Blood-filled cysts of the heart valves are frequently reported at postpartum autopsies of infants. They are seen as round nodules mostly in the paediatric age group in infants less than 2 months of age and disappear spontaneously within 6 months of life. We report a unique case of an 11-month-old girl who presented at a tertiary healthcare hospital in 2022 with a blood-filled cyst on the posterior leaflet of the pulmonary valve that was successfully treated. This case report highlights the characteristics and course of a paediatric patient with blood-filled cysts. Further studies are yet needed to better understand the diagnostic approaches to blood-filled cysts as well as treatment modalities to fill the gap in clinical settings.

Peri-ictal water drinking (PIWD) is a rare vegetative manifestation of temporal lobe epilepsy without a definite lateralisation value. We report a case of PIWD in a 22-year-old Omani male patient with post-concussion syndrome and epilepsy presented to a tertiary care hospital in Muscat, Oman, in 2021 for evaluation of paroxysmal events. His behaviour of PIWD was misinterpreted by his family until characterised in the epilepsy-monitoring unit as a manifestation of epilepsy that was treated medically. To the best of the authors' knowledge, this is the second reported case in the region.

Failure of sub-arachnoid block (SAB), due to resistance to bupivacaine after a recent scorpion sting can lead to multiple block attempts and subsequent conversion to general anaesthesia. We report this case series of 10 patients with successful SAB with newly launched 0.75% hyperbaric ropivacaine, in patients with recent scorpion sting. Thus, intrathecal hyperbaric ropivacaine may be considered as the local anaesthetic agent of choice in patients with scorpion sting to prevent failure of SAB.

Ramsay Hunt syndrome (RHS) is a triad of peri-auricular pain, ipsilateral facial nerve palsy and vesicular rash around the ear pinna. It is caused by reactivation of varicella-zoster virus (VZV) that lies dormant in the geniculate ganglia. It can be complicated by VZV encephalitis rarely. We report the case of an 8-year-old previously healthy boy who presented to a tertiary care hospital in Muscat, Oman in 2021 with fever, progressive left ear pain, vesicular rash around his ear pinna and left-sided facial nerve palsy. His course was complicated by VZV encephalitis where he was managed with intravenous (IV) acyclovir and IV corticosteroids. He improved significantly and was asymptomatic with a normal neurology examination at the 6-months follow-up.

Dermoid cysts are common benign ovarian tumours arising from totipotent germ cells. We report a rare case of chemical peritonitis and prolonged fever following laparoscopic salpingo-oophorectomy for torsion of a large ovarian dermoid and discuss the management of this patient with prolonged hospital stay, antibiotics and anti-inflammatory use, repeated drainage of the collection as well as re-laparotomy. The occurrence of this rare condition can be extremely distressing for the patient and treating surgeon alike, as the recommendations for management are limited. The management of chemical peritonitis may require one or more surgical procedures along with prolonged anti-inflammatory therapy.

Crescentic glomerulonephritis has been associated with several solid tumour malignancies. Only a few cases of nephropathy have been reported in association with tubo-ovarian/peritoneal malignancies. We report a 55-year-old female patient who presented to a tertiary care centre, Muscat, Oman, in 2022. She developed combined immune complex-mediated glomerulonephritis and pauci-immune necrotising crescentic vasculitis simultaneously with the diagnosis of tubo-ovarian/peritoneal cancer. The baseline estimated glomerular filtration rate (eGFR) was 13 mL/min. The patient received two doses of rituximab and three doses of pulse corticosteroids, leading to significant improvement in renal function and the disappearance of her proteinuria. The eGFR improved to >60mL/min; her proteinuria gradually resolved after 10 weeks of treatment. She was then given a combination chemotherapy treatment for tubo-ovarian/peritoneal cancer leading to a normalisation of her CA-125 after three months of therapy.
