Congenital Lung Malformations: A Pictorial Review of Imaging Findings and a Practical Guide for Diagnosis.

The term congenital lung malformation (CLM) is used to describe a wide range of pathological conditions with different imaging and clinical manifestations. These anomalies stem from abnormal embryological lung development, potentially occurring across various stages of prenatal life. Their natural history can be variable, presenting in a wide range of severity levels and encompassing asymptomatic individuals who remain so until adulthood, as well as those who experience respiratory distress in the neonatal period.

Not always embolism: A case of pulmonary artery intimal sarcoma - The role of the radiologist in early diagnosis.

Introduction: Pulmonary artery intimal sarcoma (PAIS) is a rare malignant neoplasm with imaging features that can mimic pulmonary embolism (PE). It must be recognized early because a radical resection may be useful to prolong survival.

Case Description: A clinical case of a 57-year-old Caucasian male affected by PAIS is presented, which describes the computed tomography (CT) findings found in PAIS and the elements of overlap and differentiation with PE.

Cavitated pulmonary nodules in a female patient with breast cancer: Keep in mind ' infections.

Serratia species are gram-negative bacteria, which could be isolated from soil, water, plants, animals and air. They are responsible for a heterogeneous spectrum of diseases, affecting the central nervous system, the urinary tract, the respiratory tract and the bloodstream. Pulmonary involvement is rare and typically occurs in immunocompromised patients; radiological appearances include haemorrhagic bronchopneumonia, even with the development of pulmonary abscesses and cavitated parenchymal lesions, or diffuse alveolar damage.

Superior mesenteric artery syndrome (Wilkie Syndrome) with unusual clinical onset: Description of a rare case.

Wilkie's Syndrome is a very rare disease caused by reduction of aorto-mesenteric space with consequent duodenum compression. It can combine with left renal vein stenosis which, when symptomatic, is known as "Nutcracker Syndrome". We describe a clinical onset case with epigastric pain without vomiting in a normal weight patient.

Can Conventional and Diffusion-Weighted MR Enterography Biomarkers Differentiate Inflammatory from Fibrotic Strictures in Crohn's Disease?

To retrospectively assess the value of magnetic resonance enterography (MRE) parameters derived from conventional and diffusion weighted imaging (DWI) sequences to differentiate fibrotic strictures from inflammatory ones in adult patients with Crohn's disease (CD), using surgical specimens as the histopathological reference standard. : Twenty-three patients with CD who had undergone surgical resection of ileal strictures with full-thickness histopathologic analysis within 3 months from preoperative MRE were included. Two radiologists blinded to histopathology in consensus evaluated the following biomarkers on MRE images matched to resected pathological specimens: T1 ratio, T2 ratio, enhancement pattern, mural thickness, pre-stenotic luminal diameter, and apparent diffusion coefficient (ADC).

A Case of Nutcracker Syndrome Combined with Wilkie Syndrome with Unusual Clinical Presentation.

BACKGROUND Nutcracker syndrome and Wilkie's syndrome are rare vascular diseases due to the abnormal course of the superior mesenteric artery originating from the abdominal aorta with reduced angle (<22°) and consequent compression of the left renal vein (nutcracker) and duodenum (Wilkie). Here, we report the case of a patient with a rare combination of these 2 syndromes and with unusual clinical manifestation of post-prandial pain. CASE REPORT We describe the case of a young male patient with rapid weight loss, coupled with post-prandial abdominal pain, with sub-acute onset, not associated with other symptoms.

Endometriosis: clinical features, MR imaging findings and pathologic correlation.

Objective: We illustrate the magnetic resonance imaging (MRI) features of endometriosis.

Background: Endometriosis is a chronic gynaecological condition affecting women of reproductive age and may cause pelvic pain and infertility. It is characterized by the growth of functional ectopic endometrial glands and stroma outside the uterus and includes three different manifestations: ovarian endometriomas, peritoneal implants, deep pelvic endometriosis.

Bilateral adrenal neuroblastoma in the infant: Is it an image-defined risk factor?

The treatment of neuroblastoma is based on the International Neuroblastoma Risk Group stratification considering life-threatening symptoms, image-defined risk factors (IDRFs), presence and site of metastases, biology, and histopathology. The authors present an infant with bilateral nonmetastatic adrenal neuroblastoma with favorable biology. Both tumors were resectable and without IDRFs, but bilateral resection was considered mutilating, so it was decided to operate one side only.

Elastofibroma dorsi and the thoracic surgeon: experience with 13 patients.

A total of 13 patients (11 females, average age of 63 years) with elastofibromadorsi were retrospectively analyzed. The disease was confirmed by surgical intervention in five cases. In other patients (n = 8) the diagnosis was achieved on the basis of clinical and radiological features.

