INTRODUCTION: We present a robot-assisted approach to surgical treatment of UPJ obstruction associated with crossed renal ectopia in a male infant. METHODS: A 31 year-old woman presented at 37 weeks gestation for prenatal hydronephrosis and delivered at 39 weeks. Renal ultrasound identified the bladder and right kidney in a crossed ectopic position in the left pelvis, and MRI showed the cystic lesion to be hydronephrosis associated with a ureteropelvic junction obstruction of the crossed ectopic right kidney...

Hyperpolarized (13) C magnetic resonance imaging (MRI) may be used to non-invasively image the transport and chemical conversion of (13) C-labeled compounds in vivo. In this study, we utilize hyperpolarized (13) C MRI to evaluate metabolic markers in the kidneys longitudinally in a mouse model of partial unilateral ureteral obstruction (pUUO). Partial obstruction was surgically induced in the left ureter of nine adult mice, leaving the right ureter as a control. (1) H and hyperpolarized [1-(13) C]pyruvate MRI of the kidneys was performed 2 days prior to surgery (baseline) and at 3, 7 and 14 days post-surgery...

Multiple myeloma (MM) and osteosarcoma (OS) are two common bone malignancies, however, the simultaneous occurrence of both primary bone tumors in the same patient has not been reported in the United States to date. We present a unique case in which both malignancies present concurrently in a 72-year-old man. Results of spinal magnetic resonance imaging (MRI), radiographic skeletal survey, and hematological workup established the initial diagnosis of MM. Approximately three months later, the patient was admitted with severe right hip pain and shortness of breath and was evaluated with computed tomography (CT) of the right hip, abdomen, pelvis, and chest, revealing an osseous mass with a "sunburst" pattern in the right hip, and several calcified nodules in the lungs...

Background: Cowper's syringocele is a rare condition, uncommon in the adult population. It is more common in the pediatric population. Patients could be asymptomatic or present with irritative and/or obstructive symptoms. Ultrasonography (US) of perineal region, pelvis MRI, or urethrography are the most often used diagnostic modalities. Surgical treatment is indicated in all symptomatic patients. Endoscopic approach is preferred over open surgery. Unroofing of syringocele with cold knife or holmium yttrium aluminium garnet (YAG) laser is effective treatment...

PURPOSE: Sensitive visualization of recurrent prostate cancer foci is a challenge in patients with early biochemical recurrence (EBR). The recently established (68)Ga-PSMA-11 PET/CT has significantly improved the detection rate with published values of up to 55% for patients with a serum PSA concentration between 0.2-0.5 ng/mL. The increased soft tissue contrast in the pelvis using simultaneous (68)Ga-PSMA-11 PET/MRI might further improve the detection rate in patients with EBR and low PSA values over PET/CT...

A 30-year-old immunocompetent female presented with right flank pain since 3 years. MRI revealed a large well-defined T1 and T2 hypointense mildly enhancing lesion in the right anterior pararenal space displacing the right kidney and encasing the right ureter with T2 hyperintense wall thickening of the left renal pelvis and ureter. A provisional diagnosis of solitary fibrous tumour was kept. Bilateral double J stenting was done for hydronephrosis. Surgical debulking of the lesion was done with biopsy from the left periureteral wall thickening and was found to be myelolipoma on histopathological examination...

BACKGROUND: The design of seating systems to improve comfort and reduce injury would benefit from improved understanding of the deformation and strain patterns in soft tissues, particularly in the gluteal region. METHODS: Ten healthy men were positioned in a semi-recumbent posture while their pelvic and thigh region was scanned using a wide-bore magnetic resonance imaging (MRI) scanner. Independent measurements of deformation for muscles and fat were taken for the transition from non-weight-bearing to weight-bearing loads in three stages...

In MR only radiation therapy planning, generation of the tissue specific HU map directly from the MRI may improve radiation therapy planning. The aim of the work is to generate and validate substitute CT (sCT) scans generated from standard T2 weighted MR pelvic scans in prostate radiation therapy dose planning. A Siemens Skyra 3T MRI scanner with laser bridge, flat couch and pelvic coil mounts was used to scan 39 patients scheduled for external beam radiation therapy for localized prostate cancer. For sCT generation a whole pelvis MRI was acquired...

OBJECTIVE: The tumors of the head of the pancreas are one of the leading causes of cancer-related death in Western countries. The current gold standard for these tumors is a Whipple procedure. This procedure did not change in its surgical steps since when it was initially introduced in 1935. More recently, a laparoscopic approach with similar outcomes has been described. The aim of this paper is to describe the laparoscopic surgical technique performed in our unit, reporting single center postoperative outcomes...

Chondrosarcomas (CS) are tumors affecting mainly pelvis, long bones and ribs in middle aged people; involvement of head and neck is rare and nasal septum location is exceptional. We report the follow-up of an 85-year-old patient suffering from head and neck CS. Magnetic resonance imaging (MRI) showed a mass originating from nasal septum. The patient underwent to debulking surgery and adjuvant hypofractionated radiotherapy with excellent tolerability and no evidence of recurrence after 16 months. Hypofractionated radiotherapy delivered with advanced technique (helical tomotherapy) allowed to deliver high doses radiation in elderly patients with limited toxicity...

Markedly elevated androgen levels can lead to clinical virilization in females. Clinical features of virilization in a female patient, in association with biochemical hyperandrogenism, should prompt a search for an androgen-producing tumor, especially of ovarian or adrenal origin. We herein report the case of a 60-year-old woman of Pakistani origin who presented with the incidental finding of male pattern baldness and hirsutism. Her serum testosterone level was markedly elevated at 21 nmol/L (normal range: 0...
