Latar belakang: tumor neuroendokrin (NETs) adalah neoplasma yang dapat mensekresi hormon dengan sindrom klinis yang bervariasi. Meskipun insidennya relatif rendah, NETs merupakan tantangan klinis karena presentasi klinis yang bervariasi dan tidak ada modalitas pencitraan awal yang dapat efektif. Kasus: didapatkan 5 kasus tumor neuroendokrin selama kurun waktu 2 tahun (2008-2010). Hampir sebagian besar pasien yaitu 80% mengeluh nyeri abdomen dan 1 orang pasien (20%) dengan keluhan sulit defekasi. Dari pemeriksaan pencitraan awal, ditunjukkan bahwa terdapat 2 subjek dengan asal tumor dari pankreas, 1 dari paraaorta kiri, 1 dari supra-renalis, dan 1 dari presakral. Pemeriksaan jaringan tumor melalui FNAB (fine needle aspiration biopsy) mengonfirmasi adanya Malignant Neuroendocrine Tumor pada semua pasien. Pada pemeriksaan penanda jaringan intraseluler semua menunjukkan peningkatan NSE yaitu berkisar dari 30,9-218,40 ng/ml. Dari penilaian resektabilitas tumor didapatkan 1 orang resektabel, 3 orang non-resektabel, dan 1 orang lagi menolak tindakan. Pada sebuah kasus dilakukan reseksi luas, yaitu tumor neuroendokrin pre-sakral yang sudah infiltrasi ke os sakrum (S3-4). Selama follow up paska operasi pasien ini didapatkan metastasis pada hepar dan meninggal 2 tahun kemudian. Simpulan: tumor neuroendokrin adalah bentuk neoplasma yang jarang dan muncul dengan berbagai variasi klinis. Penegakan diagnosis jaringan dapat dilakukan dengan FNAB guiding USG (ultrasonografi) atau CT dan pemeriksaan penanda jaringan NSE. Penentuan resektabilitas tumor dapat dilakukan dengan pemeriksaan CT, MSCT (multislice computed tomography) atau MRI (magnetic resonance imaging. Kesulitan dalam hal tindakan dan mortalitas yang tinggi disebabkan karena hampir sebagian besar pasien datang dalam keadaan tumor yang sudah lanjut.

Abstract Five canine patients were directed to low-field magnetic resonance imaging due to different neurological defects. In each case there were heterogeneous extraaxial masses covering left or right dorsal parietal and occipital lobes that were isointense to the brain on T1-weighted Spin Echo images, isointense to hypointense to the brain on T2-weighted Fast Spin Echo sequences and hypointense to the brain on Flair sequence. After MRI study fine needle aspiration biopsy of the tumors was performed. On the basis of the cytological examination fibrosarcomas with of moderate malignancy were diagnosed.

The role of routine preoperative magnetic resonance imaging (MRI) in newly diagnosed breast cancer patients planned for breast conserving surgery is presently being debated. In our medical center we practice selective use of preoperative MRI; we sought to examine the yield of MRI in this highly selected group of patients. A retrospective study of all newly diagnosed breast cancer patients presenting between January 2007 and July 2010 to the Tel Aviv Sourasky Medical Center (Tel Aviv, Israel) was completed. Patients planned for breast conserving surgery who underwent preoperative MRI were included in this study. Patients and tumor characteristics, indication for MRI, findings on MRI, consequent workup, and impact on surgical treatment were recorded. Association between preoperative characteristics and yield of MRI was examined. During the study period, 105 patients that were candidates for breast conserving surgery underwent pre-operative evaluation with MRI. Use of breast MRI increased over time. Rates of mastectomy were stable throughout the study years. Dense mammogram was the most frequent (51, 68%) indication for MRI. Additional suspicious findings were found in 41 (39%) patients, prompting further workup including 36 biopsies in 25 patients, of which 22 (61%) were with cancer. These additional findings prompted a change in the surgical plan in a third of the patients. In most patients (92; 88%) clear margins were achieved. Limiting the use of MRI in the preoperative workup of breast cancer patients to a selected group of patients can increase the yield of MRI.
