We present a case of expansion in the oral cavity, referred from routine antenatal ultrasound screening to fetal MRI in 24^th gestational week for extension of diagnostic information concerning predominantly the character of tissue and relationship to adjacent structures. The aim of the presentation, which includes two fetal MRI and one MR performed immediately postnatal, is to specify which details could be obtain by evaluating the fetal MRI in such type of diagnoses and what is their practical application for influencing the outcome of the baby. Orofaryngeal teratomas are exceedingly rare and despite their usual benign histopathology they are potentially lethal due to airway obstruction. Complete surgical resection is the guiding principle of usually urgent postnatal management. The role of imaging method and MRI, with its tissue contrast, is the best method of the choice , is to establish the level of the airway compression, to specify the extent of the lesion for facilitating the postnatal planning , including the approach for resection . We emphasized some question the radiologist could be asked by involved surgeon, especially concerning the tongue involvement, as this factor definitely influenced the quality of life. Read More

The purpose of the pictorial review is to aid in understanding and identifying the spectrum of possible congenital oral lesions and make the radiologist familiar, as early detection of these is required to avoid potential perinatal and postnatal complications.

We performed a retrospective review of radiology reports from our pediatric hospital system, inclusive of our fetal imaging center, focusing on congenital oral lesions with prenatal or postnatal diagnoses. Utilizing multiple keywords through our radiology report data mining software, we reviewed cases over the last 15 years and grouped lesions based on the most likely diagnosis. Available prenatal and postnatal imaging, clinical management, and pathology was reviewed.

Our review of cases yielded both common congenital oral lesions, such as hemangiomas, as well as more extensive malformations and tumors of the face extending to the oral cavity. Lesions such as epulis, oral duplication cysts, and lingual ectopic thyroid were rarer in our review, but have imaging characteristics important to recognize by the radiologist. We selected representative images from the spectrum of congenital oral and outlined radiology and clinical teaching points. Read More

Peritonsillar abscess (PTA), as a consequence of acute tonsillitis is a very commonly encountered deep infection of the head and neck. Diagnosis of PTA and differentiation from uncomplicated cellulitis based on clinical findings has been shown to be very unreliable. Therefore, imaging diagnosis is a key step in management given the possible need for drainage, in addition to antibiotic therapy. Due to the widespread availability of real-time US, high resolution imaging of the tonsillar and peritonsillar tissue and confident diagnosis of PTA via an intraoral approach is feasible, with literature reporting sensitivities of 90-100%. This offers a valuable diagnostic alternative to the high radiation dose and expense of contrast enhanced CT in the pediatric population. The aim of this exhibit is to review sonographic technique, as well as the normal and pathologic appearance of the palatine tonsils via both transoral and transcutaneous approaches illustrated by a case series obtained at our institution.
