Diagnosis With Brief Discussion

Diagnosis
Pulmonary lymphoma
Radiologic Findings
Fig 1. Chest PA shows mass-like consolidation in right lower and left upper lung zone.
Fig 2-5. CT scans reveal multifocal mass-like spiculated consolidation with peripheral ground glass opacity in both lungs. The consolidations showed homogeneous enhancement (average 70-80 HU) and air bronchogram. There were also multifocal small peribronchovascular nodules in both lungs. There were no significantly enlarged lymph nodes in the mediastinum nor pleural effusion.
Brief Review
Primary pulmonary lymphoma (PPL) represents a monoclonal lymphoid proliferation affecting the lungs in a patient with no detectable extrathoracic lymphoma for at least 3 months after the initial diagnosis. PPL ranges from a relatively indolent MALT lymphoma to more aggressive forms of diffuse large B-cell lymphoma. These two entities make up the majority of cases of PPL, which is overall a rare disorder. Non-Hodgkin B-cell lymphoma (NHL-B) is the most frequent type and accounts for roughly 80% of all PPL. The majority of these are MALT lymphomas, which are frequently associated with autoimmune diseases. DLBCL accounts for the majority of the other patients with PPL and it is characteristically seen in patients with underlying immunodeficiency, such as transplant patients on ciclosporin. The incidence of DLBCL may well be underestimated, as it could potentially spread rapidly from the lung into mediastinal and extrathoracic locations.
MALT lymphomas are usually asymptomatic and discovered as an incidental findings. They are typically indolent lesions and have a good prognosis. Immunocompromised patients with DLBCL are usually symptomatic with dyspnea, fever, and weight loss. Overall survival is poor and the prognosis is worse if there is an underlying disorder. Progression and relapse also occur much earlier in this group. DLBCL tends to be more diffuse and destructive, with 5-year survival rates ranging from 0
