Follicular lymphoid hyperplasia simulating intussusception in a 6-year-old boy: clinical, radiological and histopathological findings.

We report the case of a 6-year-old boy who initially presented with recurrent abdominal pain. Diagnostic imaging, including ultrasound and CT, showed findings typical of an ileocecal intussusception with abdominal lymphadenopathy. Sonographically, the morphological appearance of the intussusception did not change during a 4-week follow-up period. Surgery was performed on the tentative diagnosis of a tumour versus lymphoma. Upon laparatomy, intussusception was ruled out and a large, broad-based tumour of the caecum was palpable. The histopathology after ileocecal resection revealed follicular lymphoid hyperplasia. Where there is radiological suspicion of an intussusception in children with no or insignificant symptoms, follicular lymphoid hyperplasia should be included in the differential diagnosis.

Childhood multifocal skeletal non-Hodgkin lymphoma is a differential diagnosis of battered child syndrome.

Skeletal lesions observed in battered children include fractures, subperiostal new bone formation, irregular metaphyses, and cone-shaped epiphyses. A 4-year-old girl presented with bone pain. Radiographs revealed multiple fractures and epiphyseal and metaphyseal lesions highly significant for battered child syndrome. Six weeks later the authors diagnosed primary multifocal skeletal non-Hodgkin lymphoma. This case report illustrates that multifocal skeletal non-Hodgkin lymphoma is a differential diagnosis of battered child syndrome.
