The case presented shows the clinical signs, diagnosis and surgical management of idiopathic bile duct cysts in a bearded dragon (Pogona vitticeps). A 12-year-old female bearded dragon presented with constipation resulting from the consumption of sand. A soft mass about 4 cm wide could be palpated in the mid-coelom after the substrate passed. The animal started eating, but soon started showing signs of kyphosis. Ultrasound, radiography and computed tomography examinations revealed that the mass was a cyst 4 cm in diameter. Diagnostic laparotomy was performed and the large cyst and affected liver tissue were removed with a partial hepatectomy. Cytology of the cyst was unremarkable, but histopathological examination showed the lesions to be bile duct cysts. No sign of malignancy or inflammation could be seen.

AbstractA 6.5-year-old female bearded dragon (Pogona vitticeps) was presented with a swollen right pelvic limb. A tissue core biopsy from the swollen area was performed and a presumptive histopathological diagnosis of adenocarcinoma was made. This diagnosis was confirmed after limb amputation. Two months after amputation a sudden deterioration in the overall health of the patient occurred. Ultrasound examination of the coelomic cavity revealed hypoechoic lesions in the liver. The patient was euthanized and submitted for necropsy which revealed a severely enlarged liver with multiple coalescing yellowish nodules. Cholangiocarcinoma of the liver with metastases to the spleen, left mesovarium and right pelvic limb was diagnosed after histopathological examination.

Nannizziopsis guarroi infection in lizards presents therapeutic challenges as reports of poor clinical outcomes, including antifungal toxicity, incomplete clearance of infection and recrudescence of infection are common. The case presented here describes the successful treatment of a N. guarroi infection using systemic terbinafine and environmental disinfection in a captive-bred central bearded dragon (Pogona vitticeps). The lizard presented with darkly colored cutaneous lesions and mycologic culture samples were identified as N. guarroi using Matrix-Assisted Laser Desorption/Ionization – Time Of Flight (MALDI-TOF). Based upon the lack of clinical resolution of cutaneous lesions, weight loss, and reduced appetite, initial treatment with voriconazole was discontinued. Terbinafine was prescribed and weekly environmental disinfection with sodium hypochlorite was initiated until cutaneous clearance of the fungus was confirmed by negative culture, histopathology, and N. guarroi qPCR from cutaneous swab. Terbinafine treatment was discontinued after 80 days. There were no clinical signs of toxicity associated with the prolonged treatment and the lizard has not developed any cutaneous lesions or illness in more than two years of clinical follow up. While the most ideal treatment of N. guarroi is still being investigated, this case demonstrates a promising and safe treatment option for an increasingly common and devastating disease.

ABSTRACT Pneumocephalus is defined as the presence of air in any of the intracranial compartments. Its most frequent causes are trauma and cranial surgery. Clinical signs occur as a result of increased intracranial pressure and vary with the location and extent of the lesion. A case involving a seven-month-old female Saint Bernard, who suffered cranial trauma caused by a bite to the face at ten days of age and had presented with seizures and localized pain four months previously is reported. A computed tomography scan of the skull revealed a nasocephalic mass with low contrast enhancement, bone lysis, and hypodensity (-940 Hounsfield units) of the lateral and third ventricles, indicating intraventricular pneumocephalus. During surgery, a fragment of the mass was collected for histopathological examination, which demonstrated the presence of multifocal areas of necrosis. The computed tomography (CT) is a reliable method for the characterization of intracranial lesions and diagnosis of pneumocephalus, whose occurrence must be considered in pathological processes in which there is increased intracranial pressure and in patients undergoing certain surgical procedures and anesthetic specific, and CT is indicated as a monitoring tool for these patients.

SummaryA nine-year-old spayed female Cocker Spaniel was investigated for an eight week history of licking and rubbing at the tail base, dullness, and signs of pain on manipulation of the tail. Left-sided intraforaminal compression of the first caudal nerve root due to intervertebral disc disease was diagnosed by radiographic, computed tomography, and magnetic resonance imaging examinations. The dog was non-responsive to conservative medical therapy. A decompressive left-sided first-second caudal (Cd1-Cd2) foraminotomy was performed.Postoperative computed tomography confirmed surgical decompression of the involved nerve root. At the one month follow-up examination there was marked improvement in clinical signs. At two months, clinical signs were completely resolved and there was not any evidence of recurrence twelve months after surgery.Intervertebral disc disease should be considered as a differential diagnosis in dogs with discomfort at the tail base or signs of pain on manipulation of the tail. Surgical decompression may be indicated for management of these cases.This is the first report of diagnosis and surgical management of caudal intervertebral disc disease by foraminotomy in the dog. Surgical decompression by foraminotomy may therefore be a treatment option for this condition.

