Primary cutaneous meningioma in association with a sinus pericranii

The histopathological spectrum of cutaneous meningeal heterotopias: clues and pitfalls

“…Another argument favouring the theory of rudimentary neural tube defect in the pathogenesis of cutaneous meningeal heterotopias is the presence in some of our cases, and of published cases, of underlying RMI anomalies 24,25 . In our series, RMI seemed the most sensitive imaging technique to assess associated defects in patients with lesions suspected of meningeal heterotopias.…”

“…[6][7][8] Another argument favouring the theory of rudimentary neural tube defect in the pathogenesis of cutaneous meningeal heterotopias is the presence in some of our cases, and of published cases, of underlying RMI anomalies. 24,25 In our series, RMI seemed the most sensitive imaging technique to assess associated defects in patients with lesions suspected of meningeal heterotopias. As proposed by Bale et al, 6 we believe that cutaneous meningeal heterotopias were connected at some time with the intracranial contents through a Cutaneous meningeal heterotopias 417 bone defect which later closed, resulting in lesions with different degrees of communication with the CNS.…”

Primary cutaneous meningioma of the scalp: a case report and review of literature

“…Also, some authors have proposed that cutaneous meningiomas are not real tumors but sequestrated meningoceles or heterotopic meningeal nodules of the skin 7 . It is still possible that cutaneous meningiomas may represent direct extensions from intracranial lesions (meningiomas) either through foramina or through old operative defects into the neighboring soft tissue 1,3 …”

“…The pathogenesis of primary cutaneous meningiomas still remains uncertain. 3 This study presents a case of primary cutaneous meningioma in a newly born baby girl who presents with a subcutaneous nodule on the left posterior occipital scalp.…”

Cutaneous Meningioma

“…In one study, 28 one patient was described with both cutaneous meningioma and pheochromocytoma, although this may have been coincidental as it has not been reported since to our knowledge. Unusual presentations of cutaneous meningioma have been reported for a set of siblings with occipital tumors in nearly identical locations, 11 for a case associated with sinus pericranii (a congenital vascular anomaly), 29 and for a case involving a 3-year-old girl with an ovarian fibroma. 30 In another case, a fetus demonstrated rapid third-trimester growth, and the authors 16 concluded that this was most likely due to the influence on the tumor by endogenous steroid hormones, similar to other meningiomas.…”
