Rosai and Dorfman Disease with Pleural Involvement: Case Report

Sinus histiocytosis with massive lymphadenopathy (SHLM) disease is considered to be an indolent and self-limiting pathology. However, severe morbidity and mortality have been attributed to complications of SHLM. Lower respiratory tract involvement is rarely reported and is often unfavorable, and carries a particularly grave prognosis. A case of SHLM is reported, in which the patient had lower respiratory and pleural involvement.

Une pleuro-pneumopathie droite fébrile excavée

Resume Les manifestations pleuro-pulmonaires au cours de la pyonephrose sont rares. Les auteurs rapportent un nouveau cas revele par une pleuro-pneumopathie febrile avec pleuresie purulente a Escherichia coli . L’echographie abdominale et la tomodensitometrie ont permis de redresser le diagnostic.

Respiratory Tract Vasculitis

The respiratory airway and pulmonary parenchyma are frequently involved in vasculitis particularly in small-vessel vasculitis associated with antineutrophil cytoplasmic antibodies. The diagnosis is based on anamnesis and physical examination but remains largely dependent on high-resolution CT and angiography. The confirmation of diagnosis depends on tissue biopsy. Conventional chest radiography is usually not very contributive. High-resolution CT is more sensitive in showing the spectrum of thoracic manifestations but it is nonspecific. MRI and MR angiography can provide information on vessel wall thickening in the early stage and on luminal changes. PET/CT is a good indicator of inflammation and helpful for follow-up.
