SEQUENTIAL MAGNETIC RESONANCE IMAGING OF AN INTRACRANIAL HEMATOMA IN A DOG

An 8-year-old Yorkshire terrier developed acute onset coma and seizure after cranial trauma. Intracranial hemorrhage was suspected from the clinical signs and history. Low-field magnetic resonance (MR) imaging revealed a round mass within the right cerebral hemisphere, compressing the right lateral ventricle and displacing the longitudinal fissure to the left. The lesion was hypointense on T1-weighted images and hyperintense on T2-weighted images, consistent with an acute hemorrhage. MR imaging was performed every 24 h for 6 days from 1 h after the injury, and then on day 14 of hospitalization. With time, the signal intensity changed to hyperintense on Ti-weighted images. On T2-weighted images the center of the mass changed to hypointense, and then to hyperintense with a hypointense rim. These changes of signal intensity were related to hemoglobin oxidation.     

An Application of Continuation Method for Electrical Impedance Tomography in Brain Hematoma Case

It is a significative attempt in medical diagnosis that Electrical Impedance Tomography is used to hematoma monitoring. Since there is great difference in physiological parameters among different persons, among varieties of ill cases, and different tissues, it is important to loosen the limits of initial values of reconstruction algorithm. A new approach named Continuation method is proposed in Electrical Impedance Tomography. In addition, simulating calculation results are given to validate the approach effective.     

ULTRASONOGRAPHIC EVALUATION OF A TRAUMATIC SPLENIC HEMATOMA AND LITERATURE REVIEW

This report describes a presumed traumatic splenic hematoma in a six-year-old neutered male Greyhound presented for abdominal pain, vomiting, and anorexia. Multiple right-sided rib fractures and minimal pneumothorax were detected on radiographs. Using ultrasonography, an irregular, mixed anechoic and hypoechoic splenic mass was detected. Based on history and ultrasonographic findings, a traumatic splenic hematoma was diagnosed. In follow-up ultrasonographic evaluations there was progressive, and ultimately, complete resolution of this lesion. The animal was clinically normal at ten week follow-up and remains healthy. Clinical, radiographic, and ultrasonographic features of splenic hematomas are discussed, with emphasis on the changing ultrasonographic appearance over time. The different imaging modalities used in people to diagnose traumatic splenic hematoma are reviewed.

COMPUTED TOMOGRAPHIC EVALUATION OF HEAD TRAUMA IN A FOAL

This case report describes computed tomographic findings of a three-month-old, 180 kg female Arabian foal that had suffered head trauma. Computed tomography proved valuable in antemortem diagnosis of skull base fracture and extradural hematoma, which were confirmed by postmortem examination.     

Ventricular Arrhythmias in Dogs With Splenic Masses

The records of 73 dogs with splenic masses were evaluated retrospectively to determine whether ventricular arrhythmias, in the absence of clinically apparent underlying heart disease, were a common clinical finding. Associated clinical, laboratory, and pathologic findings were evaluated to search for clinical predictors of ventricular arrhythmias. Age, breed, weight, sex, coagulation abnormalities, electrolyte abnormalities, and hemoabdomen were unrelated to the development of arrhythmias (p > 0.05). Anemia was associated with the presence of arrhythmias (p = 0.005). Myocardial necrosis (10/18) and metastatic hemangiosarcoma (3/18) were common myocardial histopathologic findings. Proposed causes for arrhythmias in dogs with splenic masses include myocardial metastases, tissue hypoxia secondary to anemia or hypovolemia, and local or systemic catecholamine release.     

婴幼儿维生素K缺乏脑出血10例综合治疗疗效观察

目的探讨婴儿晚发性维生素K依赖因子缺乏致脑出血的诊断及外科治疗。方法本科自1994年10月~2003年10月对10例迟发性维生素K缺乏脑出血婴儿进行手术治疗。所有病例均在全麻下行骨窗开颅手术,在手术显微镜下将血肿全部清除,血肿清除后生理盐水反复冲洗完全止血,术腔置引流管,48h内拔管。结果全部病例经约1个月的治疗,均无复发,神经功能症状均有明显改善。无手术并发症。全部治愈出院。其中4例随访0.5~3年,3例生长发育良好,无任何神经系统异常表现。1例头小畸形伴智力发育落后。结论当幕上出血量>30mL,幕下出血量>15mL,或颅内压增高明显及有严重的神经功能障碍时宜采用手术治疗,可降低病死率和致残率。
