Abstract
Summary
A cavity is an air containing area within the lung surrounded by
consolidative wall which is at least 4 mm in thickness .Cavity may also
contain blood ,pus ,fluid or debris .Cavities are commonly encountered
lesions in the lung discovered during chest radiography and chest CT .
All cavitary lung lesions include wide variety of pulmonary diseases
such as infection (bacterial, fungal, parasitic), neoplastic, congenital ,airways
and collagen diseases .
Computed tomography provides a useful diagnostic information in the
evaluation of cavitary lung diseases as it can define the distribution of the
cavities, characterization of the cavity wall and abnormalities in the
surrounding lung parenchyma. In many cases, CT allows a confident
specific diagnosis of the cavitary lung lesions.
The aim of this study was to clarify the role of multi-detector
computed tomography in evaluation of cavitary lung lesions.
The present work included 60 patients with cavitary lung lesions. They
were 46 males and 14 females. Their ages ranged l5years and 83years. With
their mean age of 50 years old.
All patients were subjected to radiological examination including chest
X ray and 16 slice multidetector CT scanner.
In this study there were 10 patients with airway diseases, 35 patients
with infective lesions, and another 15 patients with tumors. The diagnosis
was confirmed by (clinical follow-up, needle biopsy or bronchoscopy).
