Diffuse cavitary lung lesions.

An 11-year-old girl presented with a 2-month history of progressively worsening cough, daily fevers, and weight loss. A chest radiograph revealed multiple cystic cavitary lung lesions. An extensive infectious work-up was negative. Chest CT verified multiple cavitary lung lesions bilaterally, and [F-18]2-fluoro-2-deoxy-D-glucose ((18)F-FDG) positron emission tomography with CT (PET/CT) showed increased uptake in the lung lesions as well as regional lymph nodes. Subsequent biopsy of an involved lymph node confirmed classical Hodgkin lymphoma, nodular sclerosis type. This case represents an unusual presentation for a child with Hodgkin lymphoma and demonstrates a role for (18)F-FDG PET/CT in evaluating a child with cavitary lung lesions.

Vascular compromise as a cause of sudden death in a pediatric patient with widely metastatic testicular germ cell tumor.

During hospitalization for evaluation of a large testicular tumor with extensive metastatic disease, this 14-year-old boy collapsed while showering and could not be resuscitated. At autopsy, there was no evidence of thromboembolic phenomenon, a known cause of sudden death in metastatic testicular tumors and other large abdominal tumors. However, marked compression of the inferior vena cava by a large pelvicoabdominal tumor mass and findings suggestive of systemic-portal shunting were consistent with the death due to the impaired venous return via the inferior vena cava.
