Schwannoma and Paraganglioma: Rare Causes of Pancoast Tumors with Increased FDG Uptake on PET/CT

Year 2016, Volume: 38 Issue: 2, 62 - 65, 22.01.2016

Abstract

Pancoast tumors are the masses that are located at the apical region of the lungs and may cause some typical symptoms, named as Pancoast Syndrome, like shoulder and arm pain, Horner’s syndrome (ipsilateral ptosis, myosis, enophthalmus and anhydrosis) and weakness in ipsilateral hand musculature due to the invasion of the adjacent nerves and bone. These tumors are commonly the malign lung carcinomas. Here we report two cases of patients suffering from back and arm pain and that have some pancoast syndrome symptoms mentioned above, related to apical mass in radiological images. One of these patients had ptosis and anhydrosis associated with Horner's syndrome. 2-Deoxy-2-[18F] Fluoro-D-Glucose (FDG) with positron emission tomography/computerized tomography (PET/CT)was performed because of a suspicion of malignancy and an intense FDG accumulation was seen coincident with the apical tumor in both. The patients then underwent complete surgical resection of the mass and the masses were postoperatively diagnosed as paraganglioma and schwannoma, respectively. So, we wanted to emphasize that neurogenic tumors should be included in the differential diagnosis of Pancoast tumor as a rare cause and to remind the clinicians to give their attentions for essentiality of tissue diagnosis of Pancoast carcinoma before starting the treatment.

PET/CT GÖRÜNTÜLEMEDE ARTMIŞ FDG TUTULUMU GÖSTEREN NADIR PANKOAST TÜMÖRÜ NEDENLERINDEN SCHWANNOMA AND PARAGANGLIOMA

Abstract

Pankoast tümörleri omuz ve kol ağrısı, Horner Sendromu (ipsilateral ptozis, myozis, enoftalmus ve anhidrozis ) ve komşu sinir ve kemik yapılarının invazyonuna bağlı aynı taraf el kaslarında güçsüzlük gibi bazı tipik semptomlara, Pankoast Sendromu olarak isimlendirilir, neden olabilen akciğerlerin apikal kesimlerinde yerleşim gösteren kitlelerdir. Biz burada radyolojik görüntülemelerinde apikal kitlesiyle ilişkli sırt ve kol ağrısı tarifleyen ve yukarıda belirtilen bazı pankoast sendromu bulguları mevcut olan iki vakayı bildirdik. Hastalardan birisinin Horner Sendromuı ile ilişkili ptozis ve anhidrozisi vardı. İki olguda da 2-Deoxy-2-[18F] Fluoro-DGlucose (FDG) with positron emission tomography/computerized tomography (PET/CT) malignite şüphesiyle yapıldı ve apikal yerleşimli kitlelerde yoğun artmış FDG akümülasyonu izlendi. Hastalar opere edildi ve çıkarılan kitleler paraganglioma ve schwannoma olarak raporlandı. Bu olgularla nörojenik tümörlerin Pankoast tümörleri ayırıcı tanısında nadir nedenler arasında akılda bulundurulması gerektiğini vurgulamak ve Pankoast karsinomunun tedavisine başlamadan önce doku tanısının gerekliliği konusunu klinisyenlere hatırlatmak istedik.
