Disseminated tuberculosis with and without a miliary pattern
on chest radiograph: a clinical-pathologic-radiologic correlation.
These can be solitary, multifocal or in a miliary pattern
Chest imaging showed a diffuse infiltrate in a miliary pattern
HRCT shows a miliary pattern
of innumerable tiny nodular densities in both lungs.
The miliary pattern
is a well-known chest radiographic pattern, consistent with the multiple nodules in the lung.
The middle and lower lung zone involvement, bilateral lung involvement, miliary pattern
and normal chest radiograph were also more common in CD4 count <200/ [mm.
The predominance of miliary nodules in relation to cephalocaudal axis, their margin and size are not helpful features to the differential diagnosis of diseases presenting with a miliary pattern
Bilateral spontaneous pneumothorax in a patient with miliary pattern
23,24] Often the patient is treated for presumed bacterial pneumonia,[5-8,11,16] and the presence of the miliary pattern
can lead to a misdiagnosis of tuberculosis.
44 (62%) of the 71 patients with no underlying disease had a nodular pattern, 11 (15%) had confluent consolidation, 13 (18%) had consolidation with associated loss of volume and 3 (4%) patients had miliary pattern
The diagnosis of TB was confirmed in 25 patients, 19 of whom had positive cultures (gastric washings/ sputum, blood or aspirate) and/or granulomas on histology (Table 1), while 6 patients were classified as having probable TB and treated as such, based on clinical suspicion and miliary pattern
on chest X-ray, but in the absence of laboratory confirmation.
