This study describes a case of a six-year-old female crossbreed dog that had a three months history of progressive right thoracic limb lameness. Palpation revealed muscle atrophy of the scapular and humeral area and painfulness in this region. Magnetic resonance imaging was performed in T1- and T2-weighted and STIR (short inversion recovery) sequences in sagittal and transverse planes. The masses around the scapula and humerus were heterogeneously hyper-intense in STIR and measured about 9 cm. The tumour was heterogeneously iso-intense relatively to the surrounding tissues in T-2 weighted Gradient Echo and Spin Echo sequences. After MRI fine needle aspiration of a central part of the tumour was performed. The biopsy revealed multiple round cells with very little cytoplasm and fusiform cells in which the cytoplasm created protrusions. Cells were arranged in rows or formed a homogeneous cell mass. A malignant peripheral nerve sheath tumour was diagnosed cytologically.

Summary Objectives: This case report describes for the first time a bone haemophilic pseudotumour in a dog. Case description: A seven-month-old German Shepherd male dog was presented with the complaint of a forelimb weight-bearing lameness with major swelling that expanded dramatically after fine needle aspiration. Radiographs showed a large, well-defined ulnar diaphyseal cystic-like osteolytic lesion. Based on prolonged activated partial thromboplastin time (aPTT) and low factor VIII activity, haemophilia A was diagnosed. Bone scintigraphy, computed tomography, magnetic resonance imaging, and histological findings definitely ruled out malignant neoplasia or inflammation and strongly supported a bone haemophilic pseudotumour over an aneurysmal bone cyst. Segmental ulnar resection and replacement by a polymethylmethacrylate spacer combined with perioperative bleeding management resulted in a successful outcome. Discussion: This case provided evidence that a bone haemophilic pseudotumour may be the sole presenting clinical sign of haemophilia A in dogs. Early diagnosis, based on history and magnetic resonance imaging findings, is imperative for prompt treatment leading to successful outcome. It is challenging as fine needle aspiration or biopsy is contraindicated. As described in humans, surgical excision of the lesion combined with management of severe postoperative bleeding was associated with successful outcome in the present case. Clinical significance: A bone haemophilic pseudotumour should be considered in the differential diagnosis of expanding mass associated with osteolysis, especially in young male dogs. Perioperative monitoring of the bleeding disorder and subsequent FVIII replacement therapy was of paramount importance in the present case.

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.
