Pulmonary aspergilloma: a potential cause of false positive fluorodeoxyglucose positron emission tomography scan.
Summary of "Pulmonary aspergilloma: a potential cause of false positive fluorodeoxyglucose positron emission tomography scan."
Pulmonary aspergilloma is a fungus ball developed in a pre-existing lung cavity, generally in the superior lobes. Its size remains stable in most cases and it is usually asymptomatic. Herein, we present a case of a 64-year-old male with pulmonary aspergilloma, which was developed in an emphysematous cyst of the right inferior lobe, increased in size, and fluorodeoxyglucose positron emission tomography scan was positive. There are only a few reported cases of pulmonary aspergilloma with a false positive fluorodeoxyglucose positron emission tomography scan.

Medical and Biotech [MESH] Definitions
The compound is given by intravenous injection to do POSITRON-EMISSION TOMOGRAPHY for the assessment of cerebral and myocardial glucose metabolism in various physiological or pathological states including stroke and myocardial ischemia. It is also employed for the detection of malignant tumors including those of the brain, liver, and thyroid gland. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1162)
An imaging technique using compounds labelled with short-lived positron-emitting radionuclides (such as carbon-11, nitrogen-13, oxygen-15 and fluorine-18) to measure cell metabolism. It has been useful in study of soft tissues such as CANCER; CARDIOVASCULAR SYSTEM; and brain. SINGLE-PHOTON EMISSION-COMPUTED TOMOGRAPHY is closely related to positron emission tomography, but uses isotopes with longer half-lives and resolution is lower.
False Positive Reactions
Positive test results in subjects who do not possess the attribute for which the test is conducted. The labeling of healthy persons as diseased when screening in the detection of disease. (Last, A Dictionary of Epidemiology, 2d ed)
Pulmonary Heart Disease
Hypertrophy and dilation of the RIGHT VENTRICLE of the heart that is caused by PULMONARY HYPERTENSION. This condition is often associated with pulmonary parenchymal or vascular diseases, such as CHRONIC OBSTRUCTIVE PULMONARY DISEASE and PULMONARY EMBOLISM.
Event-related Potentials, P300
A late-appearing component of the event-related potential. P300 stands for a positive deflection in the event-related voltage potential at 300 millisecond poststimulus. Its amplitude increases with unpredictable, unlikely, or highly significant stimuli and thereby constitutes an index of mental activity. (From Campbell, Psychiatric Dictionary, 6th ed)
