Peripheral nerve sheath tumors are a heterogenous group of predominantly benign tumors of neurogenic origin that arise outside of the central nervous system and include schwannomas and neurofibromas. These tumors often occur sporadically, however multiple lesions are generally associated with genetic syndromes such as neurofibromatosis (type 1 and 2) and schwannomatosis, and occasionally these tumors and their malignant variations are associated with a history of radiation treatment. Multiple benign schwannomas in an irradiated field have seldom been reported in the literature. We describe a case of a 49-year-old male with a history of right sided irradiated testicular cancer who presented with 2 histologically confirmed benign schwannomas in the right pelvic wall and right psoas muscle.

Pulmonary alveolar proteinosis (PAP) is a rare disease, which is characterized by the alveolar accumulation of surfactant. A crazy-paving appearance on chest thin-section computed tomography (TSCT) is a characteristic feature of this disease. We report an unusual case of PAP, which presented as multiple localized ground glass opacites (GGOs) on TSCT in an 80-year-old female. As one of these lesions at the apex of the right lung increased in size, it was suspected to be a pulmonary adenocarcinoma. However, the others became smaller during the follow-up period. Right upper lobectomy was performed, and PAP was histologically diagnosed. In cases exhibiting multiple localized GGOs, PAP should be considered, even if GGOs with a crazy-paving-like appearance are distributed in a lobular rather than diffuse manner.

Silicone granuloma formation is a potential complication of silicone implant rupture. Breast magnetic resonance imaging (MRI) is a useful diagnostic tool to assess implant integrity and complications; however, there can be overlap in the enhancement pattern of silicone granuloma and malignancy. We present the case of an 85 year old with suspicious axillary masses on clinical exam for which MRI was recommended. MRI demonstrated enhancing masses in the right axilla that were suspicious for malignancy and biopsy was ultimately performed. This case discusses the use of inversion recovery sequences on MRI, as well as ultrasound, to differentiate malignancy from silicone granuloma formation to prevent unnecessary biopsies.

Spinal schwannomas are benign lesions that most commonly appear in the lumbar and thoracic regions of the spine. Although computed tomography (CT) scans are often used to assess spinal conditions, they are ineffective at detecting soft tissue abnormalities. This case is for a 49-year-old female who experienced a gradual loss of sensation and strength in her lower extremities, along with increased urinary urgency, over six weeks. In addition, mid-back pain has been present for one year. Initially, a CT scan was done and did not show any significant findings, which suggested the absence of a spinal abnormality. However, magnetic resonance imaging (MRI) revealed an intradural extramedullary lesion causing spinal cord compression. The patient successfully underwent surgery to remove the tumor, and histological analysis confirmed it as spinal schwannoma. This case underlines the diagnostic limitations of CT imaging for spinal lesions and illustrates the superior accuracy of MRI. Thus, a negative CT should not halt further diagnostic evaluation when symptoms persist.

Cystic lymphangioma is a benign lymphatic malformation that primarily affects children, with rare occurrences in adults. These malformations are most commonly found in the head and neck region, though their presence in the abdominal cavity is infrequent. In this report, we present the case of 71-year-old women with a cystic lymphangioma located in the omental bursa. The rarity of this condition in adults, combined with its unusual abdominal location, highlights the unique aspects of this case. This report explores the clinical presentation, diagnostic challenges, and management strategies for these uncommon lymphatic malformations.

Myelomeningocele, a severe form of open neural tube defect which is mostly associated with Chiari II malformation remains a cause of adverse neonatal outcomes. Myelomeningocele is mostly detected in the second trimester and subsequently followed up in the third trimester. We present a case of myelomeningocele with associated Chiari II malformation that was diagnosed for the first time in the third trimester in a 32-year-old pregnant woman. Previously performed ultrasound at 12 weeks gestation was unremarkable. Considering the prognosis of the detected anomalies, the patient opted for medical termination of the pregnancy after receiving thorough counselling.
Third trimester anomaly screening should be encouraged as part of routine third trimester scans; particularly in women who report late for antenatal care and those who lack periconceptional folate supplementation.

We present a case of a 70-year-old male who presented with left-sided weakness and dysarthria. Cranial imaging was suggestive of a cerebellar infarct and the patient was treated with aspirin and clopidogrel. Two months later a fall prompted further cranial imaging, which was concerning for an intracranial mass with vasogenic edema. Computed tomography angiogram (CTA) was negative for vascular lesion. Ultimately, a DSA revealed a Borden III dAVF between the right occipital artery and the posterior cerebellar vein that was treated with endovascular embolization.

Antiphospholipid syndrome (APS) is characterized by hypercoagulability, manifesting as venous or arterial thrombosis, and pregnancy-related complications, such as fetal loss, pre-eclampsia, and eclampsia. These conditions occur in the presence of antiphospholipid antibodies (aPL), including anticardiolipin antibodies (aCL) and/or a positive lupus anticoagulant (LA) test.
Antiphospholipid syndrome (APS) can manifest as a primary, isolated condition or be associated with connective tissue diseases, such as systemic lupus erythematosus (SLE). The cardiac system is one of the main target organs affected by APS.
This report describes a rare clinical case involving a young woman with a history of recurrent miscarriages, who presented with cardiac complications, including severe mitral regurgitation and Spontaneous coronary artery dissection. Etiological assessment identified antiphospholipid antibody syndrome as the underlying cause.
The multidisciplinary management plan included initiating therapeutic-dose anticoagulation, followed by referring the patient for potential mitral valve replacement surgery.

An acute aortic dissection can be a tremendously fatal vascular condition if not managed promptly. However, the symptom profile of aortic dissections can be ambiguous to numerous conditions which are more common and greater pursued by clinicians before suspicion of dissection is made. The case presented in this study is of a 61-year-old male who arrives to the emergency department for concern of new-onset chest pain which progresses into ventricular fibrillation arrest prior to diagnosis of aortic dissection. This case report profiles the mimicking possibility of aortic dissection to present as acute myocardial injury, and the utility of models use to differentiate the workup between aortic dissections and acute coronary syndromes.
