Thyroid haemangiosarcoma in a seven-year-old female Shih Tzu

Canine thyroid tumours are uncommon and the majority of tumours are carcinomas or adenomas, with only very few mixed tumours or metastases from distant sites described to date. A primary thyroid haemangiosarcoma has never been reported in veterinary medicine. In this case report, we describe a dog with a history of a large, non-painful, mobile ventral neck mass in the right paralaryngeal region. CT and ultrasound-guided fine needle aspirates were used for clinical staging. The mass was surgically excised and histopathological examination indicated a haemangiosarcoma. Abdominal ultrasound revealed the presence of splenic nodules and splenectomy indicated the presence of haemangiosarcoma. Chemotherapy with doxorubicin was started, but the dog was euthanased after three rounds of therapy, 97 days after the mass was discovered.

A 12-y-old neutered male Portuguese Water dog was presented because of a 1-y history of persistent hyporexia, diarrhea, and recurrent pyelonephritis. Abdominal ultrasound revealed hepatic nodules and diffuse splenomegaly, and radiographs revealed a mediastinal mass. Fine-needle aspirates of the liver, spleen, and mediastinal mass were suspicious for lymphoma. Flow cytometry identified small T cells that co-expressed CD4 and CD8 at all sites, most suspicious for thymoma, but lymphoma could not be ruled out. PCR for antigen receptor rearrangements analysis identified polyclonal amplification of the T-cell receptor genes, more consistent with thymoma than lymphoma. Histopathology of the liver and thymic mass confirmed thymoma with hepatic metastasis.

ABSTRACT A 4 mo old intact male Labrador retriever was referred to the authors’ institution for a 3 wk history of weight loss and progressive abdominal distension. Thoracic radiographs revealed sternal lymphadenopathy and a diffuse unstructured interstitial and bronchial pulmonary pattern. An abdominal ultrasound revealed multifocal lymphadenopathy, hepatosplenomegaly, and biliary duct dilation. Fine-needle aspirates of the spleen and liver revealed Histoplasma capsulatum organisms. Antifungal therapy was initiated with itraconazole and terbinafine. Repeat ultrasound examinations revealed resolving hepatosplenomegaly and resolving cystic duct dilation. Ultrasonographic findings mirrored a decrease in urine H capsulatum antigen levels. Histoplasmosis should be considered as a differential for unexplained biliary duct dilation or obstruction in dogs. Dogs with disseminated histoplasmosis should be monitored for this potential complication.

Abstract: Diverticulitis of the vermiform appendix is a rare disease with clinical features often similar to conventional acute appendicitis. The importance of appendiceal diverticulosis is the fact that it can lead to an early and a higher incidence of perforation and therefore a higher mortality rate, in contrast to acute appendicitis alone. In this study we present the clinicopathology, diagnosis and therapy of the disease with a review of the literature. A 65-year-old woman presented to the emergency department with a 48-hour history of intermittent pain in the right iliac fossa. Abdominal ultrasound raised the possibility of acute appendicitis but because of the relative asymptomatic state of the patient, the lack of fever and rebound tenderness we started observation. After 2 days with episodic abdominal pain, the patient was taken to the operating theatre for laparoscopic exploration. Intraoperatively, multiple diverticula were noted on the appendix and appendectomy was performed. Histopathological examination revealed diverticulosis and inflammation of the appendiceal wall. Due to the possible complications, the difficult preoperative diagnosis and its frequent association with appendiceal neoplasm, appendiceal diverticulosis requires special attention. For asymptomatic cases, incidentally diagnosed intraoperatively or discovered by radiology prophylactic appendectomy is recommended. Orv Hetil. 2018; 159(19): 768–772.

Glucose Test

Case summary A 9-year-old male neutered Maine Coon cat presented with a 6-month history of polyphagia and one recent episode of tremors and weakness. Blood work revealed profound hypoglycemia and results of a paired insulin glucose test were consistent with an insulinoma. Abdominal ultrasound revealed a solitary pancreatic mass, and results of a fine-needle aspirate (FNA) gave further support for the location of the neuroendocrine tumor. After unsuccessful medical management of the hypoglycemia, the mass was surgically removed. Immunohistochemistry confirmed that it was an insulinoma. At the time of writing, the patient had been in clinical remission for 9 months. Relevance and novel information Feline insulinomas are rare and there is very little information on their behavior, clinical course and histologic characteristics. This is the first reported case of an insulinoma in a Maine Coon cat and the first to describe results of an ultrasound-guided FNA of the mass. In addition, the progression of disease, histopathology and immunohistochemistry results add to the currently minimal database for feline insulinomas.

