Breast cancer is the most frequently diagnosed cancer in women and is caused by the uncontrolled proliferation of breast cells. Metastases from breast cancer to the central nervous system have been described frequently in the literature, but dural metastases without cerebral parenchymal involvement are rarely reported. The latter condition is known as isolated pachymeningeal metastasis (IPM). Herein, we report the case of a 52-year-old female patient who presented left homonymous hemianopia secondary to a right occipital lobe injury which was compressed by a dural thickening identified on brain MRI. Etiological investigations revealed suspicious breast lesions on chest CT scan. Anatomopathological examination of these lesions was consistent with luminal breast cancer. The diagnosis of IPM following breast cancer was confirmed, and the patient underwent chemotherapy treatment.

Genitofemoral (GF) neuralgia refers to pain and sensory complaints in the region innervated by the GF nerve. It is a rarely reported condition, often due to iatrogenic causes following inguinal surgeries. In refractory forms, diagnostic reassessment is required to look for possible entrapment of the GF nerve. Here we describe a patient who underwent appendectomy and subsequently developed severe debilitating pain in the region of the right GF nerve. Our patient underwent a second laparoscopic surgery with clip removal, resulting in rapid recovery.

Isolated downgaze paralysis is the most infrequent expression of vertical gaze abnormalities. Vertical eye movements are controlled by nuclei and circuits located in the thalamic-mesencephalon region, and more particularly the rostral interstitial nucleus of the medial longitudinal fasciculus (riMLF). The Artery of Percheron (AP) is a rare vascular anatomic variation that supplies the paramedian region of the thalami and the rostral portion of the mesencephalon. We present a unique case of isolated downgaze paralysis caused by AP ischemia.

Ulcerative colitis is an idiopathic inflammatory bowel condition that may be worsened by thromboembolic events such deep vein thrombosis, cerebral venous thrombosis, and pulmonary embolism. Cerebral venous thrombosis is a rare but critical consequence of ulcerative colitis characterized by high mortality and morbidity rate. It is thought to be caused by the hypercoagulable state that occurs during ulcerative colitis relapse. Cerebral venous thrombosis is a reversible condition with good outcomes when detected early and treated properly. In this study, we describe the case of a young woman who presented with cerebral venous thrombosis secondary to ulcerative colitis complicated by venous infarction with petechial cerebral hemorrhage.
