Sarcomas are a diverse group of cancers of mesenchymal origin. Epithelioid inflammatory myofibroblastic sarcoma (EIMS) is an uncommon and hardly reported neoplasm that is a malignant variant of the typically benign inflammatory myofibroblastic tumor (IMS). We discuss an exceedingly rare case of a 53-year-old patient with primary EIMS of the pericardium who presented in impending hemodynamic collapse. A transthoracic echocardiogram revealed a large circumferential pericardial effusion with tamponade physiology and an echogenic intrapericardial mass compressing the right ventricle to near obliteration. She underwent emergent sternotomy with resection and one cycle of chemotherapy with liposomal doxorubicin before having recurrent metastatic pericardial and pleural effusions, ultimately leading to her unfortunate passing.

We present a case of gonococcal septic arthritis of the right hip diagnosed via synovial fluid cultures. Antimicrobial susceptibility testing of the synovial fluid demonstrated susceptibility to tetracycline, ciprofloxacin, cefixime and ceftriaxone. Our patient was initially treated with ceftriaxone and was successfully de-escalated to oral levofloxacin to complete the treatment. This case is interesting given the rarity of disseminated gonococcal infections in the 21st century and that most clinical isolates of Neisseria gonorrhoeae are increasingly resistant to fluoroquinolones.

An elderly female presented to the emergency department with a right-sided facial droop and headache for two weeks. Investigations revealed poorly controlled diabetes, and the patient was found to be in diabetic ketoacidosis. Maxillofacial computed tomography (CT) demonstrated right postseptal cellulitis with concern for acute invasive fungal sinusitis. The patient was taken to the operating room for orbital surgical exploration and antrostomy. Surgical pathology revealed broad hyphae consistent with Rhizomucor species, and the patient was diagnosed with mucormycosis. Because the patient was not clinically improving, further imaging was obtained, which showed a large right retroantral phlegmon extending into the cranial fossa and right cavernous sinus, and the patient subsequently underwent surgical debridement. The following postoperative day, the patient was stroke-alerted due to altered mental status and inability to follow commands. She was found to have a small embolic infarct. Due to the poor prognosis of the patient, she was discharged with hospice. Mucormycosis is more commonly found in immunocompromised patients, such as those with uncontrolled diabetes mellitus but very rarely does it involve the cranium. This disease process is very important to recognize early due to high morbidity and mortality rates and devastating outcomes.

Leptomeningeal metastasis (LM) is an outcome associated with a terminal prognosis for a patient with metastatic cancer. Symptoms associated with this type of cancer progression can be subtle and nonspecific. Evaluation of LM occurs with a lumbar puncture (LP) and magnetic resonance imaging (MRI). Guillain-Barre Syndrome (GBS) can present with a similar presentation of neurological symptoms to LM. Additionally, both disease states may present with similar MRI findings. The LP can be an important diagnostic evaluation to differentiate LM and GBS. However, an LP may be unremarkable in both disease states. Therefore, a comprehensive assessment of the patient based on clinical history, physical examination, laboratory, and radiologic evaluation is essential for prompt diagnosis and treatment. We present a patient with metastatic breast cancer that presented with generalized weakness. Thorough evaluation allowed the diagnosis and treatment of GBS.
