AbstractUterine adenomyosis can be diagnosed on ultrasonography (US) and magnetic resonance imaging (MRI) with a high degree of accuracy. Adenomyosis is a myometrial process that can appear as diffuse or focal on imaging. Diffuse adenomyosis typically causes uterine enlargement, while focal adenomyosis can mimic other myometrial lesions, such as leiomyomas. Imaging features frequently seen on US include a heterogenous thickened myometrium and myometrial cysts. On MRI, widening of the junctional zone, whether focal or diffuse, and the presence of myometrial cysts, either simple or hemorrhagic, support the diagnosis of adenomyosis. Despite these characteristic imaging appearances, there are several gynecologic pathologies which can mimic adenomyosis and it is important to be vigilant of these when interpreting cross-sectional imaging exams. The decision to evaluate patients with US or MRI is contingent on multiple factors, including availability of the necessary technology and expertise for the latter. However, MRI appears to offer greater specificity and positive predictive value for the diagnosis of adenomyosis.

The detection of vaginal lesions has increased with the expanding use of cross-sectional imaging. Magnetic resonance imaging (MRI)—with its high-contrast resolution and multiplanar capabilities—is often useful for characterizing vaginal masses. Vaginal masses can be classified as congenital, inflammatory, cystic (benign), and neoplastic (benign or malignant) in etiology. Recognition of the typical MR imaging features of such lesions is important because it often determines the treatment approach and may obviate surgery. Finally, vaginal MR imaging can be used to evaluate post-treatment changes related to previous surgery and radiation therapy. In this article, we will review pertinent vaginal anatomy, vaginal and pelvic MRI technique, and the MRI features of a variety of vaginal lesions with pathological correlation.

Pyriform Aperture

ABSTRACT Congenital neonatal pyriform aperture stenosis (CNPAS) is a rare but potentially lethal condition that causes respiratory distress. The characteristic narrowing of the pyriform aperture along with other associated craniofacial dysmorphism is diagnosed using cross-sectional imaging such as computed tomography (CT) and magnetic resonance imaging. CT scan is the imaging of choice for confirming and characterizing CNPAS. Infants are obligate nasal breathers in the first 5 months of life. Hence, a high degree of clinical suspicion, prompt imaging diagnosis and adequate respiratory support is critical to help reduce the morbidity of this condition.

This chapter on “Imaging” examines the relative advantages and disadvantages of computed tomography (CT) and magnetic resonance imaging (MRI) scans. It compares the modalities to each other and to gross neuropathology. For several decades, neurologists have been able to view cross-sectional images of living patients. Analogous to gross neuropathology, cross-sectional imaging displays the brain as an entire organ but does not demonstrate microscopic tissue or cellular pathology. By allowing practitioners to view sections of brain and spinal cord in vivo, imaging has improved neurologic practice and facilitated clinical research. This chapter deals with imaging topics that are important to the neurologist. The timing of scans, the effects of gravity, and the importance of plane of section are considered. Imaging is compared to gross neuropathology, and MRI is compared to CT.

Retroperitoneal lymphangiectasia is a very rare lymphatic disorder characterized by abnormal proliferation of lymphatics. We present series of 3 cases of retroperitoneal lymphangiectasia which are diagnosed in our institute with the help of Ultrasonography (USG), Computed Tomography (CT) and Magnetic resonance imaging (MRI) of abdomen and pelvis with unusual clinical presentation. We include clinical features and imaging findings of this disorder with its pathogenesis and diagnosis. Two of the cases were clinically masquerading as hernia and one case was mimicking varicocele. Thorough clinical examination and USG, colour Doppler, CT and MRI are extremely helpful imaging investigation that aid in differentiating these lesions from hernia/ varicocele and the cross sectional imaging like CT and MRI can  depict the anatomical extent of the disease.

Introduction: Chondrosarcoma is a tumour with a cartilaginous matrix frequently encountered in long bones and the pelvis with rare sinonasal location. Patient and methods: We report the case of a 25-year-old patient who was referred to us for an extension work-up for sinonasal chondrosarcoma confirmed by anatomopathological examination. Results: Facial magnetic resonance imaging (MRI) confirmed by a CT scan showed an osteolytic tumour process of the hard palate and walls of the left maxillary sinus that was locally advanced. Conclusion: The sinonasal location of a chondrosarcoma is rare. Characterized by cross-sectional imaging, confirmation was provided by histological assessment.

Idiopathic carotidynia (IC) is a rare and poorly understood syndrome consisting of unilateral neck pain, tenderness, and increased pulsations over the affected carotid bifurcation. A growing body of evidence supports the hypothesis that IC is a distinct clinicopathologic entity with characteristic imaging features. We report the case of a 34-year-old Caucasian male presenting with intense unilateral neck pain in the emergency setting. Computed tomography and ultrasonography revealed fusiform eccentric thickening of the ipsilateral carotid bifurcation without vessel narrowing. Contrast-enhanced magnetic resonance imaging depicted major perivascular enhancement without evidence of dissection. Further imaging and laboratory work-up excluded vasculitis. The diagnosis of IC was made. The patient was treated with nonsteroidal anti-inflammatory drugs and symptoms and imaging findings disappeared within a few weeks. Cross-sectional imaging allows not only ruling out IC mimickers but also making the correct diagnosis of this rare condition, in particular, as the clinical presentation of IC is often nonspecific.

AbstractThere has been significant increase in the detection of incidental pancreatic lesions due to widespread use of cross-sectional imaging like computed tomography and magnetic resonance imaging supplemented with improvements in imaging resolution. Hence, accurate diagnosis (benign, borderline, or malignant lesion) and adequate follow-up is advised for these incidentally detected pancreatic lesions. In this article, we would review the various pancreatic parenchymal (cystic or solid) and ductal lesions (congenital or pathological), discuss the algorithmic approach in management of incidental pancreatic lesions, and highlight the key imaging features for accurate diagnosis.

Although peritoneal carcinomatosis is the most common entity involving the peritoneum diffusely, a vast array of unusual diseases may affect the peritoneal surfaces. These entities can be further categorized into infectious, neoplastic, and miscellaneous conditions. Cross-sectional imaging, including computed tomography and magnetic resonance imaging are excellent modalities for further characterization of these unusual diseases. For some of these conditions, imaging-specific diagnosis is achievable. For others, the diagnosis can be favored when clinical and/or cross-sectional imaging features coexist.

This article focuses on the cross-sectional imaging spectrum of abnormalities that affect the abdominal wall, with emphasis on magnetic resonance imaging (MRI). Cross-sectional imaging is valuable for diagnosing and evaluating the extent of abdominal-wall masses. With the increasing use of MRI, it is often possible to reach a diagnosis or narrow the differential diagnosis, thereby guiding effective management. Neoplastic and non-neoplastic pathologies will be illustrated, and the distinctive imaging characteristics of these entities will be highlighted.

AbstractAutoimmune pancreatitis (AIP) is a pancreatic phenotype of IgG4-related systemic disease. Since its first description in the literature, characteristic imaging features have gradually become known to many clinicians encompassing various specialties in the past quarter century. CT and MRI have been the workhorses for imaging diagnosis of AIP. Typical features include sausage-like swelling of the focal or entire pancreas, duct-penetrating sign, a capsule-like rim of the affected lesions, and homogeneous delayed enhancement or enhanced duct sign after contrast administration, as well as characteristic combined findings reflecting coexisting pathologies in the other organs as a systemic disease. In this review, recent and future developments in CT and MRI that may help diagnose AIP are discussed, including restricted diffusion and perfusion and increased elasticity measured using MR.
