Objectives. Leptomeningeal metastasis (LM) of primary uterine cervical cancer is rare and treatment options are limited. In this case report literature review, we aimed to present a patient with LM discuss previously reported cases in the literature. Case presentation. Our was 58-year-old who initially diagnosed metastatic treated chemotherapy chemoradiotherapy. During follow-up, she developed ...

Pineal parenchymal tumors are rare. Of the three types of pineal parenchymal tumors, pineocytomas are the least aggressive and are not known to diffusely disseminate. In this paper, we report the successful treatment of a case of pineocytoma with diffuse leptomeningeal relapse following initial stereotactic radiotherapy. A 39-year-old female presented with headaches, balance impairment, urinary...

Primitive neuroectodermal tumors (PNETs) are easily detected, and the diagnosis made by neuroradiologic imaging. Leptomeningeal seeding is a common complication and carries a poor prognosis. Primary leptomeningeal PNETs are rarer and difficult to diagnose on magnetic resonance imaging (MRI) or cerebrospinal fluid (CSF) studies. We encountered a rare case of primary leptomeningeal primitive neur...

Pilocytic astrocytomas correspond to low-grade gliomas and therefore metastasize exceedingly rare. However, pilocytic astrocytomas are able to and leptomeningeal dissemination may be seen. What are the treatment options of these cases? We present a case report of a 3-year-old child with a pilocytic astrocytoma of the optic chiasm with leptomeningeal dissemination of the spinal meninges. Partial...

Carcinomatous meningitis, specifically leptomeningeal metastases from solid tumors, has a dismal prognosis, with an overall median survival of 2 to 4 months. Lymphomatous meningitis has a better outlook, with a median survival of more than 6 months, but diagnosis may be delayed and treatment is not curative. Despite these poor statistics, there are subsets of patients who do relatively well. Mo...

A 20-year-old male patient was admitted to our clinic with a 1-year history of headache. The patient’s systemic-neurological examination and laboratory findings were normal. Computed tomography and magnetic resonance imaging were performed. Imaging findings showed calcified intraventricular mass and subependymal and gyral nodular lesions. There was a slight increase in ventricular volume. Surgi...

BACKGROUND This review seeks to provide a structured presentation of existing knowledge of leptomeningeal anastomoses from anatomic and functional points of view and to identify problems and possible research directions to foster a better understanding of the subject and of stroke mechanisms. SUMMARY OF REVIEW Available data show that leptomeningeal anastomoses may be important in understandi...
