Plurihormonal ACTH-GH Pituitary Adenoma: Case Report and Systematic Literature Review.
Plurihormonal adenomas (PHAs) represent 10%-15% of all functioning pituitary adenomas. The most frequent hormonal associations are with prolactin and growth hormone (GH). Here we describe a rare case of functional adrenocorticotropic hormone (ACTH) and GH microadenoma and report our findings from a systematic literature review of PHA. ⋯ This is an additional case to the 20 previously reported cases of ACTH-GH PHA. Awareness of this relatively rare entity is clinically relevant. The cytogenesis of ACTH-GH PHA remains a matter of debate, and several hypotheses have been postulated.

The Pathogenesis of Subacute Subdural Hematoma: A Report of 3 Cases and Literature Review.
To discuss the pathologic mechanism of subacute subdural hematoma (sASDH). ⋯ The conversion of acute subdural hematoma to sASDH is an inflammatory reaction process with very regular in time, and it is speculated that the pathologic mechanism may be a delayed hypersensitivity reaction. Antigen released during the liquefaction process of blood clot, with subdural neomembrane cells as antigen-presenting cells, is presented to the T lymphocytes released from the capillaries in the neomembrane and forms sensitized T lymphocytes. When the subsequent antigen is released from the blood clots with a delayed liquefaction and is exposed to sensitized T lymphocytes, the delayed hypersensitivity process occurs.

Spontaneous Intraventricular Tension Pneumocephalus: Case Report and Review of the Literature.
Intracranial pneumocephalus is a well-known clinical entity most frequently caused by trauma and intracranial surgery. A less frequent cause of intracranial pneumocephalus is spontaneous pneumocephalus. Spontaneous pneumocephalus can have an intraventricular extension, causing tension intraventricular pneumocephalus. ⋯ This case demonstrates an unusual presentation of spontaneous intraventricular tension pneumocephalus necessitating ventriculostomy in addition to the traditional repair of a cerebrospinal fluid fistula.

Endovascular Recanalization of Occluded Dural Sinus in Patient with Dural Arteriovenous Fistulas: Case Report and Literature Review.
Symptomatic sinus occlusion complicated with dural arteriovenous fistulas (dAVFs) can be treated successfully endovascularly. However, no studies have reported the use of endovascular transvenous approaches alone to recanalize the occluded sinuses for treatment of the involved dAVFs without stent deployment. In this study, we presented a 75-year-old man with occlusion of the transverse and sigmoid sinuses complicated with a dAVF. ⋯ Endovascular transvenous recanalization may be a better alternative therapy for selected patients with dural arteriovenous fistulas complicated by sinus occlusion without stent deployment.

Primary Spinal Malignant Mesothelioma: A Case Report and Literature Review.
Malignant mesotheliomas are aggressive and rapidly fatal neoplasms arising from the mesothelial cells. The most common sites of origin are the pleural and peritoneal cavities; the pericardium and the tunica vaginalis are infrequently involved, and malignant mesothelioma in the spinal canal is extremely rare. Here we report a case of primary spinal malignant mesothelioma. We also report the results of a literature search conducted in PubMed with specific key terms, inclusion criteria, and exclusion criteria, with a comparison of elected case studies and case series, and statistical analysis as appropriate. ⋯ Spinal malignant mesothelioma is an extremely rare but highly aggressive entity. Preoperative identification is challenging, and definitive diagnosis depends on histopathological evidence. Surgical resection can help relieve the symptoms, but the overall prognosis is poor.
