ABSTRACT
18F-fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET-CT) is a rapidly evolving hybrid imaging technique in evaluation of infection and inflammation. Usually, functional changes often precede anatomical changes. 18F-FDG PET-CT, a noninvasive diagnostic test and it is useful for the early detection of inflammation. Most of the large vessel vasculitis patients present with nonspecific signs and symptoms, which are difficult to diagnose clinically. Here, we discuss three cases of large vessel vasculitis with different clinical presentations, identified by 18F-FDG PET-CT scan.
ABSTRACT
Bone scintigraphy (BS) is a well--established commonly used imaging modality for staging and follow--up evaluation of cancer patients. Occasionally, BS may show asymptomatic unusual extraosseous lesions in the body which may or may not be related to primary disease. We here present an interesting case of carcinoma cervix in whom 18F sodium fluoride positron emission tomography-computerized tomography (PET-CT) bone scan detected an intracranial lesion. Initially, this lesion was suspected as brain metastasis; however, later on, combined PET--CT images and contrast-enhanced CT confirmed this lesion as calcified falcine meningioma in the right posterior parietal region.
ABSTRACT
BACKGROUND: Incidence of multiple primary cancers though uncommon, is being frequently reported now-a-days owing to better diagnostic techniques, the prolonged life span and the increased incidence of long-term survival of cancer patients. MATERIALS AND METHODS: This is a retrospective study. Cases of multiple malignancies diagnosed histopathologically were retrieved from the archives of department of surgical oncology. Clinical data were obtained from the medical records. They were categorized as synchronous malignancies if the interval between them was less or equal to 6 months and metachronous, if the interval was more than 6 months. RESULTS: A total of 13 cases were encountered in the 5 year study period. Out of them two were in the metachronous category and the rest were synchronous as the 2(nd) malignancy was detected mostly during clinical evaluation of the patients for the primary malignancy. There was female predominance with age range being 43-68 years. Majority of the cases were in the 7(th) decade. The most common organ involved was breast, followed by cervix. Apart from bilateral breast malignancies, there were combinations like breast with uterine endometrial carcinoma, cervical carcinoma and even papillary thyroid carcinoma. CONCLUSION: Detection of multiple primary malignancies is becoming increasingly common in day-to-day practice. Greater awareness of this is required among both cancer patients and their treating clinicians.
ABSTRACT
Minor musculoskeletal injuries usually heal within few weeks with conservative treatment, but in pelvic injuries, symptoms may persist for long duration and patient need medical attention to get relief from disturbing pain symptoms. We present a case of post-trauma osteitis pubis in a 58-year-old female, who reported with lower abdominal and left side hip joint pain since 2 months, after an episode of trivial trauma to her pelvis. Technetium-99m methylene diphosphonate bone scintigraphy was performed, which confirmed the site of injury in symphysis pubis and left hip joint, by increased radiotracer localization at both of these symptomatic sites.

AIM: : To determine whether gadolinium-enhanced three-dimensional magnetic resonance angiography can provide a noninvasive alternative to diagnostic catheterization for evaluation of pulmonary artery anatomy in tetralogy of Fallot. PATIENTS AND METHODS: Thirty-five consecutive patients with tetralogy of Fallot, who attended the cardiology outpatient department between January 2008 and December 2009, were included in the study. There were 21 males and 14 females, with a mean age of 9 ± 4.15 years (range, 3-21 years). Thirty-two patients had tetralogy of Fallot with varying severities of valvular and infundibular stenosis. Three patients had tetralogy of Fallot with pulmonary atresia. All patients underwent both cardiac catheterization with X-ray angiography and 3-dimensional magnetic resonance angiography within one month. RESULTS: Measurements of right and left pulmonary arteries and aortopulmonary collaterals were equal by both methods. There was a good correlation between magnetic resonance angiography and catheterization measurements of branch pulmonary arteries. CONCLUSION: Gadolinium-enhanced three-dimensional magnetic resonance angiography can be used as a reliable noninvasive alternative to X-ray cineangiography for delineation of pulmonary arterial anatomy in sick infants and young children, obviating the need for catheterization.
