Meningeal Carcinomatosis for Prostate Adenocarcinoma Mimicking Chronic Subdural Hematoma: Case Report and Literature Review (original) (raw)

Subdural Hematoma Secondary to Brain Metastasis in a Prostate Cancer: A Cadaveric Finding

International Journal of Anatomy and Research, 2016

Brain metastasis is rare occurrence with metastatic prostate cancer whereas bones, lung, pleura are the most common organs to be involved. During our cadaver dissection, it was found that the patient had a subdural hematoma secondary to brain metastasis as a result of metastatic prostate cancer. The case report presents with the dissection of Brain showing clear cut midline shift and Obliteration of anterior and posterior horn of ventricles. The symptoms in brain metastasis may not occur initially but may appear in late involvement. SubDural hematoma is of common occurrence in andropause age group especially who are receiving anti-coagulants or had minor head injury. The incidence of brain metastases may be increasing due to better imaging techniques. In such patients, use of anti-coagulants, anti-platelets or anti-VEGF therapy can increase the risk of intracranial hemorrhage hence used with caution.

Meningeal Carcinomatosis in Metastatic Prostate Cancer: A Case Report

The Prostate Journal, 1999

Leptomeningeal involvement of metastatic prostate cancer is a rare clinical entity. We report such a case, along with a summary of three previous cases where detailed clinical information is available. Seven additional cases (for a total of 10 cases) have been reported previously in the literature. It seems that this syndrome is associ-ated with changes in mentation, specifically without cranial nerve findings on physical exam. The physician should be alerted to the possibility of this clinical circumstance in metastatic prostate cancer patients with altered mental status.

Metastatic Adenocarcinoma of the Prostate to the Brain Initially Suspected as Meningioma by Magnetic Resonance Imaging

Cureus, 2020

Brain metastasis from prostate cancer is rare, occurring in less than 1% of metastatic prostate cancer patients. Brain metastasis can cause edema, neurologic symptoms, and may be misdiagnosed as primary brain tumors on imaging. A 68-year-old male presented to the emergency department complaining of headaches, right-sided weakness, multiple falls, and a 45 pounds of unintentional weight loss. Computerized tomography (CT) scan without contrast of the head showed a 3.2 cm right frontal mass with edema suspicious for meningioma. Associated nonspecific bony lesions were found on CT of the abdomen and pelvis. Magnetic resonance imaging (MRI) of the brain showed a 2.8 cm right frontal mass with an enhanced dural tail. Preoperative labs were noteworthy for a hemoglobin of 9.7 and prostate-specific antigen (PSA) of 66.7 ng/ml. Craniotomy with resection of tumor was performed with a frozen sample diagnosed as meningioma. Permanent pathology with stains were positive for PSA and prostatic-specific acid phosphatase (PSAP), making the diagnosis of metastatic prostate adenocarcinoma. Postoperatively, nuclear bone scan showed uptake in the axial skeleton consistent with metastasis. After the diagnosis of metastatic prostate cancer was made, bicalutamide was administered followed by degarelix with plans to transition to leuprorelin one month later. This is to be followed up by whole brain radiation therapy (WBRT). PSA was 118.53 ng/ml three weeks after craniotomy, but prior to androgen deprivation therapy. Metastatic prostate cancer can present with neurological symptoms most commonly following spread to the axial skeleton and impingement of the spinal cord. Metastasis to the brain is rare and is usually associated with vague symptomatology depending on extent and location of the lesion. While brain metastasis can occur in known prostate cancer patients, this case shows that metastasis can occur prior to any formal prostate cancer diagnosis and can be mistaken for meningioma on imaging and frozen sectioning. Practitioners must be vigilant, and precautions should be taken to rule in metastatic prostate cancer as a possible cause for a brain lesion in patients of the appropriate demographics.

Metastatic prostate adenocarcinoma to intradural foramen magnum

Journal of Surgical Case Reports, 2017

Intradural metastatic tumors are rarely reported in foramen magnum (FM), including cases of melanoma, pituitary carcinoma, thyroid carcinoma, and prostate carcinoma metastases. We report a 68-year-old male who presented with right-sided headache, progressive swallowing difficulty requiring gastrostomy tube and hoarseness over the course of 1 year. Images revealed a heterogeneous, contrast-enhancing lesion in the FM that compressed the anterior aspect of the medulla and upper spinal cord. Although metastatic tumor was considered in differential diagnosis, presumptive diagnosis was FM meningioma due to lack of bone destruction or sclerosis on CT and T2W isointense and T1W hypointense appearance on MRI. The patient underwent gross total resection via right far-lateral transcondylar approach. Histopathological examination revealed prostate carcinoma metastasis. To the best of our knowledge this is the second case report of an intradural prostate carcinoma metastasis in the FM.

Dural Metastasis with Subdural Hemorrhage from Prostate Cancer

International Journal of Neurologic Physical Therapy, 2017

A subdural hematoma (SDH) is usually traumatic in etiology. Non-traumatic instances of SDH are uncommon, and are rarely due to metastases involving the dura. We report a 68-year-old male patient with a one day history of, not communicating and not mobilizing and a 2 weeks history of generalized body weakness. A computed tomography (CT) scan revealed a left sided hypo-dense subdural collection. A diagnosis of left sided chronic subdural hematoma (SDH) was made. Burr hole drainage of the hematoma was performed. Intra-operatively, liquefied blood was drained and a thick dura with reddish material infiltrating the dura was noted. A specimen of the dura was submitted for histology and revealed metastatic carcinoma, confirmed at immunohistochemistry to be of prostatic origin. Conclusion: Metastatic disease should be considered when there is a chronic subdural hematoma with no history of trauma and an unusual dural appearance on imaging.

Metastatic prostate adenocarcinoma invading an atypical meningioma

Journal of Clinical Neuroscience, 2011

Although prostate adenocarcinoma is the most commonly diagnosed cancer in men, intracranial metastases are rare. We describe a 72-year-old patient with known metastatic prostate cancer, presenting with a dural-based parafalcine lesion on radiological imaging, following a seizure. Total macroscopic excision of the lesion was achieved at surgery, with histopathology confirming prostate adenocarcinoma embedded in an atypical (World Health Organization Grade II) meningioma, fulfilling all the criteria for true tumour-to-tumour metastasis. To our knowledge, this is the first report of prostate cancer metastasising to an atypical meningioma.
