“…Regardless of the etiology, this finding indicates an important systemic compromise that requires rapid therapeutic conduct, taking into In the presented case, the imaging findings indicated with a high degree of reliability the presence of a random miliary pattern. According to the data obtained, it was possible to establish that this pattern manifests itself in metastatic lung diseases in only 5% of patients 2,4,5 , and although this pattern has frequently been associated with tuberculosis, its radiological presentation is only seen in 1%-7% of cases 6 , while in histoplasmosis this finding can be seen in up to 55% of chest CT scans 7 .…”

The term "nodular pattern" refers to small and multiple nodular lesions in the lung parenchyma. The location of the nodules in relation to the structures of the secondary pulmonary lobule allows narrowing the differential diagnosis and categorizes the nodular pattern into perilymphatic, centrilobular and random. The random-type miliary pattern, although commonly linked to tuberculosis, is a radiological manifestation present in several conditions, highlighting fungal infections and metastases. Clinically, these conditions present similar and non-specific signs and symptoms, the histopathological study being the reference method for diagnosis. Radiographic findings depend mainly on the immune status of the host and the exposure load.
