Differential Diagnosis
The patient's presentation of headaches, decreasing school performance, bilateral papilledema, and hyperreflexia after a significant fall suggests a traumatic brain injury. Given the patient's hemophilia A, there is an increased risk of bleeding complications.
Single most likely diagnosis
- E) Subdural hematoma: This is the most likely diagnosis due to the patient's history of trauma, symptoms of increased intracranial pressure (bilateral papilledema), and the presence of hyperreflexia. The initial CT scan may have missed a small subdural hematoma, which can expand over time, especially in a patient with a coagulopathy like hemophilia A.
Other Likely diagnoses
- B) Epidural hematoma: Although less likely than subdural hematoma, epidural hematoma is still a possibility, especially given the mechanism of injury and the patient's coagulopathy. However, epidural hematomas typically present with a loss of consciousness and a more rapid deterioration.
- C) Postconcussive syndrome: This diagnosis could explain the patient's headaches and decreased school performance but does not account for the bilateral papilledema and hyperreflexia, which suggest increased intracranial pressure.
Do Not Miss
- D) Subarachnoid hemorrhage: Although less likely, subarachnoid hemorrhage is a potentially life-threatening condition that requires prompt diagnosis and treatment. The patient's symptoms and history of trauma make it essential to consider this diagnosis.
- A) Brain abscess: While brain abscess is unlikely given the acute presentation after trauma, it is a serious condition that could present with increased intracranial pressure and focal neurological signs. However, the history provided does not strongly suggest an infectious process.
Rare diagnoses
- Other rare diagnoses, such as cerebral venous sinus thrombosis or traumatic arteriovenous fistula, could be considered but are less likely given the information provided. These conditions might present with similar symptoms but are less common and would require specific diagnostic testing for confirmation.
