- Pheochromocytoma presenting with remote bony recurrence twenty years after initial surgery: detection with 68Ga-DOTANOC PET/CT.
- Parida GK1, Dhull VS, Sharma P, Bal C, Kumar R.Author information 1From the Department of Nuclear Medicine, All India Institute of Medical sciences, New Delhi, India.AbstractPheochromocytomas are rare tumors which can be malignant in 10% of cases. We present the case of a 75-year-old woman who presented with headache and palpitation for 1 year. She had a past history of right adrenalectomy for pheochromocytoma 20 years back. In between, the patient was asymptomatic. Twenty-four-hour urinary vanillylmandelic acid was raised. Noncontrast CT and ultrasound of abdomen were unremarkable. The patient underwent 68Ga-DOTANOC PET/CT that showed metastasis to left ilium, which was confirmed on biopsy.

- Monoamine metabolites in ventricular CSF of children with posterior fossa tumors: correlation with tumor histology and cognitive functioning.
- Varela M1, Alexiou GA, Liakopoulou M, Papakonstantinou E, Pitsouni D, Alevizopoulos GA.Author information 1Department of Neurosurgery.AbstractObject The biogenic amines (dopamine, epinephrine, norepinephrine, and serotonin) are involved in the regulation of multiple neuronal functions, and changes in monoamine concentrations in the CSF have been detected in several disorders. The aim of the present study was to investigate the role of biogenic amines in the ventricular CSF of children suffering from posterior fossa tumors and their possible correlation with tumor histology and cognitive functioning. Methods Twenty-two children with posterior fossa tumors who were treated surgically at Children's Hospital "Agia Sofia" were studied. Patients ranged in age from 5.5 to 15 years. The study population included patients who suffered from hydrocephalus and were treated by ventriculoperitoneal shunt placement. During the operation for shunt placement, a CSF sample was obtained for the assessment of 3-methoxy-4-hydroxyphenylglycol (MHPG), homovanillic acid (HVA), and 5-hydroxyindoleacetic acid (5-HIAA). Simultaneously, a blood sample was also obtained for assessment of the same metabolites in the serum. The concentration of vanillylmandelic acid (VMA) was evaluated in 24-hour urine samples in 11 patients. Cerebrospinal fluid from a control group of children was also studied. Executive functions were assessed using the short form of the Wechsler Intelligence Scale for Children (WISC). Results Twelve patients suffered from astrocytomas, 9 from medulloblastomas, and 1 from an ependymoma. The MHPG concentration in CSF was significantly higher in patients with astrocytomas compared with patients with medulloblastomas. Twenty-four-hour urine samples of VMA were significantly higher in patients with astrocytomas compared with patients with medulloblastomas. The MHPG concentration in CSF was negatively correlated with the verbal scale of the WISC and there was a trend toward a significant negative correlation with the total WISC score. Homovanillic acid in CSF was positively correlated with the performance scale of the WISC. There was a significant correlation between HVA and MHPG levels in CSF. The CSF concentration of 5-HIAA was significantly correlated with the HVA concentration in serum. Twenty-four-hour urine VMA samples were statistically significantly correlated with HVA concentration in both CSF and serum, with MHPG in CSF, and with 5-HIAA in serum. Conclusions This study showed that children with posterior fossa tumors have differences in the levels of monoamine metabolites in CSF. Further studies with a larger number of patients are obviously needed to verify these observations as well as studies to correlate the monoamine metabolite levels with the neuropsychological and behavioral findings in children with posterior fossa tumors.

- Diagnostic Challenge of Pheochromocytoma in a Patient Receiving Levodopa for Parkinson's Disease.
- Shimodaira M, Niwa T, Nakajima K, Kobayashi M, Shimodaira M, Niwa T, Nakajima K, Kobayashi M.Author information The Department of Internal Medicine, Iida Municipal Hospital, Nagano, Japan.AbstractObjective The diagnosis of pheochromocytoma in patients receiving levodopa is challenging because the standard diagnostic biochemical tests are considered to be confounded by dopaminergic therapy. We aim to showcase our experience with the diagnosis of pheochromocytoma in a known case of Parkinson's disease receiving levodopa.Methods We present a case of an elderly male who was diagnosed as pheochromocytoma while receiving dopaminergic therapy for Parkinson's disease.Results A 75 year-old man presented with vague abdominal symptoms. Computed tomography revealed a 3.5 x 3.2-cm right adrenal mass with a well-defined margin. As revealed by magnetic resonance imaging, the mass was hypointense on T1-weighted and hyperintense on T2-weighted images. Biochemical tests revealed elevated levels of urinary dopamine, which was considered to be caused by levodopa therapy. However, the concurrent elevation of urinary adrenaline, and metanephrine, vanillylmandelic acid levels suggested an underlying of pheochromocytoma. 123I-metaiodobenzylguanidine (123I-MIBG) scintigraphy performed under levodopa therapy, showed positive tracer uptake in the right adrenal gland. Histopathology of the adrenalectomy specimen confirmed the diagnosis of pheochromocytoma.Conclusion Our experience with the present case indicates that although the standard diagnostic biochemical tests for pheochromocytoma may be confounded by dopaminergic therapy, 123I-MIBG scintigraphy has diagnostic value for confirming pheochromocytoma even in patients receiving dopaminergic therapy.
