Eagle syndrome occurs due to elongation of the styloid process or calcification of the stylohyoid ligament, which then may produce a pain sensation due the pressure exerted on various structures in the head and neck. When suspected, imaging helps in identifying the abnormally elongated styloid process or the calcified ligament. In recent years, three-dimensional CT (3DCT) has proved to be valuable in these cases. We report the case of a 62-year-old man with this syndrome in whom imaging with 3DCT conclusively established the diagnosis.

Bronchial anthracofibrosis (BAF), caused by long-standing exposure to biomass fuel smoke, has emerged as a distinct pulmonary disease. It is usually seen in elderly females who have worked long hours in poorly ventilated kitchen full of smoke due to incomplete combustion of biomass fuel. The diagnosis is confirmed on bronchoscopic visualization of bluish-black anthracotic pigmentation along with narrowing/distortion of the affected bronchus. BAF has been associated with clinical conditions such as pulmonary tuberculosis, chronic obstructive pulmonary disease, pneumonia, and malignancy. Tuberculosis, once thought to be the causative agent for BAF, is now considered to be an association. BAF has a diverse radiological presentation and the presence of associated clinical conditions often confound the radiological picture. The imaging features of BAF include primary imaging characteristics, which pertains to the disease entity directly, and secondary features based on the presence of associated conditions. High-resolution computed tomography findings of multifocal bronchial narrowing and peribronchial cuffing are considered to be specific diagnostic features of BAF. In addition, the diagnostic probability is increased in the presence of mediastinal adenopathy and collapse/atelectasis with middle lobe syndrome being the most common presentation. This pictorial essay highlights the range of imaging appearances in patients with BAF.

The autopsy incidence of internal hernia has been reported to be between 0.2% and 0.9%, and these hernias are usually diagnosed on imaging due to their complications or at surgery. Meckel diverticulum is the most common congenital anomaly of the gastrointestinal tract, occurring in 1% to 3% of the population according to autopsy studies. The condition also is usually diagnosed at surgery, by barium studies or scintigraphy, or on cross-sectional imaging due to complications. We present an unusual case of a large Meckel diverticulum in a right paracolic hernia diagnosed on multidetector computed tomography. This diagnosis was made after attacks of subacute intestinal obstruction with the aid of multiplanar reconstructions. This case emphasizes the role of multidetector computed tomography and postprocessing techniques such as multiplanar reconstruction in the diagnosis of bowel pathology.

Multi-detector computed tomography has become a first-line imaging modality for the evaluation of small bowel disease. Its high speed and resolution ensure excellent imaging of the small bowel with simultaneous evaluation of the lumen and wall, adjoining mesentery, and extraluminal structures in the abdominal cavity. Optimal luminal distension is an important prerequisite. Computed tomography enterography (CTE) is a dedicated adaptation for the study of the small bowel. This review discusses CTE with emphasis on procedural technique and image interpretation.

Tuberculosis is known to cause both cystic lung disease and bronchocentric granulomatosis (BCG). However, both are rare manifestations of this common disease. We report a case of BCG with extensive cystic lung disease in a young female who presented with fever, weight loss, and recurrent pneumothoraces with respiratory failure. Early diagnosis and treatment are imperative, as appropriate therapy may be life-saving in such cases.
