Intrapancreatic accessory spleen
ABSTRACT An asymptomatic 79-year-old woman, with incidental finding on abdominal ultrasound of a solid nodule in the tail of the pancreas. Magnetic resonance imaging showed a 12mm solid tumor. The suggested diagnosis was pancreatic neuroendocrine tumor. The pathological examination showed an intrapancreatic splenic tissue. This is a rare ectopic location of spleen tissue and it should be considered in the differential diagnosis of pancreatic solid tumors.
Differential diagnosis of dental fluorosis made by undergraduate dental students
ABSTRACTObjective To check knowledge of undergraduate dental students to make diagnosis of dental fluorosis with varying degrees of severity and choose its appropriate treatment.Methods Data were collected using a semi-structured questionnaire addressing knowledge of undergraduates based on ten images of mouths presenting enamel changes.Results Only three images were correctly diagnosed by most undergraduates; the major difficulty was in establishing dental fluorosis severity degree.Conclusion Despite much information about fluorosis conveyed during the Dentistry training, as defined in the course syllabus, a […]
Extensive cervical lymphadenitis mimicking bacterial adenitis as the first presentation of Kawasaki disease
Cervical adenitis >1.5cm in diameter is the less frequently observed criteria in patients with Kawasaki disease and it is usually found in association with other symptoms during the acute phase. Moreover, the finding of fever and lymphadenitis with intense local signs of inflammation and phlegmon is rarely seen as the initial manifestation of Kawasaki disease. We report the case of a 7-year-old boy who had cervical lymphadenitis with adjacent cellulitis and phlegmon mimicking bacterial adenitis as the first presentation of […]
Transcranial sonography in Parkinson’s disease
Transcranial sonography has become a useful tool in the differential diagnosis of parkinsonian syndromes. This is a non-invasive, low cost procedure. The main finding on transcranial sonography in patients with idiopathic Parkinson’s disease is an increased echogenicity of the mesencephalic substantia nigra region. This hyperechogenicity is present in more than 90% of cases, and reflects a dysfunction in the dopaminergic nigrostriatal pathway. This study discussed how the hyperechogenicity of the substantia nigra may facilitate the differential diagnosis of parkinsonian syndromes.
Meningoencephalitis associated with Mycoplasma pneumoniae
We report a case of a child with meningoencephalitis of atypical etiology. The patient developed the disease after an infection in the upper airways with unfavorable evolution. The clinical recovery was only possible after the administration of adequate antibiotic therapy for the etiological agent. This case report describes a child with meningoencephalitis of atypical etiology. The patient developed the disease after an infection in the superior airways with negative evolution. The clinical recovery was possible only after the introduction of […]
