False Positive Radioiodinated Metaiodobenzylguanidine (123I-MIBG) Uptake in Undifferentiated Adrenal Malignant Tumor
(123)I-Metaiodobenzylguanidine ((123)I-MIBG) scintigraphy is a widely used functional imaging tool with a high degree of sensitivity and specificity in diagnosis of pheochromocytoma. However, rare cases of false positive reactions have been reported. A 67-year-old male patient was admitted with epigastric pain. Abdominal computed tomography (CT) revealed a heterogeneous left adrenal mass 6 cm i...
متن کاملMyocardial iodine-123-metaiodobenzylguanidine (123I-MIBG) imaging in Brugada syndrome.
(I-MIBG) Imaging in Brugada Syndrome To the Editor: We read with interest a recent article in Circulation by Wichter et al1 on cardiac autonomic dysfunction in Brugada syndrome. The authors demonstrated that regionally reduced iodine-123-metaiodobenzylguanidine (I-MIBG) uptake in the inferior and septal left ventricular wall was present in 8 (47%) of 17 patients with Brugada syndrome but in non...
متن کاملPulmonary Endothelial Impairment During Gefitinib Therapy: A Preliminary Assessment with Iodine-123-Metaiodobenzylguanidine (123I- MIBG) Scintigraphy
Iodine-123-metaiodobenzylguanidine ( 123 I-MIBG) kinetics in the lung could serve as a novel diagnostic tool to evaluate endothelial damage. Interstitial lung disease (ILD) associated with gefitinib, an epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI), has been reported as a serious adverse effect. This study was performed to examine the possibility that gefitinib induces...
متن کاملExtracutaneous infantile haemangioma is also Glut1 positive.
AIM To investigate whether extracutaneous infantile haemangioma-like tumours are immunohistochemically similar to cutaneous infantile haemangiomas. METHODS Mammary, salivary gland, liver (one each), and placental (two cases) capillary haemangiomas and typical examples of cutaneous (eight cases) infantile haemangioma were investigated immunohistochemically for alpha smooth muscle actin and Glu...
متن کاملFalse-positive accumulation of metaiodobenzylguanidine in a case with acute intermittent porphyria.
We report a 36-year-old woman presenting with hypertensive encephalopathy followed by bulbar palsy and quadriplegia. After an extensive screening for secondary causes of hypertension, the patient was suspected of having pheochromocytoma due to increased levels of catecholamines in the plasma and the urine, and positive (131)I-metaiodobenzylguanidine (MIBG) accumulation in the gallbladder. Howev...
