Background. Teratomas are the most common tumors. They are usually localized in the sacrococcygeal area, while the pharyngeal localization is very rare. The number of cases of stomatopharyngeal teratomas detected prenatally via sonography is very small. Case Report. We present the case of a 24-year-old primipara at 18 weeks' gestation, that at the routine ultrasound scan, the fetus was found with an echogenic mass, filling the stomatopharyngeal cavity and protruding from the mouth. Other abnormalities were not found. Termination of pregnancy was achieved using misoprostol. A female stillborn fetus with a weight of 250 g and length of 25.5 cm was delivered. The postmortem and pathologic examination confirmed the diagnosis. Conclusion. Pharyngeal teratomas can be diagnosed with the use of ultrasounds in utero facilitating parents' counseling in early time.

This is a case of a 69-year-old male patient with long-standing iatrogenic hypoparathyroidism after total thyroidectomy. The clinical evaluation revealed mild neurological symptoms and excessive brain calcinosis. Intracranial calcification that affects structures other than the basal ganglia and the cerebellum is a rare manifestation of postoperative hypoparathyroidism. Detection of brain calcinosis in patients who had total thyroidectomy can motivate clinicians in further investigation of possible hypoparathyroidism with measurement of calcium and phosphorus serum levels.

Background: Trigeminal neuralgia (TN) is associated with multiple mechanisms involving peripheral and central nervous system pathologies. Among percutaneous treatments offered, radiofrequency thermocoagulation (RFT) is associated with longer duration of pain relief. Mostly due to anatomic variation, cannulation of the foramen ovale using the Hartel approach has a failure rate of 5.17%. Objectives: To report safety and efficacy of continuous RFT with an alternative to Hartel anterior approach under computed tomography (CT) guidance in patients with classic TN. Study Design: Retrospective institutional database review; bicentral study. Setting: Although this was a retrospective database research, institutional review board approval was obtained. Methods: Institutional database review identified 10 patients (men 8, women 2) who underwent CT-guided RFT of the Gasserian ganglion. Preoperational evaluation included physical examination and magnetic resonance imaging. Under anesthesiology control and local sterility measures, a radiofrequency needle was advanced, and its approach was evaluated with sequential CT scans. Motor and sensory electrostimulation tests evaluated correct electrode location. Pain prior, 1 week, 1, 3, and 6 months after were compared by means of a numeric visual scale (NVS) questionnaire. Results: Mean self-reported pain NVS score prior to RFT was 9.2 ± 0.919 units. One week after the RFT mean NVS score was 1.10 ± 1.287 units (pain reduction mean value of 8.1 units). At 3 and 6 months after thermocoagulation the mean NVS score was 2.80 ± 1.549 units and 2.90 ± 1.370 units, respectively. There were no postoperative complications. Three patients experienced facial numbness, which gradually resolved over a period of 1 month. Limitations: Retrospective nature; small number of patients; lack of a control group undergoing a different treatment of TN. Conclusions: Percutaneous CT-guided RFT of the Gasserian ganglion constitutes a safe and efficacious technique for the treatment of TN, with significant pain relief and minimal complication rates improving life quality in this group of patients.

Pneumatosis intestinalis and portomesenteric vein gas are rare and potentially severe radiological findings that occur both in pediatric and adult populations. They actually are radiographic signs of underlying intra-abdominal pathology, abnormality or diagnostic medical interference. If combined with other radiological or clinical signs of intestinal ischemia or sepsis, the prognosis is dismal and urgent laparotomy is mandatory. We report two cases of surgical treatment with ominous outcome in an effort to characterize this finding correctly as an absolute surgical indication or as an additional diagnostic criterion that simply marks a further breakdown of the systems in patients with a long list of severe medical conditions.
