TSH-secreting pituitary neuroendocrine tumor (PitNET) is one of the causes of central hyperthyroidism. The incidence of TSH PitNET is far lower than that of other PitNETs. The clinical manifestations of TSH PitNETs mainly include thyrotoxicosis or thyroid goiter, secretion disorders of other anterior pituitary hormones, and mass effect on the pituitary gland and its surrounding tissues. The application of high-sensitivity TSH detection methods contributes to the early diagnosis and timely treatment of TSH PitNETs. Improvements in magnetic resonance imaging (MRI) have advanced the noninvasive visualization of smaller PitNETs. Treatments for TSH PitNETs include surgery, drugs, and radiotherapy. This review focuses on the progress in pathogenesis, diagnosis, and treatment of TSH PitNETs to provide more information for the clinician.

Carcinomatous encephalitis is a rare entity, originally described by Madow and Alpers in 1951, which is characterized by tumoral spreading perivascular, without mass effect. Clinical manifestations such as hemiparesis, seizures, ataxia, speech difficulties, cerebrospinal fluid findings as well as computed tomography are nonspecific. This leads the physician to pursue more frequent diseases that could explain those manifestations - toxic, metabolic, and/or infectious encephalopathy. A magnetic resonance imaging (MRI) with gadolinium, the method of choice, presumes the diagnosis. Previous reports of this unusual form of metastatic disease have described patients with prior diagnosis of pulmonary adenocarcinoma. We present the case of carcinomatous encephalitis in a 76-years-old woman as the primary manifestation of occult pulmonary adenocarcinoma with its clinical, imaging, and anatomopathological findings.

Magnetic Resonance Imaging (MRI) has been the primary imaging modality and has revolutionized the imaging of brain tumors. MRI can display accurate multi planer imaging without interfering of adjacent structures specially for posterior fossa mass lesion. MRI is the imaging modality of choice for cerebollo-pontine (CP) angle Schwannoma. The study was performed to determine, the diagnostic accuracy of MRI in the evaluation of intracranial extra axial CP angle Schwannoma. MRI scan of brain was done on 42 consecutively selected patients referred for the evaluation of CP Acoustic Schwannoma. The age range from 21-60 years and the mean age was 42.85(+9.5) years. Highest incidence of cerebollo-pontine angle (CPA) mass were found 42.86% in 41-50 age group of patients. Male and Female ratio was 1.083:1. The most common presenting feature of the patients with CP angle Acoustic Schwannoma were headache 90.48%. Acoustic Schwannoma is T1 hypointense 100%, T2 hyper intense 84.61% and heterogeneously hyper intense 92.30% in FLAIR image. After giving contrast agents, homogeneous enhancement 57.69% and heterogeneous 42.31% cases of Acoustic Schwannoma. Overall 61.54% Acoustic Schwannoma strong contrast enhancement was observed. Dural tail was observed in 26.92% cases. Perilesional edema was observed 38.46% cases. Mass effect was observed in 76.92%. After complete MRI evaluation 61.9% had Acoustic Schwannoma. Histopathologicaly proved cases showed out of all patients Acoustic Schwannoma 59.52%. The overall sensitivity of MRI to diagnose Acoustic Schwannoma were found, Sensitivity- 96%, Specificity- 88.2%, PPV-92.31%, NPV-93.75% and Acceuracy 92.86%. Test is significant with p<0.0001 level. It is conceivable that MRI is a highly accurate, sensitive and Gadolinium enhanced MRI is more sensitive in detection of acoustic Schwannoma. MR imaging is the study of choice for the examination of the patient of cerebellopontine angle Schwannoma because of its high sensitivity specially after use of contrast material.

Nasopharyngeal carcinoma (NPC) is a malignant tumor of the head and neck. The primary clinical manifestations are nasal congestion, blood-stained nasal discharge, headache, and hearing loss. It occurs frequently in Southeast Asia, North Africa, and especially in southern China. Radiotherapy is the main treatment, and currently, imaging examinations used for the diagnosis, treatment, and prognosis of NPC include computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET)-CT, and PET-MRI. These methods play an important role in target delineation, radiotherapy planning design, dose evaluation, and outcome prediction. However, the anatomical and metabolic information obtained at the macro level of images may not meet the increasing accuracy required for radiotherapy. As a technology used for mining deep image information, radiomics can provide further information for the diagnosis and treatment of NPC and promote individualized precision radiotherapy in the future. This paper reviews the application of radiomics in the diagnosis and treatment of nasopharyngeal carcinoma.

