Medicolegal evaluation of pontine hemorrhage at autopsy- Highlights from a case and an overview

One in ten non-traumatic intracerebral hemorrhages (ICH) is located in the pons with chronic arterial hypertension as the leading etiology. In the forensic context, deaths related to a pontine hemorrhage (PH) are usually encountered in situations of drug abuse, excited delirium, trauma, as well as in sudden natural deaths where some hypertensive catastrophe is the usual underlying mechanism. The clinical presentation of PH may be variable, causing a failure in timely diagnosis that, if presents with unexplainable circumstances, may become the subject of medicolegal concern. The present case relates to a middle-aged man with a long history of hypertension and presents during an afternoon with an abrupt onset of deleterious symptoms. The patient was managed conservatively but succumbed to his illness and expires during treatment. A questionable diagnosis and the case circumstances, however, directed the doctors to inform the police. A medicolegal autopsy was therefore carried out that leads to the discovery of a lethal pontine hemorrhage rupturing into the fourth ventricle and involving the adjacent cerebellar tissues as well. Severe atherosclerosis of the basal arteries constituting Circle of Willis and Vertebrobasilar system was seen along with their hallmark effects that became evident during brain sectioning. Pathological stigmata of well established hypertension were found in the heart and kidneys. A clinic pathological correlation of the physical characteristics and topography of the hematoma to its severity was also carried out, based upon the known CT and autopsy findings. The possibility of a drug related or traumatic and secondary brainstem/Duret hemorrhage was ruled out.

Primary Brainstem Hemorrhage: A Review of Prognostic Factors and Surgical Management

Primary brainstem hemorrhage (PBSH) is the most fatal subtype of intracerebral hemorrhage and is invariably associated with poor prognosis. Several prognostic factors are involved, of which the two most predominant and consistent are the initial level of consciousness and hemorrhage size. Other predictors, such as age, hyperthermia, and hydrocephalus, are generally not dependable indicators for making prognoses. Scoring systems have now been developed that can predict mortality and functional outcomes in patients suffering from PBSH, which can thus guide treatment decision-making. A novel grading scale, entitled “the new primary pontine hemorrhage (PPH) score,” represents the latest approach in scoring systems. In this system, patients with a score of 2–3 points appear to benefit from surgical management, although this claim requires further verification. The four main surgical options for the treatment of PBSH are craniotomy, stereotactic hematoma puncture and drainage, endoscopic hematoma removal, and external ventricular drainage. Nevertheless, the management of PBSH still primarily involves conservative treatment methods and surgery is generally not recommended, according to current practice. However, the ongoing clinical trial, entitled Safety and Efficacy of Surgical Treatment in Severe Primary Pontine Hemorrhage Evacuation (STIPE), should provide additional evidence to support the surgical treatment of PBSH. Therefore, we advocate the update of epidemiological data and re-evaluation of PBSH treatment in a contemporary context.

Neuroleptic Malignant Syndrome Applied with Targeted Temperature Management

Neuroleptic malignant syndrome (NMS) is a life-threatening neurologic emergency associated with the use of dopamine receptor-antagonist properties or the rapid withdrawal of dopaminergic medications. NMS is characterized by refractory hyperpyrexia, altered mental state, dysautonomia, and rigor. If hyperpyrexia persists, it can result in multiorgan failure. Herein, we report a case of NMS occurring after metoclopramide administration in a patient with pontine hemorrhage, which was successfully treated with targeted temperature management using a surface cooling device.

Pontine hemorrhage presenting as Foville’s syndrome

Foville’s syndrome, also known as inferior medial pontine syndrome is one of the rare brainstem stroke syndromes with only few cases reported worldwide occurring due to involvement of the infero-medial aspect of pons. Condition is characterised by various cluster of neurological features as a result of defect in multiple vital areas like cortico spinal tract, medial lemniscus, middle cerebral peduncle, facial nerve and abducens nerve involvement. We reported one such rare case of a patient with no known systemic co-morbidity, who presented with sudden onset diplopia, lagophthalmos and contralateral weakness of limbs. On evaluation with computed tomography imaging, hemorrhage at the level of inferior pons was found. Patient subsequently treated and commenced on physiotherapy for rehabilitation.
