-­operative period. This may start a week or two before the patient is even admitted, in the shape of a pre- assessment clinic, though these are increasingly nurse- led clinics with minimal input from junior doctors. Such clinics are, however, a good opportunity to see stable patients with interesting pathology and good clinical signs and to establish how well they look before the majority of their large bowel or their stomach is removed. The preoperative preparation of the patient goes beyond bloods and a cursory chat, and will require one to be on the lookout for previously undiagnosed cardiorespiratory or rheumatological conditions, among others, that might affect the patient getting to sleep or staying safely asleep under anaesthesia. Liaising with the anaesthetist about possible sources of difficulty well in advance of the planned procedure will ensure that operations do not get cancelled. The acute abdomen will take centre stage during general surgical takes. A thorough history and sound anatomical knowledge will help create a list of differential diagnoses. Accurate and careful palpation of the abdomen will reveal peritonism and the presence of any masses, and simple bedside observations and tests can greatly aid the diagnosis. Surgical specialties have a heavy reliance on imaging— erect chest X- ray, ultrasound, computed tomography (CT)/ magnetic resonance imaging (MRI) scan— each providing different information for the symp­toms displayed.

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant vascular disorder characterized by spontaneous epistaxis, telangiectasia, and visceral vascular malformations. Hepatic vascular malformations are common, though a minority are symptomatic. Symptoms are dependent on the severity and exact type of shunting caused by the hepatic malformation: Arteriosystemic shunting leads to manifestations of high output cardiac failure, and arterioportal shunting leads to portal hypertension. Radiologic imaging, including ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI), is an important tool for assessing liver involvement. Doppler ultrasonography is the first-line screening modality for HHT-related liver disease, and it has a standardized scale. Imaging can determine whether shunting is principally to the hepatic vein or the portal vein, which can be a key determinant of patients’ symptoms. Liver-related complications can be detected, including manifestations of portal hypertension, focal liver masses as well as ischemic cholangiopathy. Ultrasound and MRI also have the ability to quantify blood flow through the liver, which in the future may be used to determine prognosis and direct antiangiogenic therapy.

Aggressive angiomyxoma is a rare mesenchymal tumor occurring predominantly in the pelviperineal region. Authors present a case of a 70 years female presented with history of distention of lower abdomen with recurrent pain since 6 months. On clinical examination there was suspicion of fibroid. On USG it was reported as huge fleshy, soft tissue mass measuring 20x10x9 cm in lower abdominal flanks and pelvis with vascular pedicle attached to right parametrium. Pan-hysterectomy was performed. Right broad ligament showed mass measuring 18.5x10x6 cm. On histopathological examination it was diagnosed as a case of Aggressive angiomyxoma of broad ligament. We are presenting this case for its extreme rarity, clinicohisto-pathological and radiological findings.

In this work, the related risk factors and perinatal outcomes of pregnant women with gestational diabetes mellitus (GDM) were analyzed based on color Doppler ultrasound (CDU) diagnosis. Backpropagation (BP) algorithm-based CDU imaging algorithm (BPC) was constructed in this study and applied in CDU images of 80 pregnant women with GDM. Besides, amplitude and phase estimation (APES) and low-complexity adaptive beam (LCA) algorithms were introduced for comparison with BPC in turn. It was found that Dice similarity coefficient (96.44%), sensitivity (95.45%), and specificity (91.56%) of BPC were greater than those of APES (83.97%, 85.84%, 78.45%) and LCA (84.74%, 86.29%, 82.35%), while its running time (6.44 ± 1.39 s) was shorter than that of APES (11.87 ± 2.41 s) and LCA (13.76 ± 1.54 s) ( P < 0.05 ). Pregnant women in the experimental group (group B) were older than those in the control group (group A) ( P < 0.05 ). The pulsatility index (PI) and renal artery resistance index (RI) of fetuses in group B (0.95 ± 0.15) were higher than those of group A (0.57 ± 0.24) ( P < 0.05 ). In addition, pregnancy age, family history of hypertension, and abortion history were positively correlated with GDM ( P < 0.05 ). In conclusion, BPC could not only improve diagnosis accuracy in fetuses’ CDU images but also shorten calculation time. Pregnancy age, family history of hypertension, and abortion history were the related risk factors for GDM in pregnant women.

<b><i>Objective:</i></b> To analyze the role of serum sortilin in coronary artery calcification (CAC) and cardiovascular and cerebrovascular events (CCE) in maintenance hemodialysis (MHD) patients. <b><i>Methods:</i></b> One hundred eleven patients with MHD ≥3 months were included in this study. The general data, clinical features, hematological data, and medication history of the patients were recorded. Eighty-five cases were examined by vascular color Doppler ultrasound, cardiac color Doppler ultrasound, lateral lumbar radiography, and coronary artery calcification score. The patients were followed up for a median time of 45 months. The primary endpoint was CCE or death from a vascular event, and the role of sortilin in this process was analyzed. <b><i>Results:</i></b> Among 85 MHD patients, 51 cases (60.00%) had different degrees of CAC. There were significant differences in diabetes, dialysis time, serum phosphorus, calcium-phosphorus product, medical history of phosphate binders, sortilin, and carotid artery plaque between 4 different degrees of calcification groups (<i>p</i> &#x3c; 0.05). Logistic regression analysis showed that diabetes (OR = 5.475; 95% CI: 1.794–16.71, <i>p</i> = 0.003), calcium-phosphorus product (OR = 2.953; 95% CI: 1.198–7.279, <i>p</i> = 0.019), and sortilin (OR = 1.475 per 100 pg/mL; 95% CI: 1.170–1.858, <i>p</i> = 0.001) were independent risk factors for CAC. During the follow-up, 28 cases of 111 patients (25.23%) suffered from CCE. There were significant differences in CCE between mild, moderate, and severe CAC groups and noncalcification groups (<i>p</i> &#x3c; 0.05). Cox regression analysis showed that diabetes mellitus (HR 3.424; 95% CI: 1.348–8.701, <i>p</i> = 0.010), CAC (HR 5.210; 95% CI: 1.093–24.83, <i>p</i> = 0.038), and serum sortilin (HR = 8.588; 95% CI: 1.919–38.43, <i>p</i> = 0.005) were independent risk factors for CCE. Besides, we proposed a cutoff value of 418 pg/mL for serum sortilin level, which was able to predict the occurrence of CCE with 75.0% sensitivity and 71.9% specificity. The area under the curve was 0.778 (95% CI: 0.673–0.883). <b><i>Conclusion:</i></b> Sortilin is newly found to be independently associated with CAC and CCE in MHD patients.
