Neurocysticercosis Presenting as Migraine in the United States.

BACKGROUND Cysticercosis is a condition caused by infection with the larval form of Taenia solium, a pork tapeworm that uses pigs as an intermediate host. Humans become infected when they ingest water or food contaminated with tapeworm cysts. Cysticercosis is increasing in frequency in developed countries due to increased access to travel. Neurocysticercosis occurs when Taenia solium cysts embed within the nervous system. The clinical presentation of neurocysticercosis ranges from asymptomatic to life-threatening, largely depending on the brain parenchymal involvement. The diagnosis is typically made with a combination of clinical evaluation, serology, and neuroimaging. Treatment for parenchymal neurocysticercosis may involve anthelmintic agents, symptomatic agents, surgery, or a combination of methods. CASE REPORT A 52-year-old man with a medical history of migraine headaches, complicated type 2 diabetes mellitus, and obesity presented with a 4-month change in his migraines becoming severe, worse over his occiput bilaterally, and unresponsive to abortive therapy. His exposure history was unremarkable except for a habit of eating undercooked bacon, by which he would have developed neurocysticercosis via autoinfection. Neuroimaging and serology confirmed a diagnosis of neurocysticercosis and he was treated accordingly with antiparasitic and anti-inflammatory medications. CONCLUSIONS This presentation is nonspecific and can easily be overlooked, especially if there is an underlying known neurological condition such as migraine. This case illustrates that neurocysticercosis should be considered when an existing neuropathological condition displays a change in presentation or requires a change in therapeutic management, even without obvious risk factors.

A Rare Case of Severe Stevens-Johnson Syndrome Triggered by Topical Ofloxacin.

BACKGROUND Stevens-Johnson syndrome (SJS) is a rare dermatologic disorder that is characterized by nonspecific flu-like prodrome with fever, malaise, myalgia, cough, rhinitis, and sore eyes, followed by a characteristic rash and mucocutaneous manifestations. It is triggered by medications in up to 80% of cases in adults. In each of these cases, the medication is oral or parenteral. Severe and progressive SJS can result in life-threatening complications. Adult-onset medication-induced SJS presents within 8 weeks of exposure to the offending substance, lasting 8 to 12 days. Recovery of denuded skin generally is complete within a month. There is no consensus on treatment, but supportive care with corticosteroids is often the initial intervention. CASE REPORT A 36-year-old woman with a flare of allergic rhinitis and tearing resistant to over-the-counter options was treated with topical ophthalmic ofloxacin. She began experiencing a diffuse mucocutaneous rash, with oral desquamation, tongue swelling, vaginal desquamation, and rash of the palms and soles within 24 h, which suggested the possibility of SJS. A skin biopsy was obtained, and pathology confirmed this suspicion. She was treated with parenteral antibiotics, corticosteroids, and supportive care, and after 10 days was discharged from the hospital. She had a complete recovery in 30 days. CONCLUSIONS The clinical course of SJS induced by the ophthalmic application of medication can be just as severe as the oral or parenteral routes. This is, to the best of our knowledge, the first documented case of SJS being triggered by topical ofloxacin.

Ovarian Vein Thrombosis: An Unusual Cause of Abdominal Pain in Breast Cancer.

Ovarian vein thrombosis (OVT) is a rare but potentially life-threatening complication that is usually seen in the intrapartum or postpartum period but can also be seen in patients with risk factors for venous thromboembolism. When symptomatic, it usually presents with abdominal pain and other vague constitutional symptoms, hence it is important for healthcare professionals to be aware of this condition when evaluating patients with risk factors. We present a rare case of OVT in a patient with breast cancer. Due to a lack of clear guidelines regarding the treatment and duration of treatment in non-pregnancy-related OVT, we followed the guidelines for the treatment of venous thromboembolism and started the patient on rivaroxaban for a three-month duration with close outpatient follow-up.

A 24-Year-Old Man Presenting with Lung Metastases from a Primary Retroperitoneal Extragonadal Choriocarcinoma.

