Successful diagnosis of diaphragmatic solitary fibrous tumor of the pleura by preoperative ultrasonography

“…The majority of patients with diaphragmatic tumors are asymptomatic, although symptoms may arise when the tumor has become large enough to exert a "mass effect" on the adjacent organs [8,10,13]. Clinical manifestations are usually related to the size of the tumor [9].…”

The vast majority of patients with tumors arising from the diaphragm do not have any specific clinical symptoms, therefore, computed tomography (CT) and magnetic resonance imaging (MRI) are the techniques required for the diagnosis. This is particularly relevant when a pathological mass has grown to an extent producing a “mass effect” on the adjacent organs. In some cases, clinical symptoms of arise due to the local invasion of the neoplasm to the adjacent tissues or distant metastases. We present a rare clinical case of a mesenchymal diaphragmatic tumor in a 34-year-old patient. After a review of her clinical status and imaging of the abdomen, including CT and MRI, the preliminary diagnosis of the gastric neoplasm of uncertain behavior (D37.1) was made, despite the initial diagnostic assumption of the exogastric location of the mass based on MRI. After careful consideration of the diagnostic assessment results, a multidisciplinary decision was made to perform laparoscopic resection of the mass. The intraoperative finding was a tumor originating from the left diaphragmatic cupula with no involvement of the stomach. The patient's recovery was uneventful. Pathological examination revealed a solitary calcifying fibrous tumor of the diaphragm. This clinical case shows that a mass arising from the diaphragm can mimic one arising from the gastric fundus, leading to an incorrect diagnosis and subsequent inappropriate management.

Solitary fibrous tumors of the pleura (SFTPs) are rare spindle cell neoplasms. The standard treatment is complete resection, but this may be challenging if the tumor is extremely large and originates from the diaphragm. We experienced a case of a giant solitary fibrous tumor originating from the diaphragm. A 74-year-old man presented with an asymptomatic giant mass on the right diaphragm suspicious of a solitary fibrous tumor. We performed a subcostal incision following posterolateral thoracotomy for complete resection. This surgical approach provided a better field around the diaphragm and facilitated radical and safe complete resection. The pathological diagnosis was a malignant solitary fibrous tumor. The patient survived for 1 year postoperatively without recurrence. We conclude that extended thoracotomy combined with a subcostal incision is a useful approach for surgical removal of giant tumors of the diaphragm.