Popliteal artery thrombosis may present as a complication of an osteochondroma located in the vicinity of the knee joint. This is a case report of a 26-year-old man with symptoms of the right lower extremity ischaemia without a previous history of vascular disease or trauma. Plain radiography, magnetic resonance angiography and Doppler ultrasonography documented the presence of an osteochondrous structure of the proximal tibial metaphysis, which displaced and compressed the popliteal artery, causing its occlusion due to intraluminal thrombosis..The patient was operated and histopathological examination confirmed the diagnosis of osteochondroma.

A 71-year-old man with known history of atrial fibrillation (treated with routine rivaroxaban therapy) was found to have incidental biochemical elevated calcium and parathyroid hormone (PTH) levels. His physical examination demonstrated the presence of a palpable right neck mass. Subsequent imaging studies revealed a large parathyroid mass as well as multiple bone lesions, raising the suspicion of parathyroid carcinoma. The anticoagulant therapy was stopped 5 days prior to his elective surgery. The night before his elective surgery, he presented to the emergency room with profound hypocalcemia. The surgery was postponed and rescheduled after calcium correction. Intraoperative findings and detailed histopathological examination revealed an infarcted 4.0 cm parathyroid adenoma with cystic change. His bony changes were related to brown tumors associated with long-standing hyperparathyroidism. Autoinfarction of a large parathyroid adenoma causing severe hypocalcemia is a rare phenomenon and may be considered in patients with large parathyroid adenomas after withdrawal of anticoagulants.

Abstract: Post-catheterization PSA occurs at the site of arterial puncture followed by incomplete hemostasis. We reported a 63-year-old male visited the emergency department of Prof Dr. R. D. Kandou Hospital with chief complaints of swelling and severe pain on the right arm, occured 6 days prior to the ER visit. His right arm looked darker and felt colder than the counterpart, felt numb, and was hard to move due to pain. Three months ago, the patient had a history of percutaneous transluminal coronary angiography through brachial artery access. Examination of the right upper extremity revealed hematoma at brachial artery puncture site, edema at 1/3 distal of the brachial region, cold acral areas, strong right brachial artery pulses, yet small radial ones. Vascular Doppler examination showed a superficial hematoma above the brachial artery and a PSA pouch of 1.23 x 1.67 cm with a small neck (<0.5 cm). Colour Doppler displayed a “yin and yang” flow at pouch, while pulsed-wave Doppler showed a “to and fro” wave through the neck. Patient was diagnosed as iatrogenic brachial artery pseudoaneurysm and managed with ultrasound-guided compression technique followed by continuous compression with elastic bandage. This technique was selected due to the PSA size less than 3 cm yet symptomatic, small neck size (<1 cm), and no size progression. Patient discharged after the PSA pouch and neck shrinked. On 6 months follow-up, neither neck nor pseudoaneurysm pouch were found.Keywords: pseudoaneurysm, ultrasound-guided compression Abstrak: PSA pasca kateterisasi terjadi pada arteri yang dipungsi tetapi tidak terjadi hemostasis sempurna. Kami melaporkan seorang laki-laki berusia 63 tahun datang di Instalasi Rawat Darurat Medik RSUP Prof. Dr. R. D. Kandou dengan keluhan utama bengkak dan nyeri hebat pada lengan kanan sejak 6 hari SMRS dan memberat pada satu hari terakhir. Tangan kanan tampak lebih gelap dibandingkan tangan kiri, teraba dingin, terasa kebas dan sulit digerakkan karena nyeri. Tiga bulan sebelumnya pasien dilakukan tindakan intervensi koroner perkutan. Pada pemeriksaan ekstremitas atas kanan tampak hematoma di daerah pungksi, edema setinggi 1/3 distal regio brachialis sampai ujung jari, akral teraba dingin, pulsasi arteri brakialis teraba kuat tetapi arteri radialis teraba kecil. Pemeriksaan Doppler vascular mendapatkan gambaran hematoma superfisial dari arteri brakialis dan tampak kantong PSA berukuran 1,23x1,67 cm dengan neck berukuran kecil (<0,5 cm) Pada colour Doppler didapatkan aliran pada kantong pseudoaneurisma seperti gambaran yin dan yang. Pada pulsed-wave Doppler di saluran PSA (neck) didapatkan gelombang “to and fro”. Berdasarkan anamnesis, pemeriksaan fisik dan penunjang pasien ini didiagnosis dengan PSA arteri brakialis iatrogenik (pasca kateterisasi). Penanganan dengan ultrasound-guided compression dan dilanjutkan dengan kompresi kontinu dengan bebat elastik. Pemilihan teknik kompresi ini berdasarkan pada ukuran kantong <3 cm namun bergejala, ukuran neck kecil <1cm serta tidak didapatkan pembesaran progresif. Pasien dipulangkan setelah kantong maupun neck PSA tampak mengecil, dan 6 bulan setelahnya tidak lagi terlihat neck maupun kantong PSA.Kata kunci: pseudoaneurisma, ultrasound-guided compression