BACKGROUND Primary retroperitoneal choriocarcinoma is a rare form of extragonadal germ cell tumor that is highly aggressive and responds poorly to chemoradiation. Extragonadal choriocarcinomas are notoriously challenging to diagnose, and have often progressed to advanced disease by the time of diagnosis. The survival rate for extragonadal choriocarcinoma is approximately 30%, which is much lower than that of extragonadal non-seminomatous germ cell tumors (GCT) in general. CASE REPORT A 24-year-old man with no significant past medical history presented with left-sided, pleuritic chest pain and back pain radiating down his left leg, of 1-year duration. Computed tomography (CT) of the chest revealed multiple bilateral pulmonary nodules and a CT of the abdomen and pelvis showed a large heterogeneous soft tissue mass measuring 9.3×8×10.5 cm. A CT-guided core needle biopsy of a lung nodule was performed and the findings were consistent with the diagnosis of metastatic choriocarcinoma. Magnetic resonance imaging (MRI) of the brain was negative for metastatic disease. Tumor markers were significant for a markedly elevated beta human chorionic gonadotropin (B-hCG) of 104 712 mIU/mL. He was diagnosed with a stage IIIC germ cell tumor, further classified as a primary retroperitoneal choriocarcinoma with lung metastasis, and was started on urgent inpatient chemotherapy. CONCLUSIONS Due to the poor outcomes associated with extragonadal choriocarcinoma, it is important to promptly and correctly identify this malignancy in order to initiate treatment in a timely manner. The following case report explores the histopathologic characterization of this malignancy and describes the clinical course and outcomes from treatment for this patient.

Systemic Lupus Erythematous and Neuromyelitis Optica Causing Hypercapnic Respiratory Failure.

BACKGROUND Neuromyelitis optica (NMO) is a rare neurological disease characterized by attacks of transverse myelitis and optic neuritis, contiguous spinal cord lesions on more than 3 vertebral segments on magnetic resonance imaging (MRI), and seropositivity for AQP-4 Ab. The tissue destruction from NMO is immune mediated and results in demyelination and axonal damage. Optic and spinal nerve involvement can eventually lead to blindness, weakness, and altered consciousness, and bladder and bowel involvement in some cases. CASE REPORT A 54-year-old Black woman presented with chest pain, dysphagia, generalized weakness, diplopia, and paresthesias in her bilateral feet. A brain MRI revealed an area of hyperintensity in the cervical medullary junction. A diagnosis of NMO was made after the treatment response was poor for systemic lupus erythematous (SLE) myelitis. She eventually developed acute hypercapnic respiratory failure, became encephalopathic, and was emergently intubated. She was extubated but had poor recovery and was eventually discharged home. CONCLUSIONS NMO is a rare immune-mediated disease that is often delayed in diagnosis and treatment. Clinical suspicion is important since there is a tendency for the disease to overlap concomitant autoimmune diseases in 25% of cases. Progressive and permanent tissue damage can occur despite the use of high-dose steroids, long-term immunosuppressant agents, immunomodulators, exchange transfusions, and even autologous hematopoietic stem cell bone marrow transplantation.

Acute Hepatitis E: A Rare Cause of Acute Liver Failure in a Patient With Acute Myeloid Leukemia.

Immunocompromised patients are particularly at risk to develop hepatitis E virus (HEV) infection and its related complications. We present a rare case of HEV infection in a 35-year-old Hispanic female with concomitant acute myeloid leukemia (AML). The patient presented with acute liver failure within a few weeks after receiving a blood transfusion. Our case likely represented an acute de novo HEV infection after chemotherapy in a patient with concurrent AML, evidenced by the presence of anti-HEV IgM antibodies as well as histological findings, and with a previous history of recent transfusions being one of the strongest risk factors for transmission. Liver failure from an acute de novo hepatitis E infection with concurrent AML can be catastrophic in the immunosuppressed patient. Our case is particularly unique due to the uncommon presentation of acute hepatitis E in a non-pregnant reproductive aged Hispanic female with recently diagnosed AML. Clinicians should maintain a low threshold to test serum HEV-RNA if a patient presents with signs and symptoms suggestive of acute hepatitis.

Portal vein aneurysm with acute portal vein thrombosis masquerading as a pancreatic mass.

Portal vein aneurysm (PVA) with portal vein thrombosis (PVT) is an exceedingly rare vascular phenomenon with a limited number of reported cases in the medical literature. We describe a case of a 25-year-old man found to have a congenital PVA with PVT initially believed to be a pancreatic mass. While there remains some incongruity amongst clinicians with such a limited number of reported cases, herein, we describe the general consensus of the diagnostic approach and management of this vascular malformation.

Vaping-Induced Lung Injury: A Case of Lipoid Pneumonia Associated with E-Cigarettes Containing Cannabis.

