Restricted diffusion is frequently not present on diffusion weighted MRI. [ajnr.org]

Diffuse intrinsic pontine gliomas are diagnosed by their clinical signs and symptoms on presentation and their appearance on imaging. [ispn.guide]

Most common signs at presentation include corticospinal tract deficits, cranial nerve palsies and ataxia. [scielo.br]

At presentation, DIPG blood volume was 60 ± 27 % of that measured for normal cerebellum. Citrate, which is not detectable in normal brain tissue, was present in DIPG at concentrations of 3.81 ± 1.44 mmol/kg tissue. [ncbi.nlm.nih.gov]

• Long Tract Signs

  Patients mostly present with a short history of symptoms, typically including the classic triad of multiple cranial neuropathies, long tract signs, and ataxia. [orpha.net]

  Although the exact presentation will vary according to the location and size of the tumor, in general patients will exhibit a combination of 4: ataxia cranial nerve palsies long tract signs hydrocephalus The duration of symptoms is usually much shorter [radiopaedia.org]

  With pontine and cervicomedullary lesions, cranial nerve or long tract signs are observed commonly. Histopathologically, brainstem gliomas can range from WHO Grade 1 to 4. [emedicine.medscape.com]

  Six months later, he presented ataxia syndrome with lateropulsion, star gait, dysarthria, aphasia, vertigo, and altered mental state. MRI showed an increase in the size of the tumor to 4.7 x 3.9 x 4.1 cm. [elsevier.es]

• Dizziness

  Additionally, depending on the tumour’s localization and the patient’s age, the following symptoms can occur: rapidly increasing head-circumference (macrocephalus), developmental delay, headaches, backaches, nausea and vomiting in the morning, dizziness [kinderkrebsinfo.de]

An additional challenge in the treatment of DIPG is that the blood-brain barrier (BBB) often limits the efficacy of chemotherapeutic regimens in the treatment of DIPG, which has therefore caused radiation therapy to remain the mainstay of treatment. [news-medical.net]

Nanotechnology may offer therapeutic options for the treatment of DIPGs. Multiple nanoparticle formulations are currently being investigated for the treatment of DIPGs. [eurekaselect.com]

Treatment and prognosis Again, both treatment and prognosis are significantly influenced by tumor type, morphology and location. Radiation is a key part of treatment as surgical resection is usually not possible. [radiopaedia.org]

[…] of Pontine Glioma poor prognosis prognosis is tried to improve prognosis with therapy-optimising studies and preospective studies [hirntumorhilfe.org]

Due to the poor prognosis of diffuse intrinsic pontine gliomas, the limited therapy options, the relevant portion of EGFR expression and the unexpected good response to the therapy with OSAG 101 in the phase II study, a phase III study was planned in [clinicaltrials.gov]

How much of this variation is due to artifactual influences or etiologic differences has been the subject of many debates. Some reports have suggested a slight male preponderance, whereas others have failed to observe any sex predilection. [emedicine.medscape.com]

Within the umbrella of adult brainstem glioma, there is a subset of tumors that is similar in appearance and potentially similar in etiology to childhood DIPG, but with slightly older onset, generally affecting young adults. [frontiersin.org]