Poor body condition (5/5), muffled heart sounds (5/5), weak femoral pulse (5/5), ascites (5/5), inspiratory or inspiratory-expiratory dyspnea (5/5), pulsus paradoxus (2/5) and jugular vein distension (2/5) were the prominent clinical findings, while mature neutrophilic leukocytosis (3/5), lymphopenia (3/5), eosinopenia (3/5), hypoproteinemia (5/5) and increased urea nitrogen (3/5) were the most prevalent clinicopathologic abnormalities. Apart from a space-occupying lesion onto the right atrial wall of one dog (case 4), radiographic and ultrasound examination showed a globe-shaped cardiac silhouette (5/5), pericardial effusion (5/5), ascites (5/5) and pleural effusion (4/5). A large amount of non-clotting hemorrhagic effusion was drained during pericardiocentesis, resulting in rapid clinical recovery. Physical, chemical and cytological evaluation of the pericardial fluid was non-contributory in the differentiation between neoplastic and non-neoplastic causes of these effusions. Case 3 died 25 days post-pericardiocentesis; right atrium hemangiosarcoma and pulmonary metastases were documented on post mortem histopathological examination. Another dog (case 5) died of unknown causes one month after pericardiocentensis. On the contrary, dogs 1, 2 and 4 were still clinically healthy for a followup period of 16, 2 and 8 months, respectively.

Abstract Background Endoscopic ultrasound-guided liver biopsy (EUS-LB) using a 19-gauge (19-G) EUS needle is becoming increasingly popular. We evaluated the efficacy and safety of a 22-G EUS fine needle biopsy (FNB) needle for performing EUS-LB. Methods Patients referred for evaluation of elevated liver enzymes and without obstructive disease requiring endoscopic retrograde cholangiopancreatography (ERCP) were included. Using a 22-G FNB needle, two passes were made from the left lobe and one from the right. The main outcome measure was adequacy of the specimen for histology interpretation, and the secondary outcome was the safety of EUS-guided liver biopsy with a 22-G FNB needle. Patients were followed for post-procedure complications for 30 days. Results 40 patients (median age 61 years; 26 women) underwent EUS-LB. Analyzing by needle passes, the median longest core fragment was 12 mm (1st quartile – 3rd quartile 10 mm – 16.25 mm, interquartile range [IQR] 6.25 mm) from the left lobe and 11 mm (10 mm – 15.75 mm, IQR 5.75 mm) from the right lobe. The median cumulative core length per patient was 55 mm (44.5 mm – 68 mm, IQR 23.5 mm). The median cumulative number of complete portal triads (CPTs) per patient was 42 (28.5 – 53, IQR 24.5). The specimen was considered adequate in all 40 patients (100 %). Self-limiting abdominal pain was reported in 6 patients (15 %). Conclusions EUS-LB using a 22-G FNB needle is a safe and viable alternative to the use of larger gauge needles, yielding adequate tissue for evaluation of parenchymal disease in 100 % of the patients.