Electronic cigarette, or vaping product use-associated lung injury (EVALI), is a group of lung disorders associated with vaping and e-cigarette products that has previously been categorized as a diagnosis of exclusion and best described as an exogenous lipoid pneumonia or chemical pneumonitis. Here, we describe the onset of an exogenous cause of lipoid pneumonia in an otherwise healthy patient using cannabis-containing electronic cigarettes. We explore similarities in the clinical case, define a common clinical presentation with progression of disease, characteristic radiographic findings along with pathological diagnosis and management.

Thrombocytopenia and endocarditis in a patient with Whipple's disease: case report.

BACKGROUND: Whipple's disease (WD) is a rare multisystem infectious disorder that is caused by the actinomycete Tropheryma whipplei. It presents with joint pain followed by abdominal pain, diarrhea, malabsorption and finally failure to thrive. Diagnosis requires tissue sampling and histology with periodic acid-Schiff [PAS] staining. Thrombocytopenia associated with endocarditis associated with WD has been reported twice. CASE PRESENTATION: A 56 year old Caucasian male presented with years of steroid treated joint pain and recent onset diarrhea, weight loss and abdominal pain. Ultimately he was found to have a platelet count of 4000 with concomitant endocarditis and embolic stroke. Small bowel biopsy confirmed the diagnosis of WD approximately 1 year after his first visit. His platelets improved with antibiotic treatment but he eventually expired 16 months after his initial consult and 5 months after his definitive diagnosis. CONCLUSION: WD can remain undiagnosed and untreated until late in the course of the illness. A high index of suspicion is recognized as necessary for early diagnosis to begin treatment. Critical thrombocytopenia associated with endocarditis is a rare and potentially poor prognostic sign in late stage Whipple's disease.

Successful Treatment of Hypokalemic Rhabdomyolysis Caused by a Pancreatic VIPoma: A Case Report.

BACKGROUND VIPomas are rare neuroendocrine tumors typically located in the pancreas. The majority of cases autonomously secret vasoactive intestinal polypeptide (VIP), which can result in profuse, refractory, watery diarrhea. The fluid and electrolyte imbalance can progress to dehydration and profound hypokalemia, resulting in the watery diarrhea, hypokalemia, achlorhydria (WDHA) syndrome. One previous case of a pancreatic VIPoma progressing to hypokalemic rhabdomyolysis has been described. CASE REPORT A 33-year-old woman presented with 3 months of progressive, refractory diarrhea and weakness. Her serum VIP level was elevated and imaging discovered a mass in the region of the pancreatic tail. Laparoscopic partial pancreatic resection was performed and a 3.7-cm diameter, solitary stage T2 N0 M0, well-differentiated carcinoma was removed. CONCLUSIONS A high index of suspicion is important when diagnosing chronic diarrhea. Minimally invasive surgery is an option in the surgical treatment of pancreatic VIPoma.

Lymphatic Malformation of the Nasopharynx in a Young Pregnant Female: A Case Report.

BACKGROUND Lymphangiomas represent the focal proliferation of benign, well-differentiated lymphatic tissue. They are most likely congenital, thus more commonly diagnosed at birth and before the age of 2 years. When they are found in adults, they favor the head, neck and axillary region. Rarely do they involve the nasopharynx region or occur in a pregnant patient. CASE REPORT A 21-year-old primagravida in the third trimester of pregnancy developed difficulty swallowing that progressed into difficulty breathing over a 1-month period. Imaging and examination suggested a benign mass in the nasopharynx and the patient underwent surgical removal of the stalk with bipolar cautery. The pathology report revealed a simple 4.5×1.5×0.8 cm lymphangioma. She had no fetal compromise during anesthesia. CONCLUSIONS Surgical removal of a nasopharyngeal lymphangioma during the third trimester of pregnancy is indicated if respiratory obstruction may be a complication.

Clear-Cell Carcinoma of the Ovary with Bilateral Breast Metastases.

Ovarian clear-cell carcinoma is an uncommon subtype of epithelial ovarian carcinoma. It carries a generally poor prognosis because of its resistance to standard treatment and metastatic spread to vital organs. Metastasis to the breast is rare and bilateral breast metastasis is unreported. A 61-year-old white female with a 5-year status poststandard therapy for stage IC clear-cell ovarian carcinoma presented with widespread metastasis. Tissue analysis revealed ovarian cancer metastasis to the breasts bilaterally. Clinical awareness of this metastatic potential is important when staging and developing a treatment plan for patients with ovarian clear-cell cancer.

Epithelioid Hemangioendothelioma: A Rare Case of an Aggressive Vascular Malignancy.

