Patients with a long-standing history of immunosuppression are at significantly increased risk of opportunistic infections. One such group of organisms that may cause these types of infections includes the Nocardia genus, a gram-positive, filamentous rod that demonstrates a branching pattern, is urease-producing and has acid-fast properties. The disease profile of Nocardia varies with manifestations ranging from cutaneous infection to severe pulmonary or central nervous system (CNS) infections, and rarely, osteomyelitis...

PURPOSE/OBJECTIVE(S): A 4-stage non-comparative prospective feasibility study to assess and develop imaging protocols for MRIgRT was opened at the first two centers using MR Linac technology in the UK. The primary aims of this study were to determine a) the acceptability of MR images for target and organ at risk delineation and registration; b) inter/intra observer registration and delineation variation. This work reports on the initial results from a single center. MATERIALS/METHODS: In June 2019, following ethical and regulatory approvals the 2nd UK centre began study recruitment as follows: Stage A: non-patient volunteer imaging to determine sequence suitability for normal tissue in 6 anatomical sites (head & neck (H&N), chest wall/breast, lung/esophagus, abdomen, male and female pelvis)...

Coxarthrosis, or hip osteoarthritis (OA), is one of the main causes of hip pain, which can affect patients of all ages, being one of the most common reasons for patients presenting to the specialized outpatient clinic. The objective of our research was to determine the number of patients with coxarthrosis who presented to the Department of Orthopaedics and Traumatology within the Emergency County Hospital of Drobeta Turnu Severin, between 2017-2019, the sex, age, social environment of the patients. All patients underwent a thorough clinical examination to determine the risk factors, the favouring factors and their correlation with the paraclinical data obtained through imaging investigation (pelvis X-ray, computer tomography and nuclear magnetic resonance)...

Several studies have shown that most peritoneal inclusion cysts (PIC) cases occur almost exclusively in women of childbearing age and patients who have had abdominal or pelvic surgery. We report a case of PIC diagnosed in a 19 years old single adolescent female with chronic pelvic pain and secondary amenorrhea with no prior history of abdominal surgery. A multilocular abnormality in the pelvis and a septated pelvic fluid encompassing the ovaries and extending to the right iliac fossa was revealed by ultrasound images and Magnetic Resonance Imaging (MRI), respectively...

BACKGROUND: Congenital hepatic cysts are relatively rare but are now diagnosed earlier and more frequently with a routine prenatal ultrasound. Solitary liver cysts are divided into simple and solitary intrahepatic biliary cysts, depending on the biliary connection. While some solitary liver cysts are symptomatic in childhood, even in newborns, they are often found incidentally in adults. CASE SUMMARY: A 3-mo-old female infant was admitted to Mogadishu Somali Training and Research Hospital with recurrent vomiting, respiratory problems, and abdominal bloating complaints...

OBJECTIVES: Evaluate deep learning (DL) to improve the image quality of the PROPELLER (Periodically Rotated Overlapping Parallel Lines with Enhanced Reconstruction technique) for 3 T magnetic resonance imaging of the female pelvis. METHODS: Three radiologists prospectively and independently compared non-DL and DL PROPELLER sequences from 20 patients with a history of gynecologic malignancy. Sequences with different noise reduction factors (DL 25%, DL 50%, and DL 75%) were blindly reviewed and scored based on artifacts, noise, relative sharpness, and overall image quality...

BACKGROUND: A well-established definition of obstruction in the setting of congenital hydronephrosis is lacking. Multiple imaging modalities and radiographic characteristics or parameters have been described to help confirm the diagnosis of ureteropelvic junction obstruction (UPJO). We sought to evaluate the change in anterior-posterior renal pelvic diameter (APRPD) following furosemide administration in patients with unilateral hydronephrosis and confirmed UPJO on functional magnetic resonance urography (fMRU) who underwent pyeloplasty...

