Potential diagnostic challenges of intracerebral hemorrhage as an index presentation of metastatic choriocarcinoma: A case series.

Key Clinical Message: In young women presenting with atypical features of intracerebral hemorrhage, metastatic choriocarcinoma should be considered as a differential diagnosis. In resource-poor settings, a high index of suspicion and serum β-hCG are crucial for diagnosis. Abstract: Intracerebral hemorrhage in the young is rarely caused by metastatic choriocarcinoma. Diagnosis of this condition may be particularly challenging in resource-poor settings where access to diagnostic technologies may be limited. We present a case series of three young females diagnosed with metastatic choriocarcinoma after initially presenting with intracerebral hemorrhage, each demonstrating unique clinical manifestations. We aim to highlight the diagnostic considerations in the management of this infrequently encountered cause of intracerebral hemorrhage, especially in resource-constrained settings. Case 1 involved a 21-year-old woman who was initially diagnosed with intracerebral hemorrhage likely of tumoral origin from an unknown primary source. Further evaluation revealed extremely high levels of β-hCG and features suggestive of an intrauterine malignancy, which led to a diagnosis of metastatic choriocarcinoma. This further became complicated by pulmonary embolism. Unfortunately, she succumbed to respiratory failure during treatment. Case 2 is a young woman who presented to the emergency unit and was managed as a case of lobar intracerebral hemorrhage. Further checks revealed a previous history of hysterectomy done on account of placental site trophoblastic tumor, which promoted an evaluation for choriocarcinoma. Case 3 involved a 20-year-old patient who initially presented with headache and vomiting. An enhanced magnetic resonance imaging showed a large subacute right temporal occipital subependymal hemorrhage with mass effect. After probing further, we discovered that she underwent exploratory laparotomy for suspected ruptured ectopic gestation, which later turned out to be a gestational trophoblastic neoplasia. After further evaluation a diagnosis of choriocarcinoma with brain metastasis. Our case series emphasizes the importance of having a high index suspicion in young females who present with atypical features of ICH. The varied clinical scenarios highlight the challenges in diagnosing young females. It also underscores the critical role of serum
