Diagnosis With Brief Discussion

Diagnosis: Angioimmunoblastic T-cell lymphoma
Radiologic Findings: Chest radiograph shows multiple nodules in both middle lung zones, right hilar enlargement, and hyperlucency and reticulation in both lungs.
CT scan demonstrates multiple lymph node enlargements with central low attenuation and peripheral well enhancement in paratracheal, subcarinal, hilar space. Well defined nodules and small area of consolidation are visible in RLL, LUL and LLL.
Brief Review: Angioimmunoblastic T-cell lymphoma is clinically characterized by a high fever, generalized lymphadenopathy, a skin rash, and hepatosplenomegaly. This is a relatively rare disorder but one that is clinically distinctive. It accounts for less than 1% of all non-Hodgkin lymphomas in Asia and Europe. Although this disorder has been regarded as an abnormal immune reaction (angioimmunoblastic lymphadenopathy with dysproteinemia or immunoblastic lymphadenopathy), it is now accepted as a subtype of PTCL. Because patients most commonly present with disseminated conditions, the imaging features are not distinguished from those in other lymphoma.
Primary pulmonary lymphoma cannot be distinguished from secondary pulmonary lymphoma solely on the basis of pathologic examination of pulmonary tissue only, because a variety of gross patterns of disease (solitary or multiple nodules, solitary infiltrate, or multiple infiltrates with or without hilar or mediastinal adenopathy) may be seen in either setting.
On chest radiographs, recurrent or secondary pulmonary lymphoma may present with various patterns: bronchovascuhar or lymphangitic with thickening of bronchovascular bundles and interlobular septae (41%), discrete pulmonary nodular (39%), pneumonic or alveolar with areas of consolidation (14%), and miliary or hematogenous with disseminated micronodules (6%). Lymphomatous infiltration of the alveoli can result in granuhomatous consolidation that may mimic the appearance of pneumonia or miliaiy tuberculosis. Lymphadenopathy and pleural effusions are also commonly present. Prevascular or pretracheal node involvement is seen most often. Other sites of lymph node involvement include the subcarinal, hilar,paraaortic, paravertebral, retrocrural nodes. Enlarged lymph nodes or mediastinal masses may appear low in attenuation due to necrosis.Other manifestations include cavitated masses and endobronchial masses.
Diagnosis is difficult because infection, granulomatous disease, primary or secondary carcinomas, or drug reactions may cause similar abnormal radiologic findings. Careful correlation of clinical, microbiologic, and histologic findings is necessary.
