“…After contrast medium administration, the enhancement pattern is variable. Strong and homogeneous enhancement has been reported [1]. As in our case and in previously reported cases, when patients have a history of malignant tumor, PPM or isolated metastasis may not be distinguishable only on radiologic images.…”

Primary pulmonary meningiomas represent a rare tumor entity. Few cases have been reported in the English medical literature, and they have almost all been solitary and benign in nature, with the exception of several extremely rare cases. We report herein a case of PPM that raised suspicion of a pulmonary metastatic tumor initially, as it was depicted as a single, round, small, ground-glass opacity pulmonary nodule on a chest computed tomography scan, in a 55-year-old man with a history of buccal cancer. Increased awareness of the clinical and radiologic characteristics of this rare category can assist a multidisciplinary team to perform adequate management.

“…Only 45 cases were described in the English medical literature to 2015 [1]. Most of these were solitary and benign in nature, and fewer than five cases have been reported to be malignant, with only one case of autopsy-proven liver metastasis [2–4].…”

“…[6] Though a primary pulmonary meningioma may remain asymptomatic and be found incidentally, [7,8] atypical chest pain was present for more than 1 year in our case. Kim et al [4] have also recently reported a case of a primary pulmonary meningioma in a 61-year-old female with a typical chest pain. A primary pulmonary meningioma is largely benign, grows slowly, and has an excellent prognosis.…”

Rationale:Primary extracranial meningiomas are rare outside the head and neck region.Patient concerns:A 44-year-old female patient had chest pain for more than 1 year.Diagnoses:Preoperative chest computed tomography (CT) scan revealed a nodule in the right lower lobe, 1.8 cm in diameter. Tumor tissues were examined by immunohistochemistry for vimentin and S-100.Interventions:Histopathologically, the tumor was characterized by whorled nests of spindle-shaped cells accompanied by psammoma bodies. Immunohistochemistry demonstrated tumor cell positivity for vimentin and S-100. This case was diagnosed as a primary pulmonary meningioma. The tumor was removed by a thoracoscopic pulmonary wedge resection.Outcomes:Postoperative cranial and spinal CT scan did not show any intracranial or spinal mass. No recurrence of the tumor was reported at the time of writing up this case report.Lessons:A primary pulmonary meningioma should be considered in the differential diagnosis workup of pulmonary nodules.

“…Then in 2010, we also reported the additional clinical course in the initial case 10 years after surgery implying a benign biological nature [2]. There have been fewer than 50 cases of PPMs reported in the literature to date [3], [4]. Although the lesions are widely known most likely to be benign, grow slowly, and have an excellent prognosis, the etiology is still uncertain; and hence, several mechanisms have been proposed [1], [4], [5], [6], [7], [8].…”

HighlightsAn 84-year-old Japanese woman with a history of multiple primary meningiomas (PPMs) we first reported.Histologically confirmed for a right-sided slowly growing lung nodule for 20 years.Long-term follow-up CT scans reveal multiple lung nodules.Multiple PPMs are most effectively treated with surgical resection and follow-up examinations.The tumors prove to be benign by morphology with a relatively long, asymptomatic clinical course.