Abstract Background: Pure testicular choriocarcinoma is very rare in clinic and the patient's age is 20-39 years (median age 29 years). Because of its polymorphic manifestations, it is not always suspected and patients are sometimes misdiagnosed. The case should be reported due to the rarity of the disease ,the onset age and the rapid progression of the disease. This case with primary lung cancer as the first diagnosis is a misdiagnosis. We hope we can provide some experience for clinical diagnosis and treatment. Case presentation: We report the case of a 46-year-old man who was admitted to our hospital with bloodshot sputum. Histopathological and immunohistochemical examination revealed pure choriocarcinoma. The patient had received radiotherapy, chemotherapy, immunotherapy, Over the next 5 months, the patient developed symptoms of multiple system metastases and died soon. Conclusions: Testicular choriocarcinoma is progressing rapidly. The clinical feature of choriocarcinoma is hemorrhaging at the metastatic site. Early diagnosis and timely treatment should be combined with the clinical manifestations and medical history of patients to strive for a longer survival time. We hope this case can provide guidance for the clinical diagnosis and treatment of the disease.

: Immunotherapy emerges as a treatment strategy for breast cancer marker, diagnosis and treatment. In this review, monoclonal antibodies (mAbs)-based passive and peptide vaccines as active immunotherapy approaches like activation of B-cells and T-cells are studied. Passive immunotherapy is mAbs-based therapy effective against tumor cells, which acts by targeting HER2, IGF 1R, VEGF, BCSC and immune checkpoints. Neuropeptide Y (NPY) and GPCR are the areas of interest to target BC metastases for on-targeting therapeutic action. Neuropeptide S (NPS) or NPS receptor 1, acts as a biomarker for Neuroendocrine tumors (NET), mostly characterized by synaptophysin and chromogranin-A expression or Ki-67 proliferation index. The protein fusion technologies arise as a promising avenue in plant expression systems for increased recombinant Ab accumulation and cost-efficient purification. Recently, mAbs-based immunotherapy effectiveness is appreciated as a novel therapeutic combination of chemotherapy and immunotherapy to reduce the side effects and improve therapeutic responsiveness. Synthetic drug resistance will be overcome by mAbs-based therapy through several clinical trials and detection methods need to be optimized for accuracy and precision. Pharmacokinetic attributes need to be accessed for preferred receptor-agonist activity without ligand accumulation.

Acute abdominal pain during pregnancy is challenging, both from a diagnostic and management perspective. A non-localized, persistent pain out of proportion to physical examination is a sign that advanced imaging may be necessary. Mesenteric venous thrombosis in a pregnant patient is extremely rare, but if diagnosis is delayed, can be potentially fatal to both the mother and the fetus. We present here a pregnant patient in the tenth week of gestation with classic clinical manifestations of mesenteric vein thrombosis and the corresponding findings on magnetic resonance imaging (MRI) and computed tomography (CT).

Abstract Background Early diagnosis of meningitis with magnetic resonance imaging (MRI) would be useful for appropriate and effective management, decrease morbidity and mortality, and provide better diagnosis and treatment. The objective of the current study is to compare the accuracy of contrast-enhanced FLAIR (CE-FLAIR) and contrast-enhanced T1WI (CE-T1WI) in the detection of meningeal abnormalities in suspected cases of meningitis. Results Out of 45 patients, 37 patients were confirmed to have meningitis on CSF analysis. Out of the 37 patients, 34 patients were positive on CE-FLAIR sequence and 27 were positive on CE-T1WI. The sensitivity of CE-FLAIR sequence was 91.9% and specificity 100%, while the sensitivity of CE-T1WI sequence was 73% and specificity 100%. Conclusion CE-FLAIR is more sensitive than CE-T1WI in diagnosis of meningitis. It is recommended to be used in any cases with clinically suspected meningitis.
