Pneumonitis differential diagnosis

Suggested Alternatives for Differential Diagnosis Drug induced noncardiac pulmonary edema, acute respiratory distress syndrome, pneumonic plague, tularemia, Q fever, and viral influenza. 

Suggested Alternatives for Differential Diagnosis Bovine viral diarrhea/mucosal disease, rinderpest, bluetongue, foot and mouth disease, vesicular stomatitis, pneumonic pas-teurellosis, photosensitive dermatitis, infectious bovine rhinotracheitis, theileriosis, rabies, and the tick-borne encephalitides. 

Fig. 27.14. Three weeks after local radiation for a tumorous spine destruction, this patient suffered from fever and dyspnoea. Perihilar infiltrates appeared suddenly. Intralobular septa, consolidation, and ground-glass opacification were determined at HRCT. Especially the para-mediastinal distribution of the infiltrates led to the differential diagnosis of radiation pneumonitis. After failure of antibiotic escalation (chosen because of a concomitant abscess), steroids were applied additionally. This led to a quick improvement of the symptoms as well as reduction of infiltrates...

Table 2 Differential Diagnosis of Acute Interstitial Pneumonitis Acute eosinophilic pneumonia...

The differential diagnosis of LIP is low-grade marginal zone B-cell lymphoma of MALT (MALToma) and interstitial pneumonitides in the lung, including nonspecific interstitial pneumonitis and hypersensitivity pneumonitis (Table 2). 

The principal differential diagnosis is MALT lymphoma, lymphoid interstitial pneumonitis, and follicular hyperplasia of BALT. Pertinent features of the differential diagnosis are shown in Table 2. 

Vourlekis et al. (2002) has reported six cases of HP in which the pathological characteristics of surgical lung biopsies met the criteria for non-specific interstitial pneumonitis (NSIP). HP should be included in the differential diagnosis of NSIP made by lung biopsy. Patients with the histopatho-...
