PURPOSE To report the development of a cavitary choroidal melanoma in a patient with nevus of Ota and describe its magnetic resonance imaging (MRI) features. PATIENT A 66-year-old man with right oculodermal melanocytosis and an ipsilateral choroidal cavitary melanoma was seen. Diagnosis was suspected on the clinical, ultrasonographic and MRI findings. RESULTS T1-weighted image showed a hype...

Cystic and cavitary lung lesions constitute a spectrum of pulmonary diseases diagnosed in both children and adults. Cysts and cavities are commonly encountered abnormalies on chest radiography and chest computed tomography. High-resolution computed tomography (HRCT) of the chest frequently helps define morphologic features that may serve as important clues regarding the nature of cystic and cav...

Pulmonary infections by Sporothrix spp. manifest radiologically as cavitary or non-cavitary disease depending on whether the infection is primary pulmonary or multifocal sporotrichosis. Despite current guidelines, the optimal management for pulmonary sporotrichosis remains unclear. In order to clarify this, we present two cases of pulmonary sporotrichosis, as well as the results of a comprehens...

OBJECTIVE Mycobacterium tuberculosis infects more than one-third of the world's population and causes an estimated 2-3 million deaths annually. The medical treatment of multidrug-resistant tuberculosis (MDR-TB) can cure 50-75% of cases. The median prevalence of new MDR-TB cases is 1.1%, while that of previously treated cases is 7%. METHODS We carried out a retrospective study on 45 patients w...

Background. Extrapulmonary tuberculosis (EPTB) accounts for >20% of tuberculosis (TB) cases in low TB incidence countries. Unlike pulmonary TB, diagnosis of EPTB is difficult due to atypical presentation and low culture positivity due to lower bacterial load. This study evaluated the performance of Xpert MTB/RIF (Xpert) and ProbeTec ET (PTec-ET) assays in diagnosing EPTB. Methods. A total of 16...

Dragica PEŠUT Teaching Hospital of Pulmonology Clinical Center of Serbia Dr Koste Todorovića 26 11000 Belgrade Serbia [email protected] SUMMARY Introduction Tuberculosis patients are rarely asymptomatic. Acute virus myocarditis presents with a wide range of symptoms, from mild dyspnea or chest pain to cardiogenic shock and death. Case Outline A 26-year-old Caucasian man non-smoker pre...

OBJECTIVES Multidrug-resistant tuberculosis (MDR-TB), defined as tuberculosis resistant to at least isoniazid and rifampicin in vitro, poses a significant challenge to the control of TB worldwide. Despite global efforts to control tuberculosis, it remains the leading cause of death from an infectious agent. Although modern tuberculosis treatment relies on chemotherapy, surgery is accepted as ad...

BACKGROUND Pulmonary artery aneurysms constitute <1% of aneurysms occurring in the thoracic cavity. Congenital cardiac defects are responsible for the majority (>50%) of cases, however, pulmonary artery aneurysm is a rare sequelae of pulmonary tuberculosis reported in about 5% of patients with chronic cavitary tuberculosis on autopsy. The natural history of this potentially fatal condition rema...

The primary objective of this study was to determine whether there is any hazard in the use of irradiation to the thorax for neoplastic disease coexistent with pulmonary tuberculosis. The association of lung cancer and pulmonary tuberculosis has become a problem of much significance. There has been in recent years a striking increase in lung cancer incidence and mortality. Tuberculosis which he...