A 2 yr old dog presented for dysphagia and coughing secondary to a 4 cm × 4 cm turgid subepiglottic mass. Cervical radiographs, an esophagram, and computed tomography confirmed the presence of a cystic mass that was not intimately associated with any surrounding structures. An incisional biopsy confirmed the cystic nature of the mass and helped to rule out a malignancy. A marginal surgical excision was performed via a ventral approach. Histopathology of the mass was consistent with a thyroglossal duct cyst. This is the first report of a thyroglossal duct cyst in this location in a dog. There was no recurrence of clinical signs 14 mo after surgery.

Non-alcoholic fatty liver induces many complications to the liver tissue and also serum related parameters. Medicinal plants are the safe therapeutic strategy for the treatment of diseases. In this regards, the present study was conducted to evaluate the effect of Tribulus terrestris L. (Zygophyllales: Zygophyllaceae) extract on non-alcoholic fatty liver in rats. In this experimental study, thirty male Wistar rats were divided into five groups (n = 6). Animals in experimental groups were received high fructose diet (70%) (HDF) daily alone or in combined with daily intraperitoneal injection of 500, 700 and 1,000 mg/kg extract of T. terrestris. Control group of rats was feed with standard chow. The serum levels of biomarkers of liver and serum lipid profiles were assessed, also histopathological examination of liver tissue done. Data were analyzed using One-way ANOVA method followed by Tukey’s post-hoc multiple comparison test and P < 0.05 was considered statistically significant. There were significant improvements for biomarkers of liver tissue (P < 0.05) and serum lipid profiles (P < 0.01) in the HFD-fed rats that were treated with T. terrestris extract compare to HFD-fed group. In addition, accumulation of lipids in hepatocytes was significantly reduced in the HFD-fed + extract administrated groups in comparison to HFD-fed rats (P < 0.01). T. terrestris extract has protective effects against non-alcoholic fatty liver by changing biomarkers of liver tissue, serum lipid profiles and histopathological anomalies of liver tissue, to normal range.

Oesophageal disorders are relatively uncommon in large animals. Oesophageal obstruction is the most frequently encountered clinical presentation in bovine and it may be intraluminal or extra luminal (Haven, 1990). Intraluminal obstruction or “choke” is the most common abnormality that usually occurs when foreign objects, large feedstuff, medicated boluses, trichobezoars, or oesophageal granuloma lodge in the lumen of the oesophagus. Oesophageal obstructions in bovine commonly occur at the pharynx, the cranial aspect of the cervical oesophagus, the thoracic inlet, or the base of the heart (Choudhary et al., 2010). Diagnosis of such problem depends on the history of eating particular foodstuff and clinical signs as bloat, tenesmus, retching, and salivation

AbstractScopolamine is an alkaloid which acts as competitive antagonists to acetylcholine at central and peripheral muscarinic receptors. We report the case of a 41-year-old male convict with a 27-year history of cannabis abuse who suddenly died in the bed of his cell after having smoked buscopan® tablets. Since both abuse of substances and recent physical assaults had been reported, we opted for a comprehensive approach (post-mortem computed tomography CT (PMCT), full forensic autopsy, and toxicology testing) to determine which was the cause of the death. Virtopsy found significant cerebral edema and lungs edema that were confirmed at the autopsy and at the histopathological examination. Scopolamine was detected in peripheral blood at the toxic concentration of 14 ng/mL in blood and at 263 ng/mL in urine, and scopolamine butyl bromide at 17 ng/mL in blood and 90 ng/mL in urine. Quetiapine, mirtazapine, lorazepam, diazepam, and metabolites and valproate were also detected (at therapeutic concentrations). Inmates, especially when they have a history of drug abuse, are at risk to use any substance they can find for recreational purposes. In prisons, active surveillance on the management and assumption of prescribed drugs could avoid fatal acute intoxication.

Cardiac calcified amorphous tumors are rare non-neoplastic intracavitary masses with unknown cause. A 60-year-old man presented with sustained ventricular tachycardia. Transthoracic echocardiography and contrast-enhanced angio-computed tomography demonstrated an expanding 73 × 40 mm sized calcified mass in the left ventricle. He underwent successful total removal of the mass and cryo-ablation at the normal myocardial border. Histopathological examination confirmed a diagnosis of cardiac calcified amorphous tumors. The postoperative course was uneventful, without ventricular tachycardia recurrence. To our knowledge, this is the first reported case of confirmed cardiac calcified amorphous tumors causing ventricular tachycardia and treated by surgical resection combined with cryo-ablation.