We present a case of a 48-year-old female who presented with epistaxis. Magnetic resonance imaging (MRI) revealed a mass within the left nasal cavity which was revealed to be a phosphaturic mesenchymal sinonasal tumour. The patient defaulted treatment at this stage and later re-presented with pelvic and groin pain for which plain radiographs and computed tomography (CT) scan demonstrated diffuse osteopenia and multiple pelvic fractures of varying ages. MRI of the pelvis and both thighs revealed abnormal marrow signal of the bones and confirmed the presence of pelvic fractures...

BACKGROUND: Fistulizing perianal Crohn's disease (CD) is a debilitating condition associated with significant morbidity and reduction in the quality of life. Magnetic resonance imaging (MRI) of the pelvis is the preferred imaging modality for the comprehensive assessment of the perianal fistula. There is a paucity of data from India on the MRI spectrum of complex perianal fistula in CD. METHODS: A single-centre cross-sectional analysis of patients with fistulizing perianal CD, who underwent pelvic MRI between January 2020 and December 2021, was performed...

Placenta accreta spectrum encompasses cases where the placenta is morbidly adherent to the myometrium. Placenta percreta, the most severe form of placenta accreta spectrum (grade 3E), occurs when the placenta invades through the myometrium and possibly into surrounding structures next to the uterine corpus. Maternal morbidity of placenta percreta is high, including severe maternal morbidity in 82.1% and mortality in 1.4% in the recent nationwide U.S. statistics. Although cesarean hysterectomy is commonly performed for patients with placenta accreta spectrum, conservative management is becoming more popular because of reduced morbidity in select cases...

BACKGROUND: Ovarian epithelial tumors are common in adults, and their peak incidence of onset is over 40 years of age. In children, most ovarian tumors are germ cell-derived, whereas epithelial tumors are rare and mostly benign. CASE PRESENTATION: This report describes a case of a 14-year-old Chinese girl with ovarian mucinous cystadenocarcinoma. She was admitted with a small amount of bloody vaginal discharge during the past month. Magnetic resonance imaging of the abdomen and pelvis showed a large solid cystic mass lesion in the left ovary...

The aim of this study was to explore the potential of magnetic resonance fingerprinting (MRF), an emerging quantitative MRI technique, in measuring relaxation values of female pelvic tissues compared to the conventional magnetic resonance image compilation (MAGiC) sequence. The study included 32 female patients who underwent routine pelvic MRI exams using anterior and posterior array coils on a 3T clinical scanner. Our findings demonstrated significant correlations between MRF and MAGiC measured T1 and T2 values ( p < 0...

Obstructed hemivagina with ipsilateral renal agenesis (OHVIRA) syndrome is a rare congenital malformation of the Mullerian duct. We report on a 34-year-old female who presented to the emergency department for cramping lower abdominal pain and pelvic pressure with vaginal spotting. Physical exam showed marked swelling in the right adnexa, and laboratory exams were within normal limits except for positive Coronavirus disease 2019 (COVID-19) status. Transvaginal ultrasound revealed 3 well circumscribed, round hypoechoic complex cystic lesions with arterial doppler detected within the peripheral walls...

A female, 1.5 years old, mixed‑breed dog, was presented for left hind limb lameness. Radiographs revealed an irregular periosteal proliferation on the left iliac wing. The clinical condition worsened with generalised enlargement of the lymph nodes, azotaemia, and pyelonephritis. The magnetic resonance imaging of the pelvis and a surgical biopsy diagnosed a mycotic myositis and osteomyelitis of the iliac wing and gluteal muscles. Aspergillus terreus was isolated from culture of urine and lymph nodes aspirates...

BACKGROUND: Tarlov cysts (TC), also known as perineural cysts are meningeal dilations of the posterior nerve root sheath that typically affect sacral nerve roots. TC are usually asymptomatic and found incidentally. We present the case of a patient with an enlarging sacral TC causing pain from spinopelvic instability secondary to extensive bone erosion. Such illustrative case is intended to increase awareness of the potential need for complex spinopelvic reconstruction in atypical instances of large TC...
