Clinical Presentation and Cranial MRI Findings of Listeria monocytogenes Encephalitis

Objective: Takayasu arteritis is a rare granulomatous chronic vasculitis that affects the aorta and its main branches. Neurologic manifestations can accompany the disease; however, there is no study on neuroimaging in children with Takayasu arteritis. Therefore, we aimed to evaluate cranial magnetic resonance imaging (MRI) in pediatric Takayasu arteritis patients. Materials and Methods: Demographic, clinical, and laboratory data were obtained retrospectively. Results: The study included 15 pediatric Takayasu arteritis patients. All patients presented with constitutional symptoms. Additionally, 6 patients suffered from headache, 2 had syncope, 1 had loss of consciousness, and 1 had convulsion. All patients underwent cranial and diffusion MRI a median 12 months after diagnosis. Cranial MRI findings were normal in 12 patients, whereas 3 patients had abnormal findings, as follows: stenosis in the M1 and M2 segments of the left middle cerebral artery (n = 1); diffuse thinning of the right internal carotid, middle cerebral, and right vertebral and basilar artery (n = 1); as a sequela, areas of focal gliosis in both the lateral ventricular and posterior periventricular regions (n = 1). Among these 3 patients, 1 had no neurologic complaints. Conclusion: Abnormal MRI findings can be observed in pediatric Takayasu arteritis patients, even those that are asymptomatic; therefore, clinicians should carefully evaluate neurologic involvement in all pediatric Takayasu arteritis patients.

Vertebral Involvement

Incidence rate of lymphocytic leukaemia is unknown in canine patients; neurological manifestations and imaging findings are rarely reported. In human medicine, acute lymphocytic leukaemia is known to have a high rate of meningeal metastasis prompting the use of intrathecal chemotherapy for newly diagnosed cases regardless of neurological signs. This report documents the clinical presentation and diagnostic findings in a dog presenting with paraparesis and pain, ultimately diagnosed with aleukaemic lymphocytic leukaemia. MRI findings with diffuse vertebral involvement secondary to lymphocytic leukaemia have not been documented in the veterinary literature. This report adds to the clinical presentations of leukaemia in canines and highlights a neurological sequela of the disease. Further investigation into neurological involvement of leukaemia is needed in veterinary medicine and necropsy, with meningeal histopathology, is recommended for all cases of acute lymphocytic leukaemia in canines to assess the metastatic rate and direct further research.

Facial Nerve Schwannoma

Facial nerve schwannoma is a rare primary neurogenic tumour that may originate anywhere along the VIIth nerve course. The clinical presentation is highly dependent on the location of the lesion along the nerve course and this makes the pre-operative diagnosis difficult without radiologic examination. The most common presentation is facial palsy and even though tumours are responsible for only 5% of facial palsies, if a patient does not recover within six months a complete work-up for neoplasm is recommended. On the basis of clinical presentation and imaging characteristics radiologists should try to make a preoperative diagnosis, to help in the patient's management and possibly to plan the surgical approach. We describe the case of a successful preoperative diagnosis of facial nerve schwannoma. The aim is to describe the main CT and MRI findings which may help the radiologist to establish a correct differential diagnosis.

Objective: The aim of this study is to compare magnetic resonance imaging (MRI) findings with severity of hypoxic-ischemic encephalopathy (HIE) in term neonates. Methods: Sixty-three newborns with HIE in whom cranial MRIs were performed within the first 3 weeks of life between 2016 and 2020 were included in the study. Severity of HIE was graded using Sarnat & Sarnat staging. In statistical analysis, Stage 1 was considered as mild, Stage 2 or 3 as severe HIE. The signal intensities of perirolandic cortex, posterior limb of internal capsule (PLIC), globus pallidus, and cerebrospinal tract on T1- weighted imaging (T1WI), and of perirolandic cortex, PLIC, ventrolateral thalamus, lateral edge of putamen and tegmentum on T2WI, and brain diffusion weighted imaging (DWI) findings were evaluated with consensus by two radiologists blinded to clinical findings. Gestational age, birth weight and MRI signal intensities were compared with HIE groups using t test, and Fisher-Exact test. Results: There were 31 and 32 infants with mild and severe HIE, respectively. Gestational age and birth weight were not different between mild and severe HIE groups. The number of cases with abnormal signals in PLIC and globus pallidus on T1WI, and PLIC on T2WI were significantly higher in severe HIE (p=0.022, p=0.008, and p=0.032, respectively). The presence of signal abnormality in other regions and DWI were not significantly different between HIE groups. Conclusion: Cranial MRI may play a remarkable role in determining pattern and severity of HIE. Signal abnormality in PLIC and globus pallidus may suggest severe HIE in term neonates.
