Six patients with small cell lung cancer developed a slowly progressive neurologic syndrome characterized by apathy, abulia, memory loss, gait ataxia, and corticospinal tract signs 26 to 50 months (mean, 35.2 months) after prophylactic cranial irradiation and systemic chemotherapy. In each case this was accompanied by CT and/or MRI evidence of changes in the periventricular white matter. These patients are long-term survivors (41 to 69 months) and do not have CNS metastases.

Three patients with hydrocephalus secondary to central nervous system (CNS) metastases from lung or breast cancer are reviewed representing less than 5% of patients with CNS metastases seen at The Cancer Center of Boston over a 10-year period. The clinical picture is characterized by ataxia and mental confusion with dilated ventriculi on computed tomography (CT) scan of the brain. Computerized tomography of the brain and microscopic analysis of the cerebrospinal fluid are complementary in establishing the diagnosis of meningeal carcinomatosis. Surgical management by ventricular peritoneal shunt is an important component to multimodality therapy. The clinical course and extended survival in three patients provides a basis for recommending palliative surgical bypass as a therapeutic intervention with or without intrathecal chemotherapy, radiation, or both.

Transitional cell carcinoma of the bladder (TCC) represents nearly 90% of genitourinary malignancies and typically presents with locally invasive symptoms. Metastasis to the central nervous system (CNS) is uncommon occurring in <5% of patients. When present, metastatic lesions are typically solid, isolated and located in the cerebrum. We report a case of a patient with a history of TCC who presented with lethargy and ataxia and was found to have a solitary cystic cerebellar lesion consistent with metastatic disease. Unfortunately, the prognosis for patients with TCC and CNS metastases is poor. Treatment options include debulking surgery, whole brain radiation, stereotactic radiosurgery and chemotherapy. Unfortunately, treatment may not appreciably extend survival and care is often supportive in previously reported cases. Though uncommon, TCC can metastasise to the CNS and should be considered in the differential diagnosis of patients, particularly those who were treated with aggressive surgery or combination chemotherapy previously.

The development of brain and central nervous system (CNS) metastases from primary gynecologic cancers is an extremely uncommon but deadly process. Through this retrospective case series of patients treated at a single institution from 2004 to 2018, we aim to explore potential clinical patterns of this phenomenon with respect to primary tumor type, histology, and symptomatology. A total of 42 patients were identified with CNS metastases, with 24 patients having endometrial cancer, 9 patients with ovarian cancer, 5 patients with cervical cancer, and 4 patients with gestational trophoblastic neoplasia (GTN). The two most common presenting complaints were headache and ataxia. Most patients (67%) presented with more than one lesion on imaging and the frontal lobe was most likely to be involved. The median age of diagnosis for both primary cancer and CNS metastasis were significantly younger in the GTN group when compared to other cancers. Meningeal involvement was more prevalent in patients with cervical cancer. Over 83% of endometrial cancer patients in this cohort had type II histologies, a significantly higher percentage than that in the general population. While the rarity of CNS metastases in primary gynecologic malignancies precludes routine screening, patients diagnosed with more aggressive histologic subtypes of endometrial and uterine cancers may benefit from a lowered threshold of brain imaging in the context of new onset neurological symptoms.
