Deep Brain Stimulation (DBS) is an effective surgical approach for treatment of Parkinson's disease (PD), dystonia and essential tremor (ET). Traditionally, DBS is performed using frame-based stereotactic technique. Recently, image guided surgery (IGS) using neuronavigation has gained popularity in neurosurgical procedures. We aim to investigate whether DBS using neuronavigation is capable of improving patient's outcome and minimize its complications. ⋯ IGS using neuronavigation allowed more accurate deep nucleus targeting, minimized intra- and post-operative complications and improved clinical outcome in DBS candidate patients. Our study revealed that increased white matter connections with remote parts of the brain would suggest that isolated deep nucleus stimulation could not explain symptom recovery and that patients' specific white matter stimulation by tractography coupled with IGS should be in priority.

The study evaluated the significance of 18F fluorodeoxyglucose (18F-FDG) uptake of bone marrow (BM) for predicting progression-free survival (PFS) in lymphoma patients without BM involvement. ⋯ In lymphoma patients without BM involvement, 18F-FDG uptake of BM was significantly associated with worse PFS. Patients with high 18F-FDG uptake of BM showed similar prognosis to those with BM involvement.

The Hellenic Journal of Nuclear Medicine is about to celebrate its 20th anniversary end of 2017. On board of the editorial team since 2003, this journal has influenced me like a good friend over the many past years. From time to time, the journal has published interesting and valuable historical notes. ⋯ Laios, M. Zozoglou. 2017; 20(1): Ahead of print. And hopefully many more to follow!

Adult liver Langerhans cell histiocytosis (LCH) is an extremely rare desease. This paper reports a 40 years old male patient who was diagnosed as liver LCH though ultrasound-guided liver biopsy. The initial Fluorrine-18- fluorodeoxyglucose positron emission tomography/ computed tomography (18F-FDG PET/CT) showed multiple nodular low-density lesions in liver without obvious elevated 18F-FDG uptake. Four years later, the follow-up 18F-FDG PET/CT showed the liver multiple lesions with slightly elevated 18F-FDG uptake. ⋯ We describe this case, to highlight the importance of 18F-FDG PET/CT in differential diagnosis for the primary disease and the multiple liver nodules.

Differentiation of vertebral metastases from Schmorl's nodes, especially with fluorine-18-fluorodeoxyglucose (18F-FDG) uptake, is very important for the appropriate management of these patients in case they have malignancy. We aimed to evaluate the value of 18F-FDG positron emission tomography/computed tomography (PET/CT) in differentiating vertebral metastases from Schmorl's nodes with 18F-FDG uptake. ⋯ Although the SUVmax in the Schmorl's nodes and vertebral metastases was similar, the 18F-FDG distribution characteristic in PET/CT can help differentiating the vertebral metastases from Schmorl's.