BACKGROUND Epithelioid hemangioendothelioma (EHE) is a rare vascular malignancy that occurs in multiple organs and tissues with a predilection for the extremities, bone, liver, and lung. It is often characterized by a clinically indolent course, delayed diagnosis, and unestablished standardized treatment options. CASE REPORT A 46-year-old female presented with a 2-month history of right shoulder and arm pain. Imaging revealed involvement of the humerus, lung, liver; and brain and biopsies of both the lung and humerus were performed. A diagnosis of epithelioid hemangioendothelioma was confirmed and the patient received radiation therapy to the right humerus and brain stereotactic radiosurgery. She was scheduled to begin palliative chemotherapy with doxorubicin but developed complications and never received chemotherapeutic agents. She died 5.5 months from her first admission with widespread metastasis. CONCLUSIONS Epithelioid hemangioendothelioma (EHE) is typically a low-to-intermediate grade vascular malignancy, but, as seen in this case, can be aggressive. In the future, diagnosis, prognosis, and treatment may improve using genetic or immune therapy considering a structural chromosomal translocation has been identified.

Monotypic IgG1-kappa Atypical Anti-Glomerular Basement Membrane Nephritis: A Case Report.

Anti-glomerular basement membrane (anti-GBM) glomerulonephritis is a rare disease caused by autoantibodies against the glomerular basement membrane. Atypical anti-GBM nephritis is clinically less aggressive and characterized by the absence of circulating autoantibodies to the basement membrane. A previously healthy 53-year-old white woman presented with a rising creatinine over a short observation period. Renal biopsy, urinary sediment, and laboratory testing confirmed the diagnosis of atypical anti-GBM disease. She received plasmapheresis, steroids, and cyclophosphamide. She developed hemorrhagic cystitis early in the treatment from oral cyclophosphamide and mycophenolate mofetil was substituted as a first-line drug. She responded favorably and continued on mycophenolate mofetil without evidence of relapse. Despite the absence of circulating autoantibodies, a diagnosis of atypical anti-GBM nephritis should not be excluded if a high index of clinical suspicion exists. Early renal biopsy should be considered. Mycophenolate mofetil may be a reasonable replacement for oral cyclophosphamide in the treatment of atypical anti-GBM disease when cyclophosphamide is contraindicated.

Successful Use of Adjunctive Red Blood Cell Exchange Therapy for Treatment of an Acute Hemolytic Reaction After ABO-Incompatible Red Blood Cell Transfusion.

An acute hemolytic transfusion reaction is a potentially fatal complication resulting from the transfusion of mismatched blood products. Symptoms vary from mild to severe depending on how much incompatible antigen was transfused and the nature of the recipient's antibodies. There is no consensus agreement of appropriate management other than discontinuing the transfusion and basic supportive methods including adjunctive pharmacologic agents. A 40-year-old male presented with a gunshot wound to the upper torso. During surgery, the O+ patient lost 1.3 L of blood and postoperatively was inadvertently given one unit of A+ packed red blood cells. The blood bank noticed the error and notified the floor within the hour. An acute hemolytic transfusion reaction had progressed to shock and disseminated intravascular coagulation within hours. The clinical course continued to decline despite a norepinephrine drip and a red blood cell exchange transfusion was implemented within 5 h of the mismatched transfusion. The patient's hematological parameters and clinical markers improved and he was eventually discharged in stable condition. An adjunctive red blood cell exchange transfusion may be useful when treating an ABO-incompatible acute hemolytic transfusion reaction if there has been a large volume mismatched transfusion and a poor clinical response to basic supportive methods.

Hemophilia A Complicated by Ulcerative Colitis.

BACKGROUND: Hemophilia A is an X-linked recessive disorder characterized by defective synthesis of Factor VIII protein. Depending on the level of FVIII activity, patients may present with easy bruising, inadequate clotting of traumatic or mild injury, or in severe hemophilia, spontaneous hemorrhage. Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) that is reported to have a decreased frequency of occurrence in subjects with coagulation disorders. CASE: A 26-year-old white male with Hemophilia A was admitted for one month of rectal bleeding. The bleeding continued despite Factor VIII replacement and colonoscopy and biopsy were performed confirming the presence of active UC. CONCLUSION: Ulcerative colitis with underlying F VIII deficiency can result in serious, prolonged, and possibly fatal bleeding if left unrecognized and untreated. Treatment of both conditions concurrently utilizing tertiary facilities and consultations appears to be the safest strategy for management.

