| | |
| | *[[Meningitis]] from infectious causes - infectious meningitis may to some degree manifest like neoplastic meningitis due to meningeal irritation. This include viral, bacterial, fungal and HIV-associated causes of meningitis. |
| | *[https://www.cedars-sinai.edu/Patients/Health-Conditions/Neurosarcoidosis.aspx Neurosarcoidosis.] |
| | *[https://www.mayoclinic.org/diseases-conditions/vasculitis/symptoms-causes/syc-20363435 Vasculitis] - the generalized nature of vessel involvement in these diseases may, to some extent involve the meninges. [[Vasculitis]] documented to present like neoplastic meningitis include [[Kawasaki disease]], [[Takayasu arteritis]], [[Polyarteritis nodosa]], [[Polyarteritis nodosa|microscopic polyarteritis nodosa]] and [[Granulomatosis with polyangiitis|Wegener granulomatosis]]. |
| | *Systemic connective tissue diseases - particularly [[SLE]] and [[Sjögren's syndrome|Sjogren's syndrome]] share some of the manifestation of neoplastic meningitis. |

| ==Differentiating [Disease name] from other Diseases==
| |
| [Disease name] must be differentiated from other diseases that cause [clinical feature 1], [clinical feature 2], and [clinical feature 3], such as [differential dx1], [differential dx2], and [differential dx3].

| [Disease name] must be differentiated from [differential dx1], [differential dx2], and [differential dx3].
| |
| | |
| OR
| |
| | |
| As [disease name] manifests in a variety of clinical forms, differentiation must be established in accordance with the particular subtype. [Subtype name 1] must be differentiated from other diseases that cause [clinical feature 1], such as [differential dx1] and [differential dx2]. In contrast, [subtype name 2] must be differentiated from other diseases that cause [clinical feature 2], such as [differential dx3] and [differential dx4].

| ===Differentiating [disease name] from other diseases on the basis of [symptom 1], [symptom 2], and [symptom 3]===
| |
| | |
| On the basis [symptom 1], [symptom 2], and [symptom 3], [disease name] must be differentiated from [disease 1], [disease 2], [disease 3], [disease 4], [disease 5], and [disease 6].
