Inflammatory Pseudotumor of the Anterior Mediastinum Appearing as a Thymic Malignancy: Report of a Case
نویسندگان
چکیده
We treated a patient with inflammatory pseudotumor of the mediastinum that exhibited high uptake of fluorodeoxyglucose on positron emission tomography. A 69-year-old male patient was diagnosed with a mass measuring 70 mm in diameter in the anterior mediastinum as revealed by computed tomography. The lesion showed strong uptake of 18-fluorine fluorodeoxyglucose with a maximum standardized uptake value of 10.24 on positron emission tomography, which was suggestive of a thymic malignancy. Complete resection of the mass was achieved, and the postoperative pathological examination confirmed an inflammatory pseudotumor of the mediastinum arising in a perithymic lymph node. Despite its rarity, inflammatory pseudotumor should be taken into consideration when diagnosing a mass lesion with characteristics suggestive of thymic neoplasm on fluorodeoxyglucose positron emission tomography-computed tomography.

Thymic epithelial neoplasms are commonly aetiology of the anterior mediastinum masses in adults. It represents 20–30% of all mediastinal tumours in adults. Ectopic thymomas usually affect the neck, mediastinal compartments, lung, and pleura, arising from aberrant thymic tissue. For giant thymoma, there is still no consensus on the surgical approach. We herein report a patient with a giant thym...

An inflammatory pseudotumor (IPT) is a rare benign lesion, characterized by nonneoplastic proliferation of inflammatory cells and presence of intermingling collagen fibers. IPT commonly occurs in the lungs and orbita, while an intraspinal IPT is extremely rare. IPT can mimic both clinically and radiologically malignant processes, and making a definitive preoperative diagnosis is often difficult...

Inf lammatory myof ibroblast ic tumor is an unusual disease that is most commonly seen in the lung and orbit and extremely rare in the mediastinum. As far as we know, there have been only two case reports of mediastinal inf lammatory myofibroblastic tumor occurring in patients over 40 years old. In literature, we found no such case of mediastinal inf lammatory myof ibroblastic tumor that can pr...

Cervical thymic cyst is a rare entity of either congenital or inflammatory origin described infrequently in literature. The asymptomatic nature of the entity and the rarity of the lesion frequently lead to a diagnostic dilemma many times. We present a case of cervical thymic cyst that presented to us as an asymptomatic neck mass that was managed surgically. Cervical thymic cyst should be kept a...