Successful Treatment of Severe Type B Lactic Acidosis in a Patient with HIV/AIDS-Associated High-Grade NHL.

Type B lactic acidosis is a rare metabolic complication sometimes associated with hematologic malignancies. When present, this type of lactic acidosis is most commonly seen in patients with high-grade lymphomas or leukemias and is usually indicative of a dismal prognosis. We report a case of a 27-year man with acquired immunodeficiency syndrome (AIDS) that presented with bilateral lower extremity swelling, an abdominal mass, and weight loss. His lab values showed elevated anion gap with lactic acidosis and computed tomography (CT) of the abdomen showed a large soft-tissue mass arising from the left hepatic lobe. Biopsy of the abdominal mass demonstrated a high-grade diffuse large B-cell lymphoma. The patient's lactic acidosis resolved after starting chemotherapy, and a complete response was evident on PET-CT after a third cycle of rituximab, etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin (EPOC-RR). Care-givers should be aware of the implications of lactic acidosis associated with malignancy and the need for prompt diagnosis and treatment.

Burkitt's lymphoma with placental invasion diagnosed at cesarean delivery: a case report.

BACKGROUND: Burkitt's lymphoma is a highly aggressive B cell non-Hodgkin lymphoma subtype. Its occurrence in pregnancy is rare and often results in a delayed diagnosis. The treatment plan and prognosis depend on a number of variables including the stage at diagnosis. CASE PRESENTATION: A 32 weeks pregnant, 34-year-old white woman presented with weeks of complaints that were similar to typical pregnancy symptoms. Laboratory and ultrasound findings suggested a pathologic process and during the workup non-reassuring fetal surveillance resulted in an emergency cesarean delivery. Biopsies were obtained that confirmed Burkitt's lymphoma. Placental histology revealed microscopic involvement. CONCLUSIONS: The placenta should be inspected for microscopic disease if Burkitt's lymphoma is suspected, even if a vaginal delivery occurs and the placenta is ordinarily discarded. Repetitive somatic complaints during pregnancy should not be assumed to be secondary to the normal symptoms of pregnancy.

Successful pregnancy after mucinous cystic neoplasm with invasive carcinoma of the pancreas in a patient with polycystic ovarian syndrome: a case report.

BACKGROUND: The incidence of invasive cancer within a mucinous cystic neoplasm of the pancreas varies between 6 and 36%. Polycystic ovarian syndrome is a disorder characterized by hyperandrogenism and anovulatory infertility. One surgical treatment that can restore endocrine balance and ovulation in polycystic ovarian syndrome is partial ovarian destruction. Successful pregnancies following preconception pancreaticoduodenectomies (Whipple procedures) and chemoradiation to treat pancreatic neoplasms have been reported rarely but none were diagnosed with pre-cancer polycystic ovarian syndrome-associated infertility. Gemcitabine is an antimetabolite drug used for the treatment of pancreatic cancer that can have profound detrimental effects on oogenesis and ovarian function. Whether the ovarian destructive property of gemcitabine could act as a method to restore ovulation potential in polycystic ovarian syndrome is unknown. CASE PRESENTATION: A 40-year-old white American woman with a history of pancreatic cancer treatment with a Whipple procedure and chemoradiation with gemcitabine had a successful pregnancy after years of pre-cancerous anovulatory infertility and polycystic ovarian syndrome. She received no fertility agents and delivered full term via a spontaneous vaginal delivery with no pregnancy complications. CONCLUSION: Gemcitabine treatment for pancreatic cancer may result in resumption of ovulation in women with polycystic ovarian syndrome and these women should be counseled accordingly.

Reactivation of Goodpasture Disease During the Third Trimester of Pregnancy: A Case Report.

BACKGROUND: Active Goodpasture disease (GD) in pregnancy is extremely rare and can result in significant maternal and fetal morbidity. Relapse of GD in a subsequent pregnancy has not been reported. Factors associated with a relapse of GD are unknown. CASE: A woman in her second pregnancy presented with clinical findings of preeclampsia and biopsy evidence of GD in the third trimester. Her first puerperium was also complicated by GD, requiring temporary hemodialysis. After her second pregnancy she developed terminal renal failure. CONCLUSION: Active GD is extremely rare in pregnancy and has never been reported in 2 successive pregnancies in the same patient. Pregnancy and preeclampsia may be risk factors for a GD relapse, and women with GD contemplating pregnancy should be counseled accordingly.
