AbstractCystic hygroma of the parotid gland is an uncommon benign congenital neoplasm that presents as an asymptomatic soft fluctuant mass. Cervical ultrasonography, computerized tomography (CT) and magnetic resonance imaging (MRI) are used to assess the size and extent of the lesion and to assist in planning the surgical approach. Ultrasonography may demonstrate a multilocular cystic mass containing septa of variable thicknesses. Extension of the mass into deeper structures is more accurately assessed by CT or MRI. A CT scan may show thin-walled cystic masses filled with material of density close to that of water. The use of contrast medium can demonstrate the relationship of the lesion to the surrounding structures. Magnetic resonance imaging is superior to CT in defining the nature and extent of the lesion.

ABSTRACT Pleomorphic adenoma is a benign tumor of the salivary glands, most commonly affecting the parotid gland. Pleomorphic adenoma of the ear is rare. The use of imaging modalities, especially magnetic resonance imaging (MRI), is particularly useful in localizing and surgical planning of these tumors. We present a case of pleomorphic adenoma invading the mastoid cortical bone, with review of literature. How to cite this article Vamanshankar H, Parida PK.

Abstract Objectives The purpose of this study was to correlate lumbosacral spinal ultrasound (LUS) and magnetic resonance imaging (MRI) findings in patients with lumbosacral spinal dysraphisms to evaluate the value of LUS in diagnosis, intraoperative use, and during follow-up of those patients. Methods A total of 24 patients aged up to 6 years old were operated for lumbosacral spinal dysraphisms at the Neurosurgery Department of Zagazig University hospitals during the period from January 2017 to August 2018. All patients were investigated preoperatively, intraoperatively, and on follow-up by LUS to compare the data with preoperative and follow-up MRI of the spine. Results The median age was 11 months at the time of surgery. The most common anatomical description from the LUS study was thickened filum (18 cases). Using MRI findings as the standard reference, the sensitivity of LUS in detecting a thickened filum was 77.8% preoperatively and 62.5% postoperatively, with a specificity of 100%. The sensitivity and specificity of detecting conus level, solid masses, and cystic masses were 100%. Conclusions Lumbosacral spinal dysraphisms can be evaluated well by ultrasound imaging in age group up to 6 years old with 100% specificity (true negative) in comparison with MRI.

Left Parotid Gland

A 4-month-old infant presented with a painless swelling overlying the left angle of mandible. Ultrasound and magnetic resonance imaging (MRI) revealed a large lesion replacing the entire left parotid gland, with multiple enlarged vessels. Homogeneous enhancement of the lesion was seen on the postcontrast MRI scans. Based on the imaging features, a diagnosis of infantile hemangioendothelioma of the parotid gland was offered. This helped in avoiding any further invasive testing.

ABSTRACT A 24-year-old woman, G5P4, presented for a routine checkup at 28 weeks gestation. Ultrasound of the fetus showed a neck mass with no other anomalies and no polyhydramnios. Magnetic resonance imaging (MRI) of the fetus showed a cystic mass suggestive of a neck teratoma. She was continued with her pregnancy as planned and was scheduled for a cesarean section at 37 weeks gestation. Ex utero intrapartum treatment (EXIT) procedure was performed. There were no intraoperative or postoperative complications. How to cite this article Al-Baghdadi R, Kika N, Ahmed B, Porovic S. Ex utero Intrapartum Treatment Procedure for Fetal Neck Teratoma.
