Accurate diagnosis of pulmonary inflammatory myofibroblastic tumor by imaging technology before operation: A case report

Rationale: Pulmonary inflammatory myofibroblastic tumor (IMT) is a rare borderline tumor, which has the potential of malignant including invasion of surrounding tissues, distant metastasis and recurrence. However, the preoperative diagnosis is difficult and it can also be difficult to distinguish from malignancy in small tissue samples. Preoperative accurate diagnosis has important clinical significance for patients to choose treatment measures and improve the quality of rehabilitation. We was examined by computed tomography (CT) plain scan plus enhanced scan, magnetic resonance diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) imaging technology in an adult female, compared with lung cancer and pulmonary cryptococcus infection for diagnosis of pulmonary IMT. Patient concerns: A 32-year-old female patient was admitted to the hospital "physical examination revealed nodules in the right upper lung for 1 week". Diagnoses: The patient was diagnosed with Pulmonary inflammatory myofibroblastic tumor. Interventions: Single-port thoracoscopic lobectomy was performed after multidisciplinary consultation. Outcomes: DWI and ADC improves the accuracy of preoperative diagnosis and well guides the formulation of treatment measures. The combined CT, DWI, and ADC magnetic resonance imaging technology has more important significance in the diagnosis and differential diagnosis of IMT and lung malignant tumors. Lessons: Although accurate preoperative diagnosis of pulmonary IMT is difficult. Chest CT examination combined with DWI and ADC imaging technology has high clinical significance for the diagnosis of IMT.
