“…19,88 Diffusion-weighted imaging has been shown to be a useful additional diagnostic modality in identifying brain abscesses. 13,30,57,69,79 Restricted diffusion in brain abscesses has been assumed to be a consequence of inflammatory cells, necrotic debris, and the viscosity of the purulent material contained within the abscess; however, Mishra et al 69 showed that viable cell density is the main biological parameter responsible for restricted diffusion in brain abscesses.…”

✓ Brain abscesses occur infrequently but continue to be problematic for the pediatric neurosurgical community. The incidence of brain abscesses in children has not changed much, although individual reports may show an increase or decrease in the number of reported cases depending on the patient population studied. An increase could be attributed to earlier detection due to advancements in imaging modalities and/or to an increase in the number of children with immunodeficient states caused by AIDS, chemotherapy for malignant lesions, and immunosuppressive therapy for organ transplantation. A decrease in the incidence of brain abscesses could be attributed to practices such as antibiotic treatment for otitis media, sinusitis, and/or prophylactic antimicrobial treatment for congenital heart disease in children. The morbidity and mortality rates associated with brain abscesses have not changed dramatically in the antibiotic and imaging era, and their preferred management can vary among healthcare providers. These lesions have been successfully treated by neurosurgeons. The causes of brain abscesses are highly variable in children, which is also the case in adults, but the predisposing factors in the pediatric population differ in prevalence. Cyanotic congenital heart disease, hematogenous dissemination, contiguous infection, and penetrating traumatic injuries are the most common causes of brain abscesses in children. In this review, the authors discuss the causes and medical and surgical management of brain abscesses in children.

“…Both arachnoid cysts and epidermoids have signal characteristics similar to CSF and are indistinguishable on T1-and T2-weighted sequences, although epidermoid cysts do have elevated signal compared to surrounding CSF on FLAIR images. On DWI, arachnoid cysts have diffusion characteristics similar to CSF (markedly hyperintense to brain parenchyma on ADC and hypointense on DWI images), while epidermoids are markedly hypointense to CSF and isointense to brain parenchyma on ADC maps and are markedly hyperintense to CSF and brain parenchyma on DWI images due to T2 components and diffusion characteristics similar to that of normal brain parenchyma [223,295,296] (Fig. 2.31).…”

Abstract:Head and neck mass is considered to be a relatively common finding in adult and pediatric patients and can present a difficult diagnostic challenge. Differentiation of benign head and neck tumors from malignant lesions are important for treatment strategy as well as for predicting prognosis of malignant tumors. The aim of this work is to review the role of diffusion MRI scan in differentiation between benign and malignant head and neck masses This study was performed on 72 patients (30 men and 42 women aged from 13 years to 85 years, mean age of 51 years) with head and neck mass, in the period from September 2012 until May 2014. We found that DWI is a reliable noninvasive imaging tool to help in differentiation between malignant and benign head and neck lesions and also to identify the tumor-free soft tissue in patients with head and neck neoplasms. It could be performed with conventional MR systems in few minutes time, Further studies on larger number of patients is required to assess if such a technique should be implemented routinely with conventional MRI scan.
