“…We suggest that primary pulmonary meningiomas reported to date are a giant form of PMN. In previous reports on solitary primary pulmonary meningiomas [13, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35], newer markers such as PR and CD56 had not been evaluated ( table 2 ). Given the similarity of the immunohistochemical results of our case to reported minute PMNs, including the positive PR and CD56 staining [1, 14], these previously reported primary pulmonary meningiomas may include a similar disease entity.…”

Minute pulmonary meningothelial-like nodules (PMNs) are asymptomatic, small nodules that are occasionally detected in surgical or autopsy specimens. Recent improvements in tumor imaging and the increased use of computed tomography (CT) scans of the chest have led to the early detection of these pulmonary nodules in various clinical settings, often before surgery or health examinations. However, large PMNs have rarely been observed. In this study, we report a patient with a large PMN, which was almost identical to so-called ‘primary pulmonary meningioma’. A CT scan of his chest revealed a small, well-circumscribed nodule. Immunohistochemical analysis of the tumor revealed that the tumor cells were positive for CD56, epithelial membrane antigen, and progesterone receptor. Given the similarity of these results to the staining pattern of minute PMNs in previous reports, we suggest that the primary pulmonary meningiomas reported to date are, in fact, a giant form of PMN.

“…Although primary pulmonary meningiomas arising from ectopic arachnoid cells in the lung have been reported, our patient's atypical features on histology coupled with the aggressive nature of his meningioma requiring numerous surgical interventions probably led to the haematogenous metastatic spread to the pleural cavity 14 15…”

A 32-year-old man was admitted with cerebrospinal fluid leakage from a right scalp surgical wound after a resection of recurrent meningioma and reconstruction of skull with muscle flap 3 weeks earlier. On day 4 of admission, he was found to be tachycardic and decreased breath sounds on the right side. Chest x-ray revealed a large right pleural effusion which was found to be exudative after thoracocentesis. Infectious work-up and cytology was negative. CT showed both parietal and visceral pleural masses, which was consistent with meningioma on ultrasound-guided biopsy. He underwent right-side decortication and pleurodesis for recurrent pleural effusion. He declined further treatment and opted for hospice care and expired a month later.

“…Moreover, this condition has no characteristic imaging finding, and primary lung cancer or metastasis is commonly suspected on imaging; benign primary pulmonary meningioma is generally well circumscribed in radiological studies. [ 8 ] Previous reports of primary pulmonary meningioma with contrast-enhanced CT images showed various enhancement patterns, such as heterogeneous or nodular enhancement, [ 12 , 13 ] poor enhancement, [ 14 , 15 ] or homogeneous enhancement. [ 2 , 16 , 17 ]…”

Rationale:Primary pulmonary meningiomas are extremely rare, and only a few cases have been reported in the medical literature. Imaging findings of primary pulmonary meningiomas have been reported even more rarely.Patient concerns:We present the case of a 54-year-old male patient with cough and sputum lasting for 20 years. This was a case of primary pulmonary meningioma with initial suspicion of a chest wall intercostal neurinoma.Diagnoses:A lung lesion was detected on chest computed tomography (CT) imaging 4 years ago. This case appeared as a solitary well-defined round nodule close to the left chest wall, with heterogeneous enhancement on CT, which inaccurately led to the suspicion of a chest wall intercostal neurinoma.Interventions:A thoracoscopic wedge resection was performed.Outcomes:The postoperative histological diagnosis was primary pulmonary meningioma. After 2 years of follow-up, the patient is still alive without evidence of metastasis or recurrence.Lessons:Increased awareness of the CT characteristics of this rare tumor may broaden the radiologist's knowledge base.
