O ameloblastoma é considerado o tumor odontogênico clinicamente mais comum, segundo Neville. Tem origem epitelial odontogênica, podendo surgir dos restos da lâmina dentária de órgão de esmalte em desenvolvimento, das células basais da mucosa oral e do revestimento epitelial de um cisto odontogênico. São tumores de crescimento lento, porém invasivos e não possuem predileção por gênero. O objetivo deste estudo é relatar um caso de ameloblastoma sólido em um paciente de 12 anos apresentado ao serviço de Cirurgia Oral e Maxilofacial no Hospital Federal dos Servidores do Estado com história de mudança de posição e mobilidade da porção anterior dos dentes mandibulares e aumento do volume de sínfise. A análise da radiografia panorâmica revelou uma grande lesão radiolúcida e unilocular, que se estende do dente 34 ao dente 45, sugerindo o diagnóstico de ameloblastoma unicístico. A tomografia computadorizada mostrou uma lesão expansiva com substancial perda óssea cortical. A biópsia foi realizada e o histopatológico revelou que se tratava de um ameloblastoma sólido com padrão plexiforme. O tratamento de escolha foi excisão e ostectomia periférica. O paciente teve um acompanhamento de cerca de 8 anos sem recorrência.Palavras-chaves: Tumor odontogênico, Ameloblastoma, Ameloblastoma sólido, Cirurgia, Tratamento conservador, Paciente pediátrico. ABSTRACTAmeloblastoma is considered the clinically most common odontogenic tumor, according to Neville. It has an odontogenic epithelial origin, and may arise from the remains of the dental enamel organ in development, the basal cells of the oral mucosa and the epithelial lining of an odontogenic cyst. They are slow-growing tumors, but they are invasive and have no predilection for gender. The aim of this study is to report a case of a solid ameloblastoma in a 12-year-old presented to the Oral and Maxillofacial department at HFSE (Hospital Federal dos Servidores do Estado) with a history of change in position and mobility of the anterior mandibular teeth and increased volume of symphysis. Panoramic radiograph analysis revealed a large radiolucent and unilocular lesion, extending from the element 34 to the element 45, suggesting the diagnosis of unicystic ameloblastoma. Computed tomographic scan showed an expansive lesion with substantial cortical bone loss. A biopsy was performed and the histopathological be revealed solid ameloblastoma of plexiform type. The treatment of choice was excision and peripheral ostectomy. This patient had a follow up about 8 years without recurrence.Key words: Odontogenic tumor, Ameloblastoma, Solid ameloblastoma, Conservative Treatment, Pediatric patient.

Abstract BACKGROUND: Our clinical understanding of os odontoideum (OO) remains incomplete. Congenital and traumatic causes have been proposed and advocated. Clinical presentations range from asymptomatic to axial pain to myelopathy or vertebral-basilar ischemia. A consensus for surgical management exists for those found to have an unstable atlantoaxial complex or symptomatic cranial-vertebral junction compression. OBJECTIVE: To evaluate the clinical presentation and surgical outcomes of patients with OO and an unstable atlantoaxial complex or symptomatic cranial-vertebral junction compression. METHODS: Patients with a diagnosis of OO who underwent surgical management were included. Patients were excluded on the basis of previous C2 fracture, Fielding diagnostic criteria, and inadequate follow-up. History of trauma and presenting symptoms were assessed. Clinical and neurological improvements were measured with the use of patient satisfaction scores and the Japanese Orthopaedic Association scores. Fusion status was documented with the use of radiographs and computed tomographic imaging. RESULTS: Of 279 patients, 112 reported a history of cranial-vertebral junction trauma, whereas 28 were diagnosed with congenital malformations. Clinically, 84.9% of patients presented with myelopathy, with pain presented in 42.6%. Atlantoaxial fixation was performed in 240 patients, occiput-to-C2 fixation in 35 patients, and extended occipito-cervical fixation in 4 patients. Mean follow-up was 40.3 months. Complications were reported in 2.4% of patients. Japanese Orthopaedic Association scores improved from a preoperative mean of 12.4 to 14.8. Two hundred thirty-five patients (77.7%) improved, with 30 patients experiencing no change in symptoms and 14 patients deteriorating. Fusion was achieved in 96.8% of patients. CONCLUSION: Our data reveal that surgical treatment for OO using the indications and techniques delineated is associated with high satisfaction rates, improved functional scores, and high fusion rates with low complication rates.

