Nonneoplastic Tracheal Abnormalities on CT
Tracheal disorders can create clinical and imaging challenges. They are often misdiagnosed as other pulmonary disorders. Chest radiography has low sensitivity and specificity for proper identification of tracheal disorders. Multidetector-row CT (MDCT) has the inherent advantage of being able to provide high-quality multiplanar reformations, 3D volume-rendered images, virtual bronchoscopy, and minimum intensity projections. These can serve as a roadmap for bronchoscopy or surgical planning. The most important imaging sign of tracheal disease is thickening of the tracheal wall, and the most relevant sign to be evaluated for ...

Direct intraoperative cholangiography, endoscopic retrograde cholangiopancreatography, T-tube cholangiography, and percutaneous transhepatic cholangiography are routine procedures performed by interventionalists. Radiologists must understand how to interpret direct cholangiography to facilitate multidisciplinary communication, correlate findings with magnetic resonance cholangiopancreatography, and improve patient care.

Neurologic Complications of Immunotherapy
Immunotherapy enhances a patient's own immune system to fight against malignancy and has become increasingly popular during the last decade. Tumor cells can escape destruction by the patient's immune system by overexpression of immunosuppressive molecules such as cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4), programmed cell death-1 (PD-1) receptor, and its ligand PD-L1. Immunotherapy agents target these inhibitors and basically reactivate the cytotoxic lymphocytes to destroy the tumor cells. Immunotherapy agents currently are FDA-approved for advanced malignancies including melanoma, Hodgkin lymphoma, head and neck...

Imaging Pseudotumors of the Shoulder
Normal variants and benign pseudotumors are common findings on imaging throughout the body. Pseudotumors of the shoulder are common discoveries on routine and emergent shoulder imaging examinations that can create diagnostic conundrums for the radiologist (Table 1). As the volume of medical imaging continues to increase, knowledge of these findings will be essential for accurate diagnosis. Misdiagnosis of a pseudotumor may lead to patient anxiety, unnecessary procedures, surgery, or other medical treatment. (Source: Contemporary Diagnostic Radiology)

The Swollen Parotid Gland
Several systemic diseases and local inflammatory processes can cause diffuse enlargement of the parotid gland. Clinical information regarding the patient's age, localization (including laterality), duration, clinical course of the disease, and presence of associated symptoms can aid in determining the diagnosis. CT and MRI features that help narrow the differential diagnosis include the appearance of the gland (homogeneous, single, or multiple masses); inflammatory changes in, or adjacent to, the parotid gland; pattern of disease spread to adjacent spaces; and the presence of lymphadenopathy. In some cases, imaging is used...

Acute Small Bowel Pathology: Spectrum of Nonneoplastic Diseases on CT
Acute abdomen with clinical suspicion of small bowel pathology is a common indication for CT imaging. Acute processes may result from a variety of entities, including infectious, noninfectious inflammatory, neoplastic, mechanical, iatrogenic, and vascular causes. However, CT imaging features of acute small bowel diseases often can overlap. Therefore, combining clinical history, laboratory data, and current and previous imaging features is key to accurate diagnosis. Familiarity with the various causes of acute small bowel pathology will allow the radiologist to help guide clinical management of patients. (Source: Contempora...

Bone Lesions of the Hand and Wrist: Systematic Approach to Imaging Evaluation
Hand and wrist bone lesions comprise a special subset of masses. When evaluating these lesions, relative tumor incidence always should be considered. For bone lesions occurring throughout the body, the incidence of primary bone tumors is much lower than that of nonneoplastic bone diseases, metastatic diseases, and hematolymphoid malignancies.1 In the hand, benign bone lesions greatly outnumber malignant lesions, as highlighted in a published case series on hand and foot bone lesions.1 Of 52 bone lesions of the hands and feet evaluated with histopathology, the relative incidence was pseudotumors (38%), benign primary tumors...

A Diagnostic Approach to Various Fat-Containing Lesions in Thoracic Imaging
Fat-containing lesions may involve any compartment of the chest, and the differential diagnosis for these lesions primarily depends on location, imaging features, and patient demographics. Although many fat-containing lesions of the chest are benign, they may be manifestations of pathologic and malignant conditions. Therefore, interval growth of the lesions and any morphological changes of the adjacent structures over time also should be evaluated. (Source: Contemporary Diagnostic Radiology)

The breast is injured in a variety of circumstances, including direct trauma, such as from a motor vehicle accident, or iatrogenic, secondary to biopsy or intervention. The severity of reported breast injuries ranges from small hematomas to breast avulsion; the latter injury requires emergent mastectomy to stop active hemorrhage.1 The correlation of multimodality breast imaging with clinical presentation is important for differentiating benign posttraumatic abnormalities from malignant processes, thereby preventing unnecessary workup and intervention.

Acute intestinal obstruction is a common cause of morbidity in patients who present with an acute abdomen and accounts for 20% of admissions for “surgical abdomen.” Imaging is important in confirming the diagnosis and identifying the underlying cause. Safe and effective management depend on prompt and accurate diagnosis. Bowel obstruction is subdivided into small and large bowel obstruction, based on the site of luminal narrowing. The causative factors for the two subgroups are usually quite different. (Source: Contemporary Diagnostic Radiology)

Multiple Hereditary Exostoses: Genetics, Multimodality Imaging Features, Complications, Differential Diagnosis, and Treatment
Osteochondromas are a common type of benign bone tumor that occur during childhood. Osteochondromas can be solitary or multifocal as a part of a syndrome, known as multiple hereditary exostoses (MHE). This differentiation was first discovered in 1786 by John Hunter, a famous Scottish surgeon. In 1814, MHE was found to have a familial association. Later, in the 1900s, MHE was differentiated from other disorders, such as Ollier disease (multiple enchondromatosis) and Trevor disease (dysplasia epiphysealis hemimelica). MHE is known by other names including hereditary multiple osteochondromas, diaphyseal aclasis, hereditary de...

Emergencies that involve the soft tissues of the musculoskeletal system are common; however, these conditions often are difficult to differentiate clinically.1 Early detection and diagnosis have a significant impact on treatment. Although many disorders present with similar symptoms, some laboratory and constitutional findings are helpful in diagnosing specific diseases. MRI is well-established as the preferred imaging modality for evaluation of soft tissue disorders because of its excellent contrast resolution, sensitivity for pathologic fluid accumulation, and depiction of abnormal tissue compartments; thus, recognizing ...

A pathologic fracture is a fracture of an abnormal bone weakened by an underlying disease, thus it requires careful assessment. Pathologic fractures may occur in benign lesions, primary and secondary malignancies, and a variety of metabolic disorders. A nontraumatic fracture, a fracture with minor trauma, and multiple contiguous fractures suggest a pathologic nature. In these cases of pathologic fractures, evaluation by advanced imaging modalities, including CT, MRI, and PET-CT, often reveals more significant findings. Accurately identifying and characterizing pathologic fractures on imaging are paramount for guiding prope...
