RESUMEN
Teaching Point: The imaging findings of focal cortical dysplasia type 1 are less well-known than focal cortical dysplasia type 2 and consist of increased white matter signal intensity and blurring of the gray-white matter in a large region of the brain, with associated segmental or lobar brain atrophy.
RESUMEN
Teaching point: HHV6 encephalitis is a specific complication to be considered in a patient with neurological symptoms after hematopoietic stem cell transplantation and typically shows symmetrical involvement of the limbic system.
RESUMEN
Teaching Point: Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is an underrecognized and misdiagnosed cause of multiple lung nodules in combination with mosaic attenuation.
RESUMEN
With the widespread use of computed tomography (CT), subsolid nodules are more frequently encountered in daily practice. We present the case of a 74-year-old man with a large persistent well-defined subsolid nodule on CT. Although the lesion had a predominant ground-glass appearance on CT, 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) showed moderate FDG uptake. Lobectomy was performed and histopathologic examination showed an extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue. Teaching Point: When large persistent subsolid nodule with a predominant ground-glass aspect shows moderate uptake on 18F-FDG-PET, other possible diagnoses than adenocarcinoma should be kept in mind, including primary pulmonary lymphoma.
RESUMEN
Teaching point: Meticulous anamnesis and a high index of suspicion is needed for the diagnosis of Lyme arthritis.
RESUMEN
Teaching Point: Always look for an underlying (malignant) lead point as cause of a large bowel intussusception in adults.
