Background: Bronchopulmonary foregut malformations are defined as aberrant communications between an isolated segment of respiratory tissue and the esophagus or stomach. Based on the anatomic relationship of the fistulous connection, these rare malformations are classified into four groups (I–IV). Diagnosis typically involves a combination of cross-sectional imaging (CT or MRI) and an upper gastrointestinal series (UGI). Case: A 1-month-old infant with a history of lipomyelomeningocele was transferred from an outside hospital for neurosurgical evaluation. An incidental right lower lobe (RLL) pulmonary mass was identified on spinal MRI. Further evaluation with contrast-enhanced CT revealed a RLL lesion with a systemic arterial supply from the celiac artery. Internal cystic and branching lucencies were also present, raising concern for a hybrid lesion. The patient was discharged, and readmitted four months later for neurosurgical intervention for spinal dysraphism. The admission was complicated by intermittent oxygen desaturations, suspected to be secondary to gastroesophageal reflux. UGI revealed a communication between the lower esophagus and the isolated pulmonary segment in the right medial lung base confirming a diagnosis of group III CBPFM. Conclusions: This case highlights a hybrid lesion (sequestration and CPAM) with rare communication with the gastrointestinal tract, consistent with a communicating bronchopulmonary foregut malformation (CBPFM). Vague symptoms including recurrent pneumonia and workup for feeding intolerance often lead to delayed diagnosis. Surgical excision of CBPFMs is definitive treatment; however, identification of the communicating esophageal component is necessary prior to resection. Read More

Background: Conventional medullary osteosarcoma is a malignant bone-forming tumor characterized by the production of osteoid matrix by malignant mesenchymal cells. Although it is the most common primary malignant bone tumor in children, primary osteosarcoma of the spine is exceptionally rare, accounting for less than 5% of pediatric osteosarcomas. Symptoms are frequently nonspecific, and early radiographic clues may be subtle. Due to its rarity and nonspecific presentation, spinal osteosarcomas are often diagnosed late, typically after structural destruction or neurologic compromise has occurred. Case Report: A 12-year-old female presented with two months of progressive low back pain and an unintentional 15-pound weight loss. She denied weakness, sensory loss, or bowel/bladder dysfunction. Lumbar spine radiographs revealed a lucency of the left L2 pedicle, producing a “winking owl sign.” Follow-up CT demonstrated a lytic, destructive lesion with asymmetric enlargement of the left psoas and paraspinal musculature. Additionally, CT was useful in demonstrating the presence of osseous matrix within the primary tumor. MRI revealed an expansile, enhancing lesion centered in the left posterior elements of L2, with paraspinal soft-tissue extension and circumferential epidural involvement causing moderate to severe canal stenosis. Biopsy confirmed the diagnosis of conventional medullary osteosarcoma. The patient remained neurologically intact and was referred for multidisciplinary oncologic management. Read More
