An unusual case of active tuberculosis of the oesophagus in an adult

Eosinophilic oesophagitis and other non-reflux inflammatory conditions of the oesophagus: diagnostic imaging and management

Non-reflux inflammatory conditions of the oesophagus are at present rarely encountered in routine clinical practice. However there has been a recent increase in their diagnosis notably due to heightened awareness of their existence and because of the emergence of a number of immunological diseases and deficiencies. Of all the non-reflux conditions, most interest and literature is emerging on the natural history, pathophysiology, endoscopic pattern and management of eosinophilic oesophagitis. This condition, which until five years ago was unknown to most physicians has now been studied worldwide and although the true prevalence remains unclear, the incidence is increasing annually. In this paper we discuss diagnostic imaging and management of non-reflux inflammatory disorders of the oesophagus with particular reference to eosinophilic oesophagitis and Crohn's disease, both conditions of probable over active immunology, to other conditions associated with immune deficiency such as infective oesophagitis (candida, CMV, HSV, HIV) and tuberculous oesophagitis, as well as drug induced oesophageal injury.

Tuberculous Lymphadenopathy Causing Dysphagia: Report of Two Cases

We report two cases of tuberculous lymphadenopathy causing dysphagia. The first patient was HIV positive and the second patient had immigrated recently from India. Culture in both patients grew Mycobacterium tuberculosis that was fully sensitive to first line drugs. Dysphagia may result from intrinsic or extrinsic involvement of the esophagus. Extrinsic involvement is more common and results from cervical and mediastinal lymph node enlargement (as in these 2 cases) that causes external compression on the wall of the esophagus. The dysphagia subsided completely after 4 weeks of antituberculous therapy in both cases.

Esophageal infections: risk factors, presentation, diagnosis, and treatment

Infections of the esophagus are unusual in the general population and strongly imply immunodeficiency, although immunocompetent individuals are not exempt. HIV infection is predominant among risk factors for infectious esophagitis. For all immunocompromised patients, the most frequently identified esophageal pathogens are Candida, CMV, and HSV. Peculiar to HIV-infected patients are idiopathic esophageal ulcers as well as unusual bacteria and parasites. Patterns of presentation differ with each infecting organism, and clinical features should be used as a guide in achieving a correct diagnosis. For example, a patient with AIDS presenting with esophageal symptoms and thrush, along with abdominal pain, nausea, vomiting, and fever, is unlikely to resolve all symptoms with empiric antifungal therapy alone. Parsimony of diagnosis does not hold among immunodeficient patients in whom concurrent infections are common. Accurate and timely diagnoses are essential as effective treatments are available for particular etiologies. Finally, among immunocompromised patients, all esophageal symptoms are not necessarily due to an infection, and possible diagnoses of pill esophagitis, acid-peptic injury, or structural and functional abnormalities should not be overlooked.
