The role of 3-Tesla magnetic resonance perfusion and spectroscopy in distinguishing glioblastoma from solitary brain metastasis.

Objectives: This study aimed to assess the value of magnetic resonance perfusion (MR perfusion) and magnetic resonance spectroscopy (MR spectroscopy) in 3.0-Tesla magnetic resonanceimaging (MRI) for differential diagnosis of glioblastoma (GBM) and solitary brain metastasis (SBM).

Material And Methods: This retrospective study involved 36 patients, including 24 cases of GBM and 12 of SBM diagnosed using histopathology.

Appendiceal hemorrhage: An uncommon cause of lower gastrointestinal tract bleeding and intraluminal contrast extravasation.

Lower gastrointestinal tract bleeds due to appendiceal hemorrhage are extremely rare. This emergency condition requires a multidisciplinary approach to not only give a prompt diagnosis and exclude differential diagnosis but also crucial to proceed with proper intervention and cause of bleeding. In this paper, we report a case of appendiceal hemorrhage in a young male patient who presented with lower gastrointestinal bleeding.
