Vein of Galen aneurysmal malformation is a rare entity in the paediatric population. However, it is being recognised with increasing frequency due to better diagnostic techniques. Neonates usually present with congestive heart failure, while in older infants and children it tends to manifest with seizures, hydrocephalus, intracerebral or subarachnoid haemorrhages. We present a case of ruptured vein of Galen aneurysmal malformation in a 3-month-old baby boy treated by transarterial embolisation using Guglielmi detachable coils.

Lithium salts have been used in treatment of depression and bipolar disorder for more than 50 years. Neurotoxic side-effects such as nystagmus, ataxia, tremor, fasciculation, clonus, seizure and even coma have been well described in the literature. We present a case of generalised peripheral neuropathy following lithium intoxication. It is a rare presentation with delayed onset and characterised by a rapid downhill course. Diagnosis was confirmed by nerve conduction tests, which showed axonal neuropathy. Despite the profound neurological effects of this toxicity, it is readily reversible with supportive care and the prognosis is good.

Sclerosing stromal tumour of the ovary is rare. Patients present with menstrual irregularities, pelvic pain, abdominal distension, and presence of a large pelvic mass during their twenties or thirties. We report a rare case of an ovarian sclerosing stromal tumour with an atypical presentation, in that it gave rise to recurrent postmenopausal bleeding.

This report describes a 31-year-old woman with a 23-year history of a right buttock mass that was otherwise asymptomatic, but was proven to be a low-grade fibromyxoid sarcoma (a fully malignant soft tissue tumour with a potential for distant metastasis). This case illustrates that a long-standing tumour does not necessarily imply a benign pathology. A vigilant approach should be taken for any tumours that are of significant size (larger than 5 cm).

Thalassaemia is the most common haemoglobinopathy in the Chinese population. However, recurrent painful digital swelling is not a typical manifestation of this well-known hereditary condition. We describe a case of co-inheritance of beta-thalassaemia and sickle cell trait in a Chinese family and a child who suffered from sickle cell/beta-thalassaemia with recurrent dactylitis. This report highlights awareness of this rare condition in the Chinese population, since acute manifestations can be life-threatening and mimic other emergency conditions. Prompt management can prevent further complications and avoid unnecessary interventions due to delay in diagnosis. A detailed family history and examination of the patient's peripheral blood smear is crucial to reach a correct diagnosis.
