Diagnostic algorithm for glioma grading using dynamic susceptibility contrast‑enhanced magnetic resonance perfusion and proton magnetic resonance spectroscopy.

The present retrospective study aimed to investigate the diagnostic capacity of and design a diagnostic algorithm for dynamic susceptibility contrast-enhanced MRI (DSCE-MRI) and proton magnetic resonance spectroscopy (H-MRS) in grading low-grade glioma (LGG) and high-grade glioma (HGG). This retrospective study enrolled 57 patients, of which 14 had LGG and 43 had HGG, five had World Health Organization grade 1, nine had grade 2, 20 had grade 3 and 23 had grade 4 glioma. All subjects underwent a standard 3T MRI brain tumor protocol with conventional MRI (cMRI) and advanced techniques, including DSCE-MRI and H-MRS.

Splenic ectopic pregnancy: Rare location of ectopic pregnancy, how does it present?

Splenic ectopic pregnancy (SEP) is a rare high-mortality condition, particularly relating to life-threatening intraperitoneal bleeding due to a high risk of spontaneous rupture. Diagnosing in a timely fashion is extremely crucial and the patients could benefit from active treatment strategies and early management. In this article, we reviewed a case of 40 years-old female who complained of lower quadrant abdominal pain and amenorrhea with a history of intrauterine device (IUD) insertion for over 6 years.

A rare case of a primary central nervous system neuroblastoma mimicking a trigeminal schwannoma in an adult.

Neuroblastoma is a malignant extra-cranial tumor that frequently arises in the pediatric population aged <5 years but is rare in adults. Only a few cases of primary central nervous system neuroblastoma (PCN-NB) have been documented, with most occurring in young patients. In this article, we report an adult case with a PCN-NB in the cerebellopontine angle-middle cranial fossa region that mimicked another neoplasm.

Magnetic resonance imaging characteristics of glioblastoma of the optic pathway during adulthood.

Glioma has been previously known as the most common adult brain tumor. Glioma of the optic pathway is predominated by low-grade neoplasms. High-grade glioma in adults is extremely rare.

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.

Diagnostic value of 3D T1-weighted gradient-echo and 2D T1-weighted in-phase and out-of-phase gradient-echo sequences for appendicitis diagnosis in pregnant women.

Objectives: This study compared the diagnostic value of 3D T1-weighted (T1W) gradient-echo (GRE) and 2D T1W in-phase and out-of-phase GRE sequences for appendicitis diagnosis in pregnant women.

Material And Methods: This retrospective study included 25 pregnant patients with suspected appendicitis who underwent 1.5 Tesla abdominal magnetic resonance imaging and had definitive diagnoses.

Vestibular schwannoma with fluid-fluid levels mimicking aneurysm bone cyst.

Of 6%-8%, cerebral tumors are intracranial schwannomas, also known as neurinomas, which frequently arise from the nerve sheath. Eighth cranial nerve (CN VIII), also known as the vestibulocochlear nerve, is the site of genesis of the majority of schwannomas, which account for 80%-90% of cerebellopontine angle tumors. In this paper, we intended to describe an uncommon cystic vestibular schwannoma with multiple fluid-fluid levels.

Primary intraperitoneal solitary fibrous tumor in mesentery: How does it present?

Intra-abdominal solitary fibrous tumor (SFT), also known as hemangiopericytoma, is rare, especially for those with a mesenteric location, and only a few cases have been reported. Distinguishing a hemangiopericytoma from other intra-abdominal benign or malignant tumors can be difficult, as they have similar presentations on both computed tomography and magnetic resonance imaging. In the present study, the records for a 31-year-old Vietnamese woman who underwent abdominal surgery for greater omental tumor resection and received histopathological results revealing SFT are retrospectively reviewed.
