Diagnosis of pheochromocytoma can be simple when classic manifestations are present. It can also be challenging and complicated in some cases because of its wide array of faces and presentations. We present a case of a 30-year-old female patient who came with acute respiratory distress, chest pain, hemoptysis, asthenia, anorexia, weight loss of 20kg, and paresthesia in her lower limbs. Clinical examination found high blood pressure, accelerated heart and respiratory rates, signs of acute right heart failure with jugular venous distention and ankle edema, reticularis livedo in the four limbs, ulcers in both knees and in the 3rd metacarpo-phalangeal articulations and necrotic lesions in both calcaneal tendons and in the right toes. Further investigations concluded on myocarditis associated with alveolar hemorrhage, pericardic and pleuritic effusions and a segmental pulmonary embolism of the right inferior lobe. Neuro-muscular biopsy was suggestive of myositis. Cutaneous biopsy found nonspecific chronic dermatitis. ANCA antibodies were tested twice and were negative. Cryoglobulinemia was also negative. Thoraco-abdomino-pelvic scan was performed showing a large right adrenal mass suggestive of pheochromocytoma. Diagnosis of right adrenal pheochromocytoma was confirmed by MIBG-I123 hyperfixation findings and urinary normetanephrin levels. The patient was treated surgically. Postoperative outcomes were remarkably favorable with a complete regression of the cutaneous lesions and normalization of the blood pressure. Paresthesia significantly decreased. Control echocardiography at 3 months showed an improved heart function with a persistent apical and septal akinesis.

[Characteristics of cardiac involvement in eosinophilic granulomatosis with polyangiitis].

Aim Of The Study: Our study aimed to identify the characteristics of cardiac involvement in eosinophilic granulomatosis with polyangiitis (EGPA).

Methods: We conducted a retrospective analytic study including EGPA cases diagnosed between 2000 and 2019 in an internal medicine department. Diagnosis was made according to the 1990 American College of Rheumatology criteria and the 2012 Chapel Hill Concensus.

Results: Eleven EGPA cases were included, 64% of patients were female. Median age at diagnosis was 52 years [42-58]. Heart damage revealed EGPA in 55% of cases with a significant predominance of women (p=0.015). The main cardiac manifestations were myocarditis, ischemic cardiomyopathy due to small vessel vasculitis, cardiac tamponade and intracardiac thrombus. Cardiac magnetic resonance imaging (MRI) mainly showed subendocardial hyposignal in early infusion and late enhancement in the same areas, nodular by locations, associated with impaired left ventricle function and micro-infarctions by distal vasculitis. Cardiac damage was associated to ANCA negativity in 83.3% of cases. The median Birmingham Vasculitis Activity Score version3 (BVAS v3) was 16 [10-17]. Under conventional treatment, no relapses had occurred. The median vasculitis damage index (VDI) was 2 [1-2.3] and the mortality rate was zero after a mean follow-up of 43 months.

Conclusion: Cardiomyopathy is a frequent revealing mode of EGPA. A late onset asthma and hypereosinophilia should guide the diagnosis. As ANCA research often turns out to be negative, histological evidence is recommended in this context. The contribution of cardiac MRI in the diagnosis of EGPA remains to be defined.