Crohn's disease of the small bowel: evaluation of ileal inflammation by diffusion-weighted MR imaging and correlation with the Harvey-Bradshaw index.

Purpose: This study was undertaken to determine the diagnostic capabilities of diffusion-weighted magnetic resonance imaging (DWI) in detecting ileal inflammation in Crohn's disease (CD), and to verify the correlation between the DWI sequences and the Harvey-Bradshaw index (HBI).

Materials And Methods: Twenty patients with an endoscopic-histological diagnosis of CD of the terminal ileum and MR enterography with DWI sequences and HBI were retrospectively selected. Disease activity was visually evaluated on the DWI sequences.

Diffusion-weighted magnetic resonance imaging for predicting and detecting the response of ocular melanoma to proton beam therapy: initial results.

Purpose: The aim of this study was to investigate the utility of diffusion-weighted magnetic resonance (MR) imaging for prediction and early detection of response to proton beam therapy in ocular melanoma.

Materials And Methods: Ten ocular melanoma patients treated with proton beam therapy were enrolled in the study. All patients underwent conventional MR imaging and diffusion-weighted imaging (DWI) before the start of therapy, and after 1, 3 and 6 months of therapy.

DHEA pre-treated patients, poor responders to a first IVF (ICSI) cycle: clinical results.

Purpose: To evaluate the effect of the premedication with dehydroepiandrosterone (DHEA) on the results of the in vitro fertilization (IVF) treatments in a group of women with evidence of diminished ovarian reserve.

Materials And Methods: This experimental, prospective, pre-post study enrolled 29 patients with evidence of diminished ovarian reserve and poor-responders to a previous treatment. They received 75 mg/die of DHEA for a minimum of eight weeks; from the 18th day of the cycle before the stimulation with follicle stimulating hormone (FSH), they took trans-dermal estradiol (E2) (50 mcg every other day).

Could empirical low-dose-aspirin administration during IVF cycle affect both the oocytes and embryos quality via COX 1-2 activity inhibition?

Purpose: To compare qualitative and quantitative ovarian response in idiopathic infertile women treated with low-dose-aspirin (LDA) during in-vitro-fertilization (IVF) cycles (pl) versus untreated ones.

Methods: We conducted an observational-cohort-study on normo-responders patients aged between 25 and 45,years referred to Assisted-Reproductive Unit --University of Padua--in order to evaluate the ovarian response effects (both qualitative and quantitative) after LDA administration. In detail we aim to assess if LDA administration could improve ovarian response, reducing the gonadotropin administration, and if its administration could increase the amount of follicles greater than 16 mm at pick-up, the amount and quality of oocytes retrieved, the amount and quality of embryos, the chance to achieve a pregnancy and to carry it on.

Multidetector CT Dentascan evaluation of bone regeneration obtained with deproteinised bovine graft in residual cavity after mandibular cyst enucleation.

Purpose: This study compared spontaneous bone healing and regeneration obtained with deproteinised bovine graft in residual cavities after mandibular cyst enucleation using computed tomography (CT) Dentascan.

Materials And Methods: Eighty patients with a radiological diagnosis of mandibular cyst underwent surgical enucleation. Patients were divided into a control group (spontaneous healing, 40 patients) and a test group (deproteinised bovine graft, 40 patients).

Endometrial carcinoma: MR staging and causes of error.

Purpose: This study was undertaken to prospectively determine the diagnostic capabilities of magnetic resonance (MR) imaging in detecting myometrial and cervical invasion and lymph node involvement in endometrial carcinoma and to identify the causes of errors in staging endometrial carcinoma.

Pelvic floor imaging: comparison between magnetic resonance imaging and conventional defecography in studying outlet obstruction syndrome.

Purpose: This study prospectively compared the diagnostic capabilities of magnetic resonance (MR) imaging with conventional defecography (CD) in outlet obstruction syndrome.

Materials And Methods: Nineteen consecutive patients with clinical symptoms of outlet obstruction underwent pelvic MR examination. The MR imaging protocol included static T2-weighted fast spin-echo (FSE) images in the sagittal, axial and coronal planes; dynamic midsagittal T2-weighted single-shot (SS)-FSE and fast imaging employing steady-state acquisition (FIESTA) cine images during contraction, rest, straining and defecation.

A cytoplasmatic estrogen receptor related protein (ER-D5 Ag) in breast cancer.

A monoclonal antibody against an Estrogen Receptor Related Protein (EG-D5 AG by Amersham) was analyzed in evaluating hormone dependence in 188 breast cancers, in addition to current index of steroid receptors. The Authors observed that the concentration of this new Antigen is not related with PgR but with ER concentration. In fact, increasing the ER values, increases the concentration of ER-D5 Ag, showing a good correlation between these two tumoral markers.
