[A case of angioimmunoblastic T-cell lymphoma with interstitial shadow which disappeared after injection of hydrocortisone].

A case of angioimmunoblastic T-cell lymphoma (AITL) was reported. A 56-year-old woman was admitted because of high fever and systemic lymphademopathy. Her chest X-ray on admission showed mediastinal and bilateral hilar lymphademopathy (BHL) and interstitial shadows in both lower lung fields. Chest CT scan revealed thickening of interlobular septum and bronchovascular bundles. There was a remarkable elevation in serum soluble interleukin-2 receptor. A biopsy of cervical lymph nodes for histopathological examination revealed AITL. After intravenous injection of 200mg of hydrocortisone for 7 days, the interstitial shadows and BHL disappeared. It was suspected that interstitial shadow was caused by pulmonary infiltration of AITL.
