BACKGROUND: Although Müllerian agenesis is the second most common cause of primary amenorrhea the underlying etiology in the majority of cases is unknown. Müllerian agenesis has been reported as a rare finding associated with chromosomal aberrations of the 22q11 chromosomal region including at least one individual with cat eye syndrome (CES) and 10 individuals with deletions or duplications of the 22q11.2 region. However, a potential link between 22q11 abnormalities and uterine malformations has been difficult to adequately ascertain given the limited case reports in the literature...

Stereotactic body radiation therapy (SBRT) stems from the initial developments of intra-cranial stereotactic radiosurgery (SRS). Despite similarity in their names and clinical goals of delivering a sufficiently high tumoricidal dose, maximal sparing of the surrounding normal tissues and a short treatment course, SBRT technologies have transformed from the early days of body frame-based treatments with X-ray verification to primarily image-guided procedures with cone-beam CT or stereoscopic X-ray systems and non-rigid body immo-bilization...

Vaginal delivery may cause levator avulsion, which may increase the risk of pelvic floor dysfunction (PFD). To explore the morphological changes of the levator ani muscle (including the puborectalis and iliococcygeus) and levator avulsion after vaginal delivery, translabial tomographic ultrasound imaging (TUI) was used to examine 80 women 45-60 days after their vaginal delivery. Subsequently, magnetic resonance imaging (MRI) was performed if at least one-sided puborectalis avulsion was found on TUI. The incidence of puborectalis avulsion in these postpartum women was 13...

INTRODUCTION: Magnetic Resonance Imaging (MRI) of adult female pelvis is a well-established tool in the evaluation of utero-ovarian lesions and is often used to supplement ultrasonography. The need for diagnostic surgical intervention has largely been eclipsed with the advent of MRI, which has become the imaging modality of choice for characterization of pelvic masses. AIM: To assess the role of MRI in female pelvic mass lesions and to exploit the tissue characterization capability of MRI...

A 57-year-old patient was admitted to the Neurology Clinic for hypoesthesia, intense pain in the right chin and double vision. During the hospitalization, the patient developed progressive complete bilateral ophthalmoplegia and numbness of both sides of the chin. Brain CT and MRI scans with gadolinium were normal. Standard laboratory tests on admission were normal. The cerebral spinal fluid examination and the infectious and autoimmune workup were also normal. A thoracic-abdominal and pelvic CT scan revealed two hypodense lesions in the liver, irregular thickening of the gastric and ileal wall, and multiple abdominal adenopathies...

Intensity-modulated radiation therapy, image-guided radiation therapy with fiducial markers and prostate brachytherapy allow the delivery of dose escalation for localized prostate cancer with very low rates of long-term toxicity and sequelae. Nowadays, modern radiotherapy techniques make it possible to shorten treatment time with hypofractionation, to better protect surrounding healthy tissues and to escalate the dose even further. Advances in radiotherapy are closely linked to advances in magnetic resonance imaging (MRI) and/or PET imaging...

Vaibhav Bagaria, Kshitij Chaudhary
INTRODUCTION: Preoperative planning is an important aspect of any orthopedic surgery. Traditionally, surgeons mentally rehearse the operation and anticipate problems based on data available from "radiography" like MRI and CT. 3D printed bio-models and tools, or "3Dgraphy" can simplify this mental exercise and provide a realistic and user-friendly portrayal of this radiographic data. METHODS: Five surgeons participated in this multicenter study. 3D printed biomodels were obtained for 50 surgical cases that included periarticular trauma (24), pelvic trauma (11), complex primary (7), and revision arthroplasty (8)...