Bronchiectasis is characterized by permanent destruction of the airways that presents with productive cough, as well as bronchial wall thickening and luminal dilatation on computed tomographic (CT) scan of the chest; it is associated with high mortality. Accumulating data suggests higher rates of bronchiectasis among the HIV-positive population. This case series involves 14 patients with bronchiectasis and HIV followed at two major urban institutions from 1999 to 2018. Demographics, clinical presentation, microbiology, radiographic imaging, and outcomes were collected and compiled. Mean age was 42 years (range 12-77 years). 36% had a CD4 count greater than 500 cells/mm3, 28% had a CD4 count between 200 and 500 cells/mm3, and 36% had AIDS. 43% were treated for Pneumocystis jiroveci pneumonia (PJP) and 50% for Mycobacterium avium complex (MAC) infection. 21% had COPD, 7% had asthma, and 7% had a history of pulmonary aspergillosis. Two patients were followed up by pulmonary services after diagnosis of bronchiectasis on CT. The timeline of the follow-up in these cases was within months and after three years respectively. It is posited that the prevalence of bronchiectasis in HIV patients may be underestimated. Improving recognition and management of bronchiectasis could help diminish rehospitalization rates.

Abstract We report the case of a sarcomatoid carcinoma with a rhabdoid tumor component originating in the gallbladder, along with immunohistochemical and electron microscopic findings. A 61-year-old woman presented with a 5-month history of right upper quadrant pain. Ultrasonography and a computed tomographic scan indicated gallbladder cancer. She underwent a cholecystectomy and a common bile duct resection. A firm mass (4.5 cm in greatest dimension) was present in the neck portion of the gallbladder. The mass was firm, solid, yellowish gray, and granular with areas of necrosis. Microscopically, the tumor was a biphasic sarcomatoid carcinoma and consisted of diffusely arranged pleomorphic cells, focally showing rhabdoid features and neoplastic glands with focal mucin production. Heterologous components such as osteoid, chondroid, and rhabdomyoblastic elements were not identified. By immunohistochemical staining, we demonstrated that the rhabdoid cells coexpressed cytokeratin and vimentin. On electron microscopic examination, the rhabdoid tumor cells showed cytoplasmic whorls of intermediate filaments in the cytoplasm and eccentric nuclei. Two months postoperatively, the follow-up computed tomographic scan showed multiple intrahepatic metastases and omental seedings.

OBJECTIVE: This article presents a case of ossifying fibroma (OF), including its diagnosis, treatment, and 15-month clinical and radiographic follow-up as well as a review of the literature about this pathology.CASE REPORT: A routine panoramic radiograph of a 27-year-old, systemically healthy, white woman revealed a radiolucent lesion with well-defined sclerotic margins of approximately 3 × 2 cm in the mandible. The histopathological diagnosis revealed it was an OF. Lower Right Canine and Lower Right First Premolar teeth were endodontically treated for later surgical removal of the tumor. There was no history of trauma in the region.CONCLUSION: OF is a benign fibro-osseous tumor of the craniofacial bones commonly involving the jaws, especially the mandible. The diagnosis is based on a combination of clinical, radiographic and histologic criteria. Conservative treatment is an effective option that reduces morbidity and simplifies postoperative rehabilitation. We emphasize the importance of properly documenting individual cases and interpreting postoperative radiographic images along with the patients in order to avoid possible confusion between areas of bone repair and of potentially suspicious lesions in the future.

