We examined sputum bacterial loads in adults with newly diagnosed tuberculosis using quantitative culture and time-until-positive (DTP) culture in BACTEC 460. Patients with cavitary disease had higher CFU levels than those without cavities and shorter DTPs. Within radiographic strata of moderately and far advanced tuberculosis, higher CFU counts were associated with cavitary disease.

OBJECTIVE To assess the long-term results of chemotherapy for cavitary retinoblastoma. METHODS Retrospective, nonrandomized, interventional case series of 26 cavitary retinoblastomas in 25 eyes of 24 patients. Retinoblastomas were treated with intravenous chemoreduction and/or intra-arterial chemotherapy. Main outcome measures included tumor control, globe salvage, and metastasis. RESULTS O...

The goals of the present study were twofold: (i) to compare the repertoires of antigens in culture filtrates of in vitro-grown Mycobacterium tuberculosis that are recognized by antibodies from noncavitary and cavitary tuberculosis (TB) patients and (ii) to determine the extent of variation that exists between the antigen profiles recognized by individual TB patients. Lipoarabinomannan-free cult...

Pulmonary cystic and cavitary lesions caused by diverse etiologies are commonly encountered in chest imaging. The terms "cyst" and "cavity" are used to describe air-filled regions in the center of a nodule or consolidation of the lung. To date, only radiologic aspects of these lesions have been addressed. The morphologies of pulmonary cystic and cavitary lesions exhibit a broad spectrum, rangin...

A 47 year old woman developed idiopathic bronchiolitis obliterans organizing pneumonia (BOOP) presenting with haemoptysis and diffuse multiple cavitary nodules. The disease was histologically confirmed by open lung biopsy after other entities had been excluded. The patient responded to a course of corticosteroids. This BOOP should be added to the list of diseases with multiple cavitary nodules.

Pulmonary endometriosis is a rarely seen disease of the lung. On computed tomography, a cavitary lesion of 15 × 26 in size was detected in the lung parenchyma of a 38-year-old female patient who was examined due to hemoptysis. The pathologic result of the surgically excised cavitary lesion was reported as pulmonary endometriosis.

Reports of cavitary lung cancer are not uncommon, and the cavity generally contains either dilated bronchi or cancer cells. Recently, we encountered a surgical case of cavitary lung cancer whose cavity tended to enlarge during long-term follow-up, and was found to be lined with normal bronchial epithelium and adenocarcinoma cells.

We describe a patient with pulmonary cavitary pneumonia from whom we serially isolated Mycobacterium kyorinense, an organism not previously reported in Australia, or associated with cavitary disease. We discuss the clinical presentation, the isolation of the organism on several specimens and initial management. M. kyorinense is a recently characterized species, which has previously only been de...

The typical radiographical findings of cytomegalovirus pneumonitis are bilateral interstitial infiltrates. In this study, the current authors describe two patients on corticosteroid treatment for systemic lupus erythematosus, complicated by histologically confirmed cytomegalovirus pneumonitis, presenting as cavitary masses. This rare presentation of cytomegalovirus pneumonitis broadens the diff...
