INTRODUCTION: Metal-on-metal (MoM) large head total hip arthroplasties (THAs) were discontinued early after their introduction because of the high number of failures due to adverse reaction to metal debris (ARMD). Aim of this study is to report the clinical outcome at a mid-term follow-up (FU) of a series of large-head MoM THA. METHODS: In this prospective study, 25 hips (24 patients, 3 males, 21 females, mean age 62.44 years) who have undergone primary THA with large head (diameter ⩾36 mm) MoM prosthesis were evaluated...

BACKGROUND: Uterine fibroids are a common benign tumor and can be symptomatic, necessitating resection. Surgical myomectomy is an effective treatment option with a risk of disseminating occult uterine leiomyosarcoma (LMS), creating a need for an effective presurgical screening protocol. Clinical collaboration with contrast-enhanced MRI including T2 and diffusion-weighted imaging (DWI) can be utilized as a screening exam. PURPOSE: To review the accuracy and feasibility of an interdisciplinary prospective contrast-enhanced MRI pelvis with DWI screening system for LMS prior to fibroid resection...

Yiping Huang, Qifang Tian
RATIONALE: The incidence of spontaneous perforations in pyometra occurs rarely, only 0.01% to 0.5% in gynecological patients, with high mortality and morbidity. The clinical manifestation of perforated uterine pus is similar to that of gastrointestinal perforation, but the gynecological symptoms are not so obvious, which makes preoperative diagnosis difficult. Here, we report a rare case of peritonitis with laparotomy of pyometra. PATIENT CONCERNS: An acute abdominal pain and purulent vaginal discharge developed in a 72-year-old woman who underwent an emergency laparotomy because of signs of diffuse peritonitis and in a state of shock...

Avascular necrosis (AVN) of the femoral head is a well-recognized complication of steroid treatment. Exogenous glucocorticoids' administration and alcoholism are the most common nontraumatic etiologies. AVN secondary to endogenous hypercortisolism (HC) is rare; very few case reports are available on this complication. We describe a 28-year-old female that has presented an AVN with Cushing's syndrome. Biochemical investigations confirmed HC. Magnetic resonance imaging (MRI) showed a pituitary adenoma that was resected transsphenoidally...

Renal ectopia and fusion anomalies are Congenital Anomalies of the Kidney and the Urinary Tract (CAKUT) that are usually incidentally detected and asymptomatic. Patients affected present a higher risk of complications like recurrent urinary tract infections or obstruction. Pancake kidney (PK) is one of the rarest types of renal anomaly with complete fusion of the superior, mild and inferior poles of both kidneys in the pelvic cavity. Each kidney has its own excretory system with two ureters that do not cross the midline...

A wide variety of fistulae occur in the female pelvis, most of which cause significant morbidity. Diagnosis, characterization, and treatment planning may be difficult using traditional imaging modalities such as fluoroscopy and computed tomography. To date, there is no comprehensive literature review of the radiologic findings associated with various types of female pelvic fistulae, and furthermore, none dedicated to magnetic resonance imaging (MRI). In this article, we seek to provide a broad overview of the MRI characteristics of female pelvic fistulizing disease in combination with epidemiologic and clinical characteristics...

Granulosa cell tumors (GCTs) are rare sex cord-stromal tumors of the ovary. They may present with features of hyperestrogenism. We present a case of a 29-year-old nulliparous female, with infertility and oligomenorrhoea, initially managed with a provisional diagnosis of polycystic ovarian syndrome. She did not respond to multiple cycles of ovulation induction with clomiphene citrate. Later, an ovarian mass was detected, and she was initially planned for laparoscopy. Magnetic resonance imaging pelvis revealed a solid-looking mass in the ovary, with increased vascularity...

BACKGROUND: Optimal imaging for children with pediatric malignant melanoma (MM) is unknown. METHODS: We reviewed clinical and imaging findings of patients with American Joint Commission on Cancer (AJCC) stage IIC-IV MM treated on our institutional MEL06 trial. All patients had baseline brain magnetic resonance imaging/computed tomography (MRI/CT), positron emission tomography/computed tomography (PET/CT), CT chest, abdomen, and pelvis (CTCAP). Patients on stratum A (PEG-interferon, where PEG is pegylated; AJCC IIC, IIIA, IIIB; n = 16) had imaging every 6 months; stratum B1 (PEG-interferon and temozolomide; unresectable measurable disease, metastatic, or recurrent; n = 2) had PET/CT scans every 2 months and brain imaging studies every 4 months; stratum B2 patients (PEG-interferon and temozolomide; unresectable nonmeasurable, metastatic, or recurrent, n = 3) had imaging every 4 months...

PURPOSE: Aneurysmal bone cyst (ABC) is a rare skeletal tumor usually treated with surgery/embolization. We hypothesized that owing to similarities with giant cell tumor of bone (GCTB), denosumab was active also in ABC. METHODS: In this observational study, a retrospective analysis of ABC patients treated with denosumab was performed. Patients underwent radiologic disease assessment every 3 months. Symptoms and adverse events were noted. RESULTS: Nine patients were identified (6 male, 3 female), with a median age of 17 years (range 14-42 years)...

Use of mesenchymal stem cells from bone marrow has gained significant popularity. The iliac crest has been determined to be an effective site for harvesting mesenchymal stem cells. Review of the literature reveals that multiple techniques are used to harvest bone marrow aspirate from the iliac crest, but the descriptions are based on the experience of various authors as opposed to studied anatomy. A safe, reliable, and reproducible method for aspiration has yet to be studied and described. We hypothesized that there would be an ideal angle and distance for aspiration that would be the safest, most consistent, and most reliable...