AbstractA 5-month-old, male French bulldog was presented with a history of urinary incontinence. Abdominal ultrasound showed changes compatible with a ureterocele and a bilobed right kidney. Excretory computed tomographic urography was consistent with right-sided duplex kidney, ureter duplex and ectopic ureterocele. To the authors’ knowledge, this is the first description of a duplex kidney with an ectopic ureterocele diagnosed with ultrasound and contrast enhanced computed tomography in a dog. After the imaging diagnosis, a neoureterocystostomy was performed. In the follow-up examination the dog presented with mild incontinence which was treated medically using phenylpropanolamine.

Introduction. Cementoblastoma is a rare and benign odontogenic mesenchymal tumor, often characterized by the formation of cementum-like tissue produced by neoplastic cementoblasts attached to or around the roots of a tooth.Case Report. 22-year-old male patient was referred to the Federal University of Paraná after occasional finding on a routine panoramic radiograph. Clinical examination suggested no alterations. Medical and family history presented no alterations as well. Computed tomographic (CT) showed the presence of a radiopaque area associated with the roots of the impacted third molar measuring 15 mm × 10 mm inside the left maxillary sinus. The treatment plan suggested was to surgically remove it under general anesthesia. An intraoral approach was conducted, using the Newmann incision from the superior left first molar to the retromolar area with anterior and posterior relaxant incisions. Using a Caldwell-Luc access next to the maxillary tuberosity region, the maxillary sinus was exposed and the calcified mass attached to the roots of the tooth was reached. Pathological mass removed was sent for histopathological investigation. Examination revealed dense, mineralized, cementum-like material and vascular soft tissue areas that consisted of cementoblasts. One-year follow-up shows no recurrence and absence of symptoms.

AbstractAn 8-year-old boy was brought to the emergency room with history of fall from a bicycle he was riding. On examination, he had a swelling in the left orbit with a small laceration under the medial aspect of the left eyebrow. The Glasgow coma scale was E2M5V2. An emergency computed tomographic (CT) scan showed infarct causing mass effect in the territory of the left middle cerebral artery. CT angiogram showed that a branch of the middle cerebral artery was occluded at the end of track traversed by the bicycle brake handle. The patient underwent decompressive craniectomy. Initial methylmethacrylate cranioplasty had to be removed due to infection. Later, the patient underwent titanium cranioplasty. At last follow-up, he was going to school. Hemiparesis persisted. Children are vulnerable to penetrating injury by the relatively sharp brake handle when they fall from an adult bicycle. Previous reports include fatal injury by similar mechanism. In this case, it caused injury to the middle cerebral artery without causing bleed. Bicycle manufacturers could be advised to make the vehicle safer for children by twisting the end of the brake handle.

Abstract OBJECTIVE To determine the accuracy of [18F]fluorodeoxyglucose (FDG) positron emission tomography (PET) in the diagnosis of vertebral metastases in patients with cancer using needle-biopsy results and patient follow-up data. METHODS A retrospective chart review of all patients who underwent a needle biopsy of a spinal lesion and underwent FDG-PET within 6 weeks of the biopsy was performed. Biopsy results and magnetic resonance imaging and computed tomographic appearance of the biopsied lesion, as well as long-term clinical follow-up data, were recorded for each patient. A total of 82 patients with solid tumors and hematological spine metastases were included in this study. RESULTS The mean standardized uptake values of lesions with active cancer were 7.1 and 2.1 in benign lesions (P < 0.02). In patients with metastatic solid tumors, the mean standardized uptake value was 7.3. Stratification of solid tumor lesions according to whether they had a sclerotic appearance on computed tomographic scans showed that FDG-PET was a significantly better predictor of cancer status in lytic or mixed lesions. In patients with a history of solid tumors, there was 100% concordance between the FDG-PET and needle-biopsy diagnoses in nonsclerotic lesions, when the standardized uptake value cutoff of 2 was used. CONCLUSION FDG-PET is an accurate screening test for vertebral metastases in cancer patients. It is especially accurate in patients with nonsclerotic vertebral lesions and a history of solid malignancy.
