ANGIOMYOLIPOMA DURING PREGNANCY: A FORGOTTEN RISK FACTOR FOR RUPTURE AND MASSIVE HAEMORRHAGE– A CASE REPORT Benign renal lesions are relatively rare. Angiomyolipoma (AML) is the most commonly encountered benign renal lesion. One of the complications of AML is rupture, which results in retroperitoneal haemorrhage with a mortality rate of up to 20%. Pregnancy poses a major risk for the rupture of AML. This is attributed to its hormonal effect, which causes the tumour to grow rapidly during pregnancy. The possibility of AML rupture should be considered when encountering pregnant patients with hypovolemic shock but with normal initial obstetric ultrasound findings. We present a case of a pregnant patient who was admitted with hypovolemic shock and CT scan confirmed rupture of AML.

Osteosarcoma is the most frequent primary malignant mesenchymal bone tumour in children and adolescents. Although the lung is the most common site of its metastasis, to the best of our knowledge, it is infrequent to have hypervascular pulmonary metastasis, particularly in the post-operative period. Herein, we report a case of a 15-year- old boy who presented with a rapidly enlarging lung mass on a background of osteosarcoma of left proximal tibia. The progressively enlarging right lung mass was detected as an opacity on a chest radiograph, three months post-surgical resection of the osteosarcoma. Computed tomography of thorax revealed a contrast-enhancing hypervascular right lung mass. This was complicated with intra-lesional haemorrhage post-biopsy. Histopathological examination (HPE) confirmed metastatic osteosarcoma. We discuss the rarity of this occurrence and its imaging findings.

Hybrid chest lesion is an uncommon congenital thoracic anomaly. We report a case of hybrid chest lesion in a neonate, who was initially treated for congenital pneumonia. The initial computed tomography thorax in portovenous phase was performed due to persistent opacities at right mid and lower zones on chest radiograph. The echocardiographic findings were suspicious of congenital cardiovascular anomalies. The subsequent ECG-gated CT angiography thorax demonstrated features consistent with hybrid lesion, together with its vascular anomalies which were confirmed intraoperatively and histologically. The baby underwent a successful surgery to resect the sequestrated lobe with plication of the right diaphragm and is doing well.

ABSTRACT Kimura disease (KD) is a rare chronic inflammatory disorder of unknown aetiology that primarily affects the head and neck region with lymph node involvement. Young to middle-aged adult Asian males are predominantly affected. The most common presentation is painless subcutaneous swelling in the head and neck region, while proptosis or orbital involvement is very rarely reported. KD shares some features with other inflammatory and neoplastic disorders, including lymphoma; thus, investigations to confirm the diagnosis should not be delayed. Systemic corticosteroids are commonly used to treat KD and show an excellent response; however, the optimal treatment is still uncertain, and KD has a high recurrence rate. We describe the case of a patient with KD who presented with proptosis and post-auricular swelling, which responded well to oral prednisolone treatment.

Cervical vagal schwannoma is an uncommon, benign neoplasm. It is usually asymptomatic and presents as a painless, palpable mass in the neck. However, large schwannomas can cause dysphagia, dysphonia or dyspnea as a result of compression. We report a case of an extremely rare complication of vagal schwannoma in which neck palpation induced the patient to cough. As the patient refused any surgical intervention, conservative management was used.
